指値(limit order)を使え！という教え
There are plenty of opportunities out there. If one gets away, move on to the next one. A rather terse woman I know has this to say about life: “Never chase a man, a bus, or a stock. There will be another one along in five minutes.” The man I don’t know about, and bus availability varies from city to city, but she’s right about the stock. There are so many good ones day after day that there’s never a reason to be upset about an opportunity lost. It’s better to lose an opportunity than to lose money. So decide in advance what price is attractive to you and spell it out on a limit order.

この後さらに、成行き(market orders)はやめとけ、という教え。
Should you ever use market orders? Sure. There are times when you stumble on something that you think is so hot that it’s not coming down for years. A limit order specifying a lower price than the current one might miss the chance to buy this rising star. I would caution you about jumping on something instantaneously, though. I’ve discovered over the years that what’s a good buy today is usually still a good buy next week. The market moves around, but not as quickly as you might think. Emotions move a lot faster than the market. They also move faster than intelligent thoughts. So give the rational part of your brain time to catch up to the excited, frothy part. Never forget the power of clear thinking, predetermined prices, and the limit order.
