There was a time when the local stock market was the domain of only a handful of broker-investors who made handsome returns. The rest could only envy them. In the past two decades, though, the industry has grown dramatically with hundreds of broking firms springing up and thousands of analysts, fund managers and wealth advisors joining the fray. With almost every major global investor present in India — directly or indirectly — analysts, too, use the same copybook to analyse and value stocks. Information dissemination has improved dramatically, although that is not to say asymmetry is a thing of the past. When you combine a smart bunch of people with privileged access to information and better analysis, the result is a group fairly high on the skill threshold. Now, as the difference in skills is not as wide as it was earlier, Mauboussin’s theory comes into the picture. Luck perhaps begins to play a more important role in determining returns.
