NOT How to Create Your Own Hedge Fund

The WSJ had a peculiar article about how to use ETFs to "create your own hedge fund." The article isolated several hedge strategies, some recent performance data of these strategies at a broader index level and offered ETF combos to serve as proxies that would have delivered the same results for much less in the way of fees.

The suggested hedge fund replicating ETF combos came from research done by William Bernstein who concluded that hedge funds can be mimicked with "varying amounts of just two ETFs, plus cash."

The two ETFs that Bernstein used for this were the iShares Russell 3000 Growth Fund (IWZ) and the Vanguard Russell 3000 ETF (VTHR)--so a total market fund of sorts and the growth slice of the total market. So to capture equity, relative value, event driven or macro hedge fund performance (the four categories cited in the article) all that needs to be done is combine the two funds and cash in different percentages. The article was not clear on the amount of time that was analyzed to draw these conclusions but there was a reference to how one of the combos did over the last two years.

The last time I looked at the article there was only one comment and it called the portfolios ridiculous.

Since the March 2009 low, hedge funds have broadly lagged the S&P 500 which the article attributes to hedge fund managers being too bearish (or skeptical?) for the last three and a half years. So, stated another way the various hedge strategies have lagged for being too bearish. One flaw in the article is that they did not set out to lag the S&P 500.

So equity hedge funds were up 6.3% annualized for the last two years which Bernstein says could have been equaled by putting 38% into IWZ, 16% into VTHR and the remaining 46% in cash. If the article is about how to mimic hedge funds then there is a huge (and ridiculous) assumption that equity hedge funds will continue to track the same as the the two ETFs held in those percentages. What this article seems to offer is a backward looking coincidence and investing this way going forward is to assume the same coincidence will persist.

From a mimic the hedge funds standpoint, the article is worthless. Perhaps there is an argument to be made for the equity portion of a broad based portfolio to be split in some fashion between all cap and all cap growth (although I would not be the one to make it) but that is not what the article is about.

I do believe that the article is an attempt to teach newer investors something about portfolio construction but that it simply is a bad article. The reason to write about this at all is that the country has a problem with financial literacy and articles like this will not help to solve the problem. As I have mentioned before it is likely that you reading this blog (along with other blogs) are probably the person that close friends and family members go to when they have investing questions and you probably want to help them in some capacity. Steering them away from dreck like the above linked article can help solve the problem.


Unrelated, we watched The Bourne Legacy this weekend. Over the years we've had fun with the possible contents of Jason Bourne's safety deposit box in the Swiss bank from the first film in the series. The main character in Legacy was Aaron Cross played by Jeremy Renner. Cross' safety deposit box equivalent was inside a car door (couldn't find a picture so I included Bourne's safety deposit box instead) and contained cash and a new item that Bourne did not have; a bunch of license plates which would clearly come in handy in several different scenarios.

I thought it was clever that the story in Legacy occurred simultaneously as the story from the Bourne Ultimatum which was the last of the three Matt Damon movies. Other than the car door fun and the coincident timeline there was very little good to say about the movie. There were unanswered questions and loops that were never closed.

If you have read any of Bernstein's material, you would know that he would NEVER recommend the approach in real life. This was an academic exercise illustrating his belief that portfolio returns can be largely explained (up to 80%) by the Fama and French's three factor model and further that hedge funds' compensation structure further reduces take home returns.

The real point of the article is that hedge funds are no panacea.

I think your blog post is a distortion of the theme of the article. Perhaps Mr. Bernstien was selected for this analysis due to his recently released e-book aimed at institutional portfolio managers.

Your bias against academic finance is once again on full display.

If the article was intended in the context you suggest then it was an even worse article that I thought.

Depending on your meaning of academic, bias is not a strong enough word.

Wall Street Journal? What else one would expect from "Murdoch Sewage Inc.?

Your comments on the article Roger are spot on!

While the article is pretty terrible, it touches on an important point: a lot of hedge funds get paid for just taking on beta. The trend of the last years has seen the average correlation coefficient between hedge fund and S&P500 returns go from around .3 to over .8, which is patently ridiculous for what is supposed to be an "alternative" asset class.

The article doesn't seem to be a Bernstein idea. It seems to be sprinkled with a Bernstein quote here and there to give it creedence or something.

Adam Savage of Mythbusters collects movie props and has attempted to re-create Bourne's go bag:

Bernstein actually makes a comment on the article in this Boglehead forum discussion

It's worth reading the bogllehead link. Thanks, Steve.

Roger, you were way off base on this one.

My neighbor is a hedge fund manager. He is always right; yes, he will argue that black is really white. Whenever I ask how his fund is doing, he says they are doing fine, they have a positive return, which is their benchmark; they don't measure against an index, just have to have a return greater than zero. Ok, don't need to invest in a hedge fund to do that; and you can see in Bernstein's responses, he is pointing that you can replicate hedge fund performance without tying up your invested capital ... not that you would want to replicate hedge fund performance.
