What does 'passive investing' really mean? | (R news & tutorials)

We know the words but what do they mean?

Some definitions

Here are some definitions of ?passive investment management?.

Investopedia says:

A style of management associated with mutual and exchange-traded funds?(ETF) where a fund?s portfolio?mirrors a market index.

Wikipedia says:

Passive management (also called passive investing) is a financial strategy in which an investor (or a fund manager) invests in accordance with a pre-determined strategy that doesn?t entail any forecasting

Qfinance says:

the managing of a mutual fund or other investment portfolio by relying on automatic adjustments such as tracking an index instead of making personal judgments.

The Free Dictionary says:

The practice of a money manager or a team of money managers making investment decisions on what securities to include in a fund or portfolio, and then leaving those securities largely unchanged for a significant period of time.

Investorwords says:

An investment strategy that involves buying and holding a portfolio of securities that track the broader market. Index funds are an example of passive investment management, but individual investors who employ a buy and hold strategy use it as well.

My view

I don?t see any of those definitions as really wrong, but I don?t think any are entirely right.? I prefer to think in terms of Figure 1 that considers two dimensions: turnover and effort.

Figure 1: Schematic view of passive versus active management.

The bottom axis is ?buy and hold?.? Some people seem to think this is the entirety of ?passive?.? At the point (0,0) is the ?grandparent portfolio? ? the stocks your grandparents gave you when you were a child that you continue to just hold.? This is the ultimate passive portfolio.

Index funds are indicated as having a fairly specific turnover and a range of effort.? The turnover of an index fund is largely determined by the turnover of the index.? The effort depends mostly on how closely the index is tracked.

In contrast, minimum variance is characterized as having a narrow range of effort but a wide range for turnover.? The turnover will depend on how often and stringently rebalancing is done.? The amount of effort for minimum variance is perhaps overstated in the graph.? All you need is some data, a variance estimator and an optimizer (not even a very good one) ? you could be up and running in an afternoon.

I divide ?passive? into three groups:

  • index funds
  • buy and hold
  • other strategies with low turnover and low effort

Is low volatility investing passive?

By my definition: maybe, maybe not.? Low volatility investing could be done exceeding simply.? Or a volatility screen could be imposed on a very active strategy.

Likewise minimum variance could be used within highly active strategies.? The trade list could be created in a labor-intensive manner, but the weights determined by minimizing variance.

The religion of active versus passive

The discussion of passive versus active includes a great deal of divisiveness: ?You have to pick one or the other, and shame on you if you pick the wrong one.?? A lot of this centers on the efficient market model.

I think everyone agrees that it is irrational to believe that markets are efficient and select active management.

One posture that I find interesting is: ?If you do not believe in efficient markets, then you must choose active management.?? Why?

The interesting posture on the other side of the fence is: ?If you believe in efficient markets, you must use index funds.?? (We?ll skip over the bit about how markets would become efficient if there were no active managers.)? This is another symptom of people believing their models ? the index is ?the market?.? In reality an index is just someone?s trading strategy that has come to be set in stone.? There are reasons to be concerned about index funds.

I suspect that there are creative ways waiting to be discovered that provide low cost and valuable funds for investors while being profitable for fund managers.

Questions

Are there other dimensions in addition to turnover and effort that should be considered?

Epilogue

Don?t prophesize
I could hold you in my arms
I could hold you forever

Religion Is Not America’s Enemy

Topics: Faith, Political News and commentaries

Philip F. Lawler’s must-read piece at The American Spectator today is on the warnings given in Marcello Pera’s book, “Why We Should Call Ourselves Christians: The Religious Roots of Free Societies.” Pera is a seasoned politician, former president of the Italian Senate, an agnostic, and a secularist. A philosophy professor before and after his political career, he studied Karl Popper and defends the traditions of European liberalism, which have historically been at odds with the public stands of the Catholic Church.

