The market is like an incredibly skilled teacher, much more reliable than those speculative funds. Those speculative funds are also 'taught' by the market. If the market conditions are poor and you don't cut your losses, you'll end up losing even more the next day.

If the market is good and you're still timid, only daring to place small bets, then you definitely won't make much money. We need to follow the market, taking profits when we should and cutting losses when we need to; that's for sure!
