Read fm 林少陽's most recent book, he says by statistics, the percentage of gain fm mental retarded is bigger than normal people. And also fm Soros' book, he assumed the market was not efficiently running.
It maybe wrong to think the stock market is a reasonable market. If not, the Nobel price winners in economic should be the richest men in the world.
So I don't surprise that abnormal investors can do better than reasonable investors.