As Lawler points out, although an agnostic and a secularist, Marcello Pera has made common cause with the Pope because he is convinced that Europe cannot survive as a free and democratic society without recognizing its cultural roots in Christianity. As we are now seeing in America under the Obama administration, while European leaders have been building up needless defenses against the nonexistent threat of Christian fundamentalism, they have exposed their societies to the very real threat of Islamic fundamentalism. Having decided that all religious faith is dangerous, Europe’s elites have no way to counteract the influence of a faith that is foreign to European traditions and hostile to European interests. Pera laments: “The bitter truth is that the West is afraid of Islam because it is afraid of religion, and of its own religion first of all.”

Pera concedes that the Church is not without flaws, and writes:

… But in the end, how can we fail to see that without the Catholic Church, Europe would have disappeared not once but countless times, and the West would have lost its civilization…. How can we fail to realize that when other institutions, parties, movements, or systems’ political, philosophical, juridical, economics — are in error, they simply cease to attract adherents or they disappear, but when the church errs, its very errors exalt the grandeur of its message, the noncontingent value of its words, and the spiritual reality to which it bears witness?

Here’s a key excerpt from the rest of Lawler’s excellent piece:

[...] From the time of St. Augustine, Christian Europe understood the separate roles of Church and state, the City of God and the City of Man. Although there were border violations aplenty over the centuries, when normal relations were restored, political and religious leaders agreed on certain fundamental points: that religious freedom should be upheld, that the church should not be a tool of the regime; that individuals should be treated with dignity whatever their beliefs. These three basic principles, Pera notes, are diametrically opposed to the instincts of both authoritarian government and religious fundamentalism. They are the guarantees of European democracy.

Unfortunately, Pera writes, the secularism of post-Enlightenment Europe — the secularism of Locke and Kant, which sought to preserve the instruments of government from usurpation by clerics — has been replaced in our time by a more militant form that sees religion itself as an enemy. European intellectuals have fled from the Christian tradition, claiming a fear of fundamentalism — when it is that very Christian tradition that provides their best defense against fundamentalism.

Moreover, while European leaders have been building up needless defenses against the nonexistent threat of Christian fundamentalism, they have exposed their societies to the very real threat of Islamic fundamentalism. Having decided that all religious faith is dangerous, Europe’s elites have no way to counteract the influence of a faith that is foreign to European traditions and hostile to European interests. Pera laments: “The bitter truth is that the West is afraid of Islam because it is afraid of religion, and of its own religion first of all.”

There is an old chestnut in politics: “You can’t beat somebody with nobody.” If you don’t have a candidate in the race you will lose, regardless of your opponent’s weakness. In Europe today, Islamic culture is making steady inroads because European culture is too weak or too complacent to offer any resistance. “If Europe is not a melting pot but only a container,” reasons Pera, “this is because it does not have enough energy to melt down and fuse its contents.” (Readers in the United States, the pre-eminent melting pot, should take note. When the siren calls of “diversity” render us deaf to any appeal to a common heritage, chaos is just around the corner.)

It’s very much worth your time to read the whole thing.

Lawler goes on to point out that Pera later writes the secularism of post-Enlightenment Europe — the secularism of Locke and Kant, which sought to preserve the instruments of government from usurpation by clerics — has been replaced in our time by a more militant form that sees religion itself as an enemy. European intellectuals have fled from the Christian tradition, claiming a fear of fundamentalism — when it is that very Christian tradition that provides their best defense against Islamic fundamentalism.

Unfortunately, that very same militant form of secularism is the very same kind the current occupant of the White House has embarked upon — and the resulting vulnerabilities to Islamic fundamentalism has already being demonstrated by the Europeans.

Take home message: Religion is not America’s enemy: Our enemy is Barack Obama’s brand of nanny state secularism and the militant Islam that it invites.

(AP) ? Syria’s military sent tanks and other reinforcements toward the restive central city of Homs on Monday in what appears to be preparations by President Bashar Assad’s regime for an offensive aimed at retaking rebel-held neighborhoods, activists said.

Syria-based activist Mustafa Osso told The Associated Press he does not think the regime will be able to retake Homs through military force as residents plan to fight until “the last person.” He added that Homs is facing “savage shelling that does not differentiate between military or civilians targets.”

