You never know your luck until you slide in it. The future does not resemble the past to any degree that is useful.
Some investors go through phases in which they appear to have mastered the market.
Warren Buffett is the obvious example. But I've a nagging suspicion that even the Sage of Omaha's 30-year track record owes more to blind luck than to his undoubted intelligence, decency and good line in folksy wisdom. Trying to guess what will happen next in financial markets is a good parlour game. As a hobby, it's on a par with greyhound racing or building matchwood replicas of the Mayflower. But don't expect to get rich by trying to time your investments, pick winning stocks or select fund managers with the Midas touch.
