“I would be bum on the street with a tin cup if the markets were always efficient” Warrant Buffet

 Market Asymmetry is reality. 

Buffett's statement suggests that if markets were always efficient, meaning that all available information was accurately and instantly reflected in stock prices, there would be no opportunity for investors like him to find undervalued stocks and make profits. In such a scenario, he implies that his skills as an investor would be rendered useless, and he would have no choice but to rely on charity, metaphorically depicted as being a bum on the street with a tin cup.