Rami Abdul-Rahman, who heads the Britain-based activist group Syrian Observatory for Human Rights, said he expects the regime to try retake the Baba Amr district of Homs. Many Syrians call Baba Amr “Syria’s Misrata,” a reference to the Libyan city where rebels fought off a brutal government siege for weeks, managed to hold the city and went on to play a key role in overthrowing dictator Moammar Gadhafi last year.

“The human loss is going to be huge if they retake Baba Amr,” Abdul-Rahman said.

The Observatory said that Monday’s shelling of Baba Amr killed five civilians.

In neighboring Lebanon, security officials said at least three wounded Syrians were brought for treatment in the eastern town of Chtoura. The officials, who spoke on condition of anonymity in line with regulations, said the wounded came from the Baba Amr attacks.

Amateur videos posted online showed what activists said were shells falling into Baba Amr. Black smoke billowed from residential areas.

Clashes between military rebels and Syrian forces are growing more frequent and the defectors have managed to take control of small pieces of territory in the north as well as parts of Homs province, which is Syria’s largest stretching from the border with Lebanon in the west to Iraq and Jordan in the east. Increasingly, Syria appears to be careening toward an all-out civil war.

Assad’s authoritarian regime may be trying to subdue Homs ? an important stronghold for anti-Assad groups ? before a planned referendum Sunday on a new constitution. The charter would allow a bigger role for political opposition to challenge Assad’s Baath Party, which has controlled Syria since a 1963 coup.

But the leaders of the 11-month-old uprising against Assad have dismissed the referendum as an attempt at superficial reforms that do nothing to crack the regime’s hold on power. Assad still counts on support from Iran and allies such as Russia, which fears losing its main Arab partner. But his government is facing escalating pressure and isolation from Western and Arab states.

In Kabul, two senior members of the U.S. Senate Armed Services Committee urged international cooperation to help supply the anti-Assad rebels with weapons and other aid. Both Arizona Sen. John McCain and Sen. Lindsey Graham of South Carolina, however, stopped short of endorsing direct U.S. military involvement.

“The United States doesn’t have to directly ship weapons to the opposition, but there are a whole lot of things that can be done” through groups such as the Arab League, McCain told reporters.

Graham said it was “shameful” for the U.S. not to have a prominent role to help the rebel forces, saying that breaking Syria’s ties to Iran “could be as beneficial to our efforts to contain a nuclear armed Iran as sanctions.”

“If the Syrian regime is replaced with another form of government that doesn’t tie its future to the Iranians, the world is a better place,” he said.

Osso said the three convoys heading toward Homs comprise dozens of vehicles from the eastern suburbs of the capital Damascus, an area that was reclaimed by Assad troops from rebels late last month.

In embattled Homs, rebel-held neighborhoods such as Baba Amr and Khaldiyeh have been under government attack since Feb. 4. Phone lines and Internet connections have been cut with the city, making it difficult to get firsthand accounts from Homs residents.

The U.N. last gave a death toll for the conflict in January, saying 5,400 had been killed in 2011 alone. But hundreds more have been killed since, according to activist groups. The group Local Coordination Committees says more than 7,300 have been killed since March of last year. There is no way to independently verify the numbers, however, as Syria bans almost all foreign journalists and human rights organizations.

The Observatory said that troops conducted raids Monday in the southern village of Harrah where at least nine people were detained.

On Sunday, activists said at least 18 people were killed in Syria, including a senior state prosecutor and a judge who were shot dead by gunmen in the restive northwestern province of Idlib.

Bad Credit Car Loans ? 3 Tips ? Management, Business, Finance

Along the way to getting your next vehicle, if you have bad credit, you should consider a few things first. There is a lot of misinformation on the internet regarding car loans and what is truly available for people that have bad credit, in regards to auto financing. This article will help you.

First of all, there is no such thing as guaranteed auto finance. While buy here pay here car lots may offer financing with no credit check, they do have you to sign a waiver that you are not involved in a bankruptcy. Also, you will be required to put down a down payment at any dealer that offers in house financing for cars. Unfortunately, there are no dealers in the nation that offer buy here pay here motorcycle financing, just to note.

