Timing and luck
Are successful people right, lucky or both?
In the mid-1980s, I listened to Nobel prize-winning finance professor, William Sharpe, address the Hong Kong Society of Securities Analysts.
Sharpe was one of our heroes, having developed the Capital Asset Pricing Model, or CAPM. (We don’t need to go into that here but for investment geeks CAPM is up there with sex).
Then the professor told us it was impossible to consistently beat the market.
