Some perspective on ‘efficient markets’ from Elliott Management’s Paul Singer,
The fact that the vast majority of investors and traders cannot (with rare exceptions) beat the markets over long periods of time is not an argument for efficiency.Rather, the reason is that they are mostly doing the same thing sharing the same set of assumptions, and following the same impulses.
The fact that a basic assumption about the world is widely held does not make it true, nor does it make trading and pricing decisions based on that assumption efficient regardless of how liquid markets pricing in that assumption appear to be!
Certainly there are periods of time when some markets and submarkets appear to be efficient, but those who have vision, creativity and an understanding of the broader context of markets will make greater returns and/or attain a superior risk profile (assuming they do not get run over by standing rigidly against the sometimes-deeply false passions of the day expressed by the consensus).
How do the select few more or less continuously make money when the “efficient” markets are moving all over the place? Why do most investors fail, over long periods of time, to keep up with their desired index? And why do some people blow up? (more…)