Secondly, when you obtain a real car loan through a dealership, bank, online lender or so forth, the only time that a down payment is necessary is if the total price that is requested for finance exceeds the loan value percentage.

This is the advance amount above the loan value of the vehicle. Commonly, bad credit car loan companies will allow a certain percentage over the loan value of the car, to be allowed for financing. If you get a good price on the vehicle, there is no need for a down payment.

Third, you should never accept the first deal that you are offered. Just because you have a few credit problems, does not mean that you can?t shop around just like everyone else, and compare to get the best terms according to your budget.

Kris Humphries on Jeremy Lin: Nice Guy!


Kris Humphries heard it once again at Madison Square Garden last night: BOOOOO!

But this time the Nets power forward left The World’s Most Famous Arena with a reason to smile, despite the reception he received by opposing fans, as New Jersey defeated New York 100-92. Humphries played a key role in the victory, too, with 14 points and 14 rebounds.

Red Karpet KrisJeremy Lin Pic

“I love the hostile environment,” Humphries told ESPN after the game. “There’s nothing better than sending 19,000 people home upset… We love that.”

Kris is also the latest in a very long lien to give props to Jeremy Lin, the NBA’s latest sensation, but not for anything the Harvard graduate did on the court last night. Instead, Lin apparently gave Kris a big assist in the tunnel leading to the locker rooms.

“He just said, ‘Hey, I don’t know why they boo you, but I think it’s crap, and you’re playing really well,’” Humphries said of Lin. “That was nice of him to say. He’s a really nice guy… It’s nice to see great things happen for nice people.”

Lin also has great taste in women: he recently said Kim Kardashian was not his type.

Reasons to Write Into Art: On Textual Collaboration with Artist Heidi …

Focusing on the relationships/constellations between the act of writing, the process of research, and contemporary visual art practices is how I?ve attempted to anchor this series of guest blog posts, but until this winter I could only have spoken to the first two. It?s curious that as a critic and arts writer, you can work full-time to become as fully fluent as possible in the language of contemporary visual art?recognizing it, and occasionally producing its most important turns of phrase, without ever actually speaking it yourself, so to speak. (In other words, so many people who write about art only ever have to learn enough to be able to identify the most important connections, the most obvious expressions, and so forth, without ever learning how individual words and phrases might actually translate to everyday practice.)

Then one day last spring I bought a piece of work by Heidi Norton, my first real significant art purchase, after seeing her show at ebersmoore gallery (the title of the piece I bought, The Radicant, also happened to be precisely the same as that of a Bourriaud book I was arguing with in my head at the time), and I began an email conversation with her about her work, after which she invited me by for a studio visit. The rest of that history should make up a blog-post-long disclaimer about conflict of interest as a writer, because I want to write about a show that I was involved in creating?and what I learned about the process of making artist books and more generally making text that?s part of a visual art show rather than a response to one. So, here is my disclaimer:?this entire blog post is a conflict of interest (and in a way, it is also about that very conflict).?

Some very brief background on Heidi?s work: She works in photography, living plants, wax, the earth, and is influenced deeply by the light and space movement. Her photographs are among the most exquisite surfaces I?ve ever seen.

Heidi Norton. “My Dieffenbachia Plant with Tarp (Protection),” 2011. Archival Pigment Print, 30×36 in.

Her wax pieces, which is the genre of piece I bought, are heavy, lumbering, decaying chunks of wax encasing living plant material that eventually dies and falls out (frieze critic?Jason Foumberg, who is also my editor at New City, compared them to dead dissections of scientific specimens; I told you this was one long conflict-of-interest piece).

Heidi Norton. Untitled, 2011. Wax and mixed media.

Heidi was an ACRE (Artist?s Cooperative Residency and Exhibitions) resident in Wisconsin this summer, where she built a studio in the woods, digging holes in the earth to embed wax, creating shelves in rock walls in which she photographed found objects. After talking to her via email a few times this fall, I went to her studio to see about a possible collaboration, where I saw the work she had made, through intervening with studio materials in the earth, and the photographs she had taken there of that practice.

