some people should not own stocks at all, because they get too upset on the price fluctuations. If you are gonna do dumb things because your stock goes down you shouldn't own stocks at all.
The best thing with stocks, actually, is to buy them consistently over time.
You want to spread the risk as far as the specific companies you're in by owning a diversified group, and you diversify over time by buying this month, next month, the year after, the year after, the year after.
Investing is a long game, he says.
"I know what markets are going to do over a long period of time: They're going to go up. But in terms of what's going to happen in a day or a week or a month or a year even, I've never felt that I knew it and I've never felt that was important"
You're making a terrible mistake if you stay out of a game that you think is going to be very good over time because you think you can pick a better time to enter it.
He says,
“Be fearful when others are greedy, and greedy when others are fearful.”
You should avoid buying stocks because everyone else is buying. Instead, look for the stocks that few people are paying attention to, check their fundamentals, and invest if it makes sense.
