Managed futures is supposed to be a “profitable hedge” – long term positive returns with zero or negative correlation to the equity market. The recent coronavirus crisis highlights one of our core beliefs, namely that the construction of most managed futures portfolios diminishes that critical characteristic in two important ways. First, they include equity futures in the portfolio mix, and second, positions are adjusted for volatility. The combination of these two things is particularly deadly. There is nothing wrong with trend following equity futures. But anyone who watches the markets knows that equity vol is lowest at the TOP! That means that managers will have their largest equity positions at the TOP! Furthermore, when the market breaks, the eventual short position they take will be much, much smaller than the long they had at the top. In non-equity markets, the same can be true. In the recent virus break, crude was previously making new highs, then broke very sharply. Vol adjusted short positions will be tiny. Chart below compares a sampling of large blue-chip futures mutual funds with the MLM Index EV (15V) (which does not vol adjust).
It’s a question of conflicting goals. If you want to maximize Sharpe ratio as a standalone investment, then vol adjust. If the rest of your portfolio is full of stocks and credits already, and you want a “profitable hedge” to maximize total portfolio Sharpe ratio, don’t. (See this blog post for more technical detail).