?Heidi and I agreed to work together to produce a kind of field guide to the work (not a stretch, as much of the work had to do with the geological history of the area, the role of the natural studio, and themes like erosion and floriography). What became interesting to me as a critic was the process that followed, particularly the haziness between critic and participant.

To that end, I can?t review the show at Johalla, which closes next weekend. (For information and images from the show, see the gallery?s website).?I can?t speak with any objectivity to the work in the show, which I used as inspiration for writing. But I can talk about what it?s like to work on an artist?s book as someone with no background in the language of visual research and practice.

Since much of Heidi?s work uses language drawn from nature, I found myself drawn to writing about her show in the form of a natural history, and in brief talks? Heidi would declare herself interested in erosion, and I would announce I wanted to include a description of the Driftless Area in the American Midwest, where the ACRE residency in Steuben is located?we came to a consensus regarding what the chapters of the book should be about. All the sections of the resulting artist book related in some way to the natural world that framed and grounded (so to speak) Heidi?s practice while making the work: glaciation and driftlessness; a guide to the artist in her studio framed as an ethnographic study; reasons for people to cut into the earth objectively listed; identifying weeds as an epistemic undertaking; erosion; archaeology.

We even agreed on a format for the field guide: appropriated record boxes with field samples of the materials that were important for her work placed in compartments built into the boxes, and the text of the field guide inserted as loose pages inside.

Then all that was left for me was to write the text itself. The process of writing an artist?s book, unlike that of criticism, academic research, or general cocktail party conversation, involves not straightforward (even sensitively straightforward) analysis but the actual creation (a kind of semiotic and material/visual excess) of metaphors for others to break down and analyze?a necessarily not overdetermined argument combining and utilizing the show?s visual language. And not only that, but Heidi wanted the book to be part of the show (a kind of sculpture, almost, that would eventually become literally fused to another work in the show by being embedded in a river of melted wax). The book also had to be an object of visual interest? as a critic, this pressure was new and immense for me.

To say the least, I had to shift rhetorical strategies in my own practice to write a piece intended to be a work of art itself. Heidi and I worked well enough together?I think ultimately we both ended up with a piece we were proud of? but I?ve never felt so strongly that I was speaking a dialect of English completely misunderstood by other people. Heidi would ask me questions about visual layout that I would be completely unable to answer. I would write something about the platform pieces in the show that she thought were too obvious (for example, I would overstate the case by arguing what certain wooden platforms signified in the exhibit, as opposed to what they weren?t; we ended up beginning the chapter about the platforms with the line ?The platform is neither one thing or another,? which is also true of the resulting book, entitled Art in the Earth: A field guide from the soil to the studio). I would frown confusedly at my computer screen when she suggested over email that we make up our own lexicon of what various plants mean.

It?s not that I?m completely uncreative; it?s that critics are taught to think in tight associative circles based on the language suggested by artists in their work, which in turn undermines us when we attempt to dialogue with the expansive thoughts of artists while they are creating, as Heidi was while in dialogue with me. This tension between creative and critical (for example: I wanted to say what the form of the platform in the show meant; Heidi was sure we should just say what it didn?t mean) is the stuff of cliche precisely because it?s part of a very real negotation that happens when you write about art from either direction, and you?re only fully aware of it when on the other side (the side where most of the work is done).

The fact that the artist book ended up taking the form of a field guide?a prescription for seeing that?s not unlike criticism?added another layer of irony. Now, my favorite section from the book is the second of five listed ?reasons to cut into the earth:?

?To see what?s growing underneath: she dug holes into the earth all summer, her hair tied up in a bandana. She built a studio in the woods, using the holes she dug as molds into which she poured colored wax, capturing flowers, insects, and weeds in the viscous bright liquid. (When big chunks of glaciers get stuck in earth, they create giant pools of ice that result in holes when they melt. Geologists call these holes ?kettles,? and lakes often form in these depressions.) When she was a young girl in West Virginia and Maryland, she dug holes to explore the parts of the world that were just barely invisible but still attainable to her. The work that she did digging those holes was unprofessionalized and undifferentiated. She could have been looking for fossils or diamonds or evidence of human history before her.?

