The worst thing you can do is invest in companies you know nothing about. Unfortunately, buying stocks on ignorance is still a popular American pastime.
Peter LynchThere's no shame in losing money on a stock. Everybody does it. What is shameful is to hold on to a stock, or worse, to buy more of it when the fundamentals are deteriorating.
Peter LynchA price drop in a good stock is only a tragedy if you sell at that price and never buy more. To me, a price drop is an opportunity to load up on bargains from among your worst performers and your laggards that show promise. If you can't convince yourself "When I'm down 25 percent, I'm a buyer" and banish forever the fatal thought "When I'm down 25 percent, I'm a seller," then you'll never make a decent profit in stocks.
