Crumbling Limits
Although behavioral psychology has helped explain some of the odder effects around investment there remain many sceptics. The reason for this isn’t hard to find, because if you start out assuming that peculiar features of investment markets are caused by rampant misbehavior then you’re quite likely to find evidence to support that assumption.
Some of this is down to irrational behavior, no doubt, but perhaps not in the way that the academics first thought. So, for instance, consider the use of the humble limit order. Used unwisely – which is to say, nearly always – it doesn’t just lose investors money but ruins the researchers’ results into the bargain. Just watch those behavioral biases crumble away.
