Investing in stocks is an art, not a science, and people who've been trained to rigidly quantify everything have a big disadvantage.

When even the analysts are bored, it's time to start buying.

There are substantial rewards for adopting a regular routine of investing and following it no matter what, and additional rewards for buying more shares when most investors are scared into selling.

The biggest winners are surprises to me, and takeovers are even more surprising. It takes years, not months, to produce big results.

In the long run, a portfolio of well chosen stocks and/or equity mutual funds will always outperform a portfolio of bonds or a money-market account. In the long run, a portfolio of poorly chosen stocks won't outperform the money left under the mattress.

The simpler it is, the better I like it.

When stocks are attractive, you buy them. Sure, they can go lower. I've bought stocks at $12 that went to $2, but then they later went to $30. You just don't know when you can find the bottom.
