Although the evidence is not unambiguous, reports of the death of the

Assuming efficient markets in economics is a bit like neglecting air resistance in physics. It allows developing beautiful models and using powerful mathematical techniques, but the simple fact that there is air everywhere around us (otherwise, we could not live) or that actual markets exhibit all kinds of imperfections is not enough to discard such ...

Discussions about market efficiency in finance are unfocused when they fail to distinguish between the price-equals-value market hypothesis and the hard-to-beat market hypothesis. And discussions are further lacking when they fail to explain why so many investors believe that markets are easy to beat when, in truth, they are hard to beat.
