Consistent good returns
A comment above in relation to returns of 5-8% p.a. got me thinking. This is a thought experiment and I am in no way suggesting funds out there engage in the 'strategy' outlined below.
If we saw a fund delivering say 7% p.a. on a consistent basis, it would surely pique our interest?
Recently I priced a 1-year put option on the S&P500. The cost was just north of 7%. Expensive insurance right?
But what if I wanted to sell this insurance, instead of buying it? I could earn a return of 7% for selling this put option, i.e. protecting someone else's down side if the S&P500 declines in value over a 1 year time horizon. If the S&P500 doesn't decline, the put option expires worthless and the game is on again next year. I do the same again and again, until such time as the market declines. In which case I am on the hook for the total loss.
The returns on a fund using this strategy might look outstanding for a period of time and gather lots of assets. Nassim Taleb referred to a strategy like this as picking up the nickels in front of a steam roller. The expected value of the stratregy is (very much) less than zero, but this fact is camouflaged by the appearance of low risk and steady returns. Madoff comes to mind.
Long winded way of saying that we need to be very careful when looking at what might be a long track record of steady returns.