Installation view of Reasons to Cut Into the Earth, with photograph of Heidi Norton by Eileen Muller. Photograph of exhibition by Melissa Fischer.

I love this chunk of text because it?s a melting blend of genres and true to Heidi?s practice, and also because it opens up the possibilities for both the text and hopefully writing about the show. The best writing about art bridges the gaps between the creative and the critical and meets art on its own terms (another cliche because it?s true). As a critic, I rarely get a chance (or challenge myself) to do that; as a collaborator with an artist, it was required.

I?m starting to think an experience with this sort of work should be a rite of passage to arts criticism of any kind. It might also help us realize that the movement of the earth is not limited to soil, rocks, and plants:

?That everything is gradually destroyed does not have to be a realization that leads to despair. Photographs are like bodies; they fade away. This makes it more necessary for us to really look at them. The human body itself erodes. Erosion is naturally and certainly not always bad. We use it in everyday speech to talk about the way that things level out, or mutate in a natural, organic way into something else.? ~ Monica Westin and Heidi Norton

Heidi Norton?s exhibition Reasons to Cut Into the Earth runs until January 29 at Johalla Projects.?

Probe lifts veil on universe’s brightest blasts

Astronomers are closer than ever to understanding the brightest explosions in the sky, thanks to a NASA space telescope that sees the most energetic kind of light.

These bright flashes are gamma-ray bursts, and they occur when a big star dies and collapses in on itself to become an incredibly dense, incredibly small ball of matter called a black hole. As the star falls in, it expels its outer layer in a supernova, resulting in a bright release of light outward in all directions.

      As John Glenn, the world’s most enduring and endearing spaceman, celebrates a milestone that no other living astronaut has experienced ? the 50th anniversary of his own spaceflight ? he finds himself in overdrive reflecting on what has been an undeniably charmed life.

But sometimes an even brighter flash of light comes when the black hole, which is rotating very fast, sucks in matter and releases a thin jet of high-energy, high-speed radiation.

“The black hole is rotating rapidly, and as it is swallowing the matter from the star, the rotation ejects a jet of material through the supernova envelope,” Pennsylvania State University astronomer P?ter M?sz?ros said here Saturday at the annual meeting of the American Association for the Advancement of Science. [Photos: Black Holes of the Universe]

This gamma-ray burst temporarily becomes the most luminous thing in the universe.

To spot these brief spectacles, astronomers are taking advantage of the Fermi Gamma-Ray Space Telescope, which was launched in 2008 on a mission to observe gamma rays, the highest-energy form of light.

“Fermi is lucky to measure the highest-energy portion of the gamma-ray burst emission, which last for hundreds to thousands of seconds ? maybe 20 minutes,” M?sz?ros said in a statement.

These jets of radiation move extremely fast, basically at the speed of light, which is generally thought to represent the ultimate cosmic speed limit. However, researchers would like to know the jets’ speeds more precisely to further refine their theories.

“Fermi has done much better in measuring how close to the speed of light the jet gets,” M?sz?ros said. “But we still don’t know if it is 99.9995 percent the speed of light or 99.99995 percent the speed of light.”

Though astronomers have a general handle on what causes a gamma-ray burst, many aspects of the process are shrouded in mystery. One particularly thorny aspect comes from the fact that the explosions, and the black holes at the heart of them, involve extremely large masses and very tiny spaces.

Scientists use two theories to understand these realms. Albert Einstein’s general theory of relativity covers things that are very large, such as huge masses. And the theory of quantum mechanics reigns over things that are very small, such as tiny dimensions. However, these two theories are incompatible with each other, and scientists don’t know how to reconcile them.

“We have been able to rule out the simplest version of theories which combine quantum mechanics with gravity, although others remain to be tested,” M?sz?ros said.

The researchers hope that with more observational data from Fermi and other instruments, they will be better able to refine the theories that describe gamma-ray bursts and other extreme occurrences in the universe.
