One opportunity this stay-at-home quarantine has afforded us, sad as it may sound to some, is increased time to work through the pile of academic papers on quantitative finance. It is amazing how much great stuff is out there. When you come across one that happens to be right in your wheel house and makes the case in a MUCH smarter sounding way than we ever can, all to the better. Such as it was with this recent piece – When it pays to follow the crowd: Strategy conformity and CTA performance by Nicolas Bollen, Mark Hutchinson and John O’Brien from Vanderbilt University and University College Cork.
The authors find that contrary to other areas of fund management in hedge funds and mutual funds, where being different is a positive trait (research on active share in the equity space is informative – see here), when it comes to CTAs/Managed Futures being a purist is the right approach. The authors analyzed the data using two different methods. First they sort funds into style groupings and calculate a Strategy Distinctiveness Index – funds that have low correlations to the style. They then look at the performance of portfolios of funds based on the SDI score. Second, they empirically check by rebuilding a simple model for standard trend following and regress funds against that model. Closer to pure trend the better.
The temptation is strong. The strategy you have used for years has underperformed. Why take the risk? Move back to the benchmark. Like a remake of a classic film, we have seen most of this before. In early 2009, pressure was on value stock managers to change their stripes. We recall a conversation from April 2009 with a foundation client invested in our Large Cap Value strategy. We had recently rolled to a new portfolio, and one of the selections was Wyndham Hotels. They were quite agitated – after the financial crisis it was unlikely that people would be going back to hotels for years. How could we? I took the quant’s way out of the question – “the model made me do it.” Wyndham was the best performing stock in the S&P 500 over the next 12 months.
The current reckoning certainly rhymes with the financial crisis. We must confess that even our conviction was challenged this time, and I promise you, ours runs deeper than most. Last week it was time to roll our value portfolio forward. Put the names back into the hat, take a fresh look, buy what is cheapest based on the models and caveats we employ. To add to the insult, it was also time to rebalance our multi-asset portfolios. What this meant was we had to buy a portfolio of decimated value names, in some cases buy more of them. Alaska Air? Kohl’s? Valero? MGM? Who is going to fly, go to a department store, get gas or gamble? Sure, these stocks have never really been cheaper, but come on. This is wake up in the middle of the night with these ticker symbols swirling in your head stuff. And you want us to buy more!
