Invest in vanity. Buy stocks in high-profile companies whose products are designed to make you feel good and look good.

Bet on black. Buy low-debt or no-debt companies. When the economy is in trouble, these companies usually have enough cash on hand to stay out of trouble. And they seldom need to borrow when interest rates are high.

The higher the yield, the higher the risk. A high yield is designed to attract investors. An outrageously high yield attracts fools.

If you're uncomfortable with your financial advisor, it's probably with good reason.

Sell before the holidays. Stock prices tend to rise on the last trading day before major holidays.

Never call your broker on Monday. Out of courtesy and common sense, wait until Tuesday. A good broker is focused on the opening of the market - at home and around the world - and on getting back into a business frame of mind after the weekend.

Avoid greed and fear. These are the investor's Achilles heels. Keeping all your money in the bank earning 3% interest is just as foolish as dumping your entire savings into the market thinking you'll make a quick buck.
