Buffett's advice for Investors

For someone who is an active investor:
You don't want investors to think that what they read today is important in terms of their investment strategy. Their investment strategy should factor in that (a) if you knew what was going to happen in the economy, you still wouldn't necessarily know what was going to happen in the stock market. And (b) they can't pick stocks that are better than average. Stocks are a good thing to own over time. There's only two things you can do wrong: You can buy the wrong ones, and you can buy or sell them at the wrong time. And the truth is you never need to sell them, basically. You just make sure you own a cross section of American industry. Then they just have to worry about getting greedy. You know, I always say you should get greedy when others are fearful and fearful when others are greedy. But that's too much to expect. Of course, you shouldn't get greedy when others get greedy and fearful when others get fearful. At a minimum, try to stay away from that.

For someone who is not an active investor:
If they're not going to be an active investor - and very few should try to do that - then they should just stay with index funds. Any low-cost index fund. And they should buy it over time. They're not going to be able to pick the right price and the right time. What they want to do is avoid the wrong price and wrong stock. You just make sure you own a piece of American business, and you don't buy all at one time.
