Goldman just launched the a mutual fund based on the Absolute Tracker Index (ART) Symbols GARTX, GCRTX, GRRTX, GSRTX, GJRTX.

Brochure here.

I have always been curious about the hedge fund indexes. Isn’t beta the one part of hedge funds you don’t want? I bet a simple allocation equally weighted of US Stocks, Foreign Stocks, Bonds, REITs, and Commodities performs better (especially after the 1.6% fee). Some of the share classes have loads as high as 5% (and why anyone would buy a load fund is beyond me).

It is always nice to see a model continue to perform out-of-sample. Below are the results of the “Quant Approach to TAA” paper since it left off in 2005. Equity-like returns with bond-like volatility and low drawdowns. Obviously much of this outperformance is due to the spectacular run in commodities and the (relatively) high allocation this model uses at 20% of the portfolio. This does not include June and the additional 5% dump in the S&P500. One could use five simple ETFs to replicate the asset classes mentioned in the paper (VTI or SPY, VEU or EFA, BND or AGG, VNQ or IYR, and DBC or GSG).

Doggy Dogs

I’m not much of a ranter, but it doesn’t make any sense to me to continue to focus on dividends when there has clearly been a structural change in the market (that happened way back in 1982). (For newer readers there is background reading with lots of links at the end.)

Dogs of the Dow is simply to top ten stocks in the Dow sorted by dividend yield.
Flying Five further sorts those by lowest price.
Net Payout yield is the top ten Dow stocks sorted by net payout yield.

For the past 30 years or so the Dogs strategy has outperformed the DOW by ~ 3% per annum, and the Net Payout Yield strategy another 3% on top of that (ditto for Flying Five). All underperformed the Dow in 2007 but had monster years in 2006.

2008 is shaping up to be potentially the worst on record since 1972 for the Dogs and Flying Five strategies. Previous worst years are -8% and -15% respectively. Payout Yield is doing much better:

Dow: -10%
Dogs: -15%
Flying Five: -22%
Payout Yield: -6%

You can find the current payout yield stocks here. The top 10 right now are:

Sharpe Ratios of Managers

The Sharpe Ratio is a measure of the risk-adjusted return of an investment. While there are a lot of ways to measure risk, the Sharpe Ratio uses the volatility as measured by the standard deviation of returns. Originally developed by Stanford Professor William Sharpe, it is simply the return of an investment (R) minus cash sitting in T-bills (otherwise knows and the risk free rate, Rf), divided by the volatility of the investment (σ). Cash will have a Sharpe Ratio of zero.

S= (R – Rf) / σ

A good rule of thumb for Sharpe ratios is that asset classes, over the long term, have Sharpe’s around .2 to .3. A “dummy” 60/40 allocation to stocks/bonds is around .4. A good all-weather allocation is around .6. However, over shorter periods the numbers can bounce all over the place. From 1900-2007, the S&P 500 has had Sharpe Ratios per decade ranging from -.08 (the 1970s) to 1.4 (the 1950s). If you want more info on the Sharpe Ratio, Bob Fulks has a great piece here.

One of the problems with the Sharpe Ratio is that it “penalizes” upside volatility. An investor likes volatility to the upside, but dislikes volatility to the downside.

Here is a good PowerPoint that shows some historical Sharpe Ratios for some very successful managers. (It is excerpted from the book Scenarios for Risk Management and Global Investment Strategies ). Ziemba’s point is that managers should not be penalized for upside volatility, only for their losses. So even though Berkshire did almost 25% a year over this time period, it has a lower Sharpe than the S&P500 that returned only 18%. (Great Ziemba PDF here.)

The Symmetric Downside-Risk Sharpe Ratio (Digest Summary)
William T. Ziemba
Journal of Portfolio Management, Vol. 32, No. 1: 108-122

Vanguard Windsor Fund – Managed by John Neff for 30 years, this fund was regularly in the top 5% of all mutual funds.
Berkshire Hathaway – Warren Buffett’s conglomerate holding company has returned over 20% for the past forty years.
Quantum Fund – George Soros co-managed this fund with Jim Rogers, and it returned over 40% a year in the 1970s. From 1969 to 2001 he did over 30% per year.
Tiger Management – Managed by Julian Robertson.
The Ford Foundation – One of the top performing foundations.

The first observation is how outstanding the returns were for stocks in this period, which inflates the Sharpe Ratio for the S&P 500 to one of the highest levels it has seen in the past century. The second observation is that many of these successful managers are getting penalized for making money with their upside volatility.

