One up on wall street by Peter Lynch.

1) Know what you own, and know why you own it.

2) Selling your winners and holding your losers is like cutting the flowers and watering the weeds.

3) Owning stocks is like having children - don't get involved with more than you handle.

4) In dieting and in stocks, it is the gut and not the head that determines the results.

5) Remember, things are never clear until it's too late.

6) Big companies have small moves, small companies have big moves.

7) When you sell in desperation, you always sell cheap.

Common stocks uncommon profits by Philip Fisher.

1) If the job has been correctly done when a common stock is purchased, the time to sell it is - almost never.

2) Usually a very long list of securities is not a sign of the brilliant investor, but of one who is unsure of himself

3) Take extreme care to own not the most, but the best.

4) Don’t be Influenced by What Doesn’t Matter.

5) In the field of common stocks, a little bit of a great many can never be more than a poor substitute for a few of the outstanding.