To gain a full understanding of a manager’s performance investors should use alternative metrics to evaluate managers. Some alternate metrics include:

Sortino Ratio: uses the volatility of negative asset returns in the denominator (similar to Ziemba’s downside symmetric Sharpe Ratio)
Sterling Ratio: uses the average max drawdown in the denominator
MAR (or Calmar) Ratio: uses max drawdown in the denominator
Ulcer index: Measures the length and severity of drawdowns.

The average return and volatility can tell you a lot, but if you really want to get nerdy check out the third and fourth momements of the return distribution, skew and kurtosis. Check out the white paper “Skewing Your Diversification” by Mark Shore.

Non-linear strategies like option selling can artificially inflate the Sharpe Ratio as they have incredibly consistent good performance until they don’t (which is usually a huge or total blowup ala LTCM).

Below is a chart from fund manager Bob Fulks who shows how an asset can have varying Sharpe Ratios depending on the time period.

Princeton-Newport is one of the best performing hedge funds of all time, and for a good review check out the great book Fortune’s Formula(more in the next post). 15% per year for 20 years and 3 down months is a pretty enviable track record.

Thorp has a chapter in The Best of Wilmott, and you can actually download the PDF for free here: “Models for Beating the Market“.

A new managed futures ETN hits the market (LSC). As I predicted in an earlier article in mid-07, this ETN cuts the fees in half from the Rydex fund (RYMFX) down to 0.75%. Direxion is also launching a mutual fund on the sister version of the DTI, the CTI (which exclusively invests in commodity futures).

When Markets Collide


I just read El-Erian’s new book When Markets Collide this past weekend.

Am I the only person to notice that his allocation only adds up to 98%? Weird. (I just added 2% to cash.) I did like this quote from the book which reminded me of my post a couple months ago on optimizing happiness:

“There is growing talk about the importance of reducing noise lest it adversely impact quality-of-life indicators.”

Anyway, below are the allocations of the Harvard and Yale Endowments vs. El-Erian’s recommended allocation. As you can see, it is a fairly similar allocation to the Harvard endowment, with a little more in foreign bonds and no allocation to hedge funds. I lumped infrastructure in with real estate so that it could be compared to the endowments on an apples-to-apples basis.

Following that is a comparison if you back out the private equity and hedge fund allocations. Special situations was lumped into cash. He described them as:

“investment opportunities that are attractive but do not fit comfortably into the categories I have covered so far…they usually relate to two types of activities: new longer-term activities that are supported by a secular hypothesis but are yet to gain broad-based acceptance; and shorter-term activities that materialize due to sharp dislocations that involve significant overshoots.”

This seems to be somewhat of a subjective recomendation and not all that useful for the retail investor. He mentioned water, agriculture, and carbon credits as three areas for the longer-term secular activities.

The expected return is right in line with the endowment allocation I mentioned in my paper, or roughly a 1:1 return to volatility ratio (about 10% return with 10% volatility and 20% drawdown over time).

Asset Allocation vs. Interest Rates

I created a Google Custom Search Gadget and added it to the World Beta toolbar. It searches only the top 50 investment blogs. Let me know what you think (and if I should add some more blogs). You can also find the search site here where you can customize the gadget or add it to your Google homepage or blog.

While oil is gushing to the moon today I re-read this great PowerPoint from Edward Qian at PanAgora – Multiple Alpha Sources and Risk Management. In the presentation they have a slide that shows asset class returns broken into Fed tightening and easing periods.

I thought it would be interesting to take the five asset classes mentioned in my paper and recreate the study with data going back further to 1973. Each month I recorded the year over year change in interest rates, and then the next month returns for the asset classes. For example, if interest rates declined from 5% to 4% then that would be considered a Fed easing bucket. While any number of interest rates could be used, I simply used T-Bills (and I know T-bills don’t equal fed funds but it should be close being at the short end). Below is the chart for all months from 1973-2007. In periods of fed easing, stocks, foreign stocks, bonds and REITs all performed better which makes intuitive sense because they are all capital assets and benefit from lower interest rates. Commodities on the other hand, turn in twice the returns when interest rates are going up, which makes sense due to their correlation with inflation and unexpected inflation. A simple model would be to alter portfolio weightings based on trend in interest rates. Capital assets (stocks, bonds, REITs) should have a higher percent allocation when interest rates are going down, and ditto for commodities when interest rates are going up. If I get around to it I’ll report some portfolio performance numbers for this strategy.

The red dots are Fed Tightening periods, and the blue dots are Fed Easing periods. Click on the chart to zoom in.
