Their problem is not earning money to fund their retirement dreams. Both Maggie and Sam are smart and successful: She is a heart surgeon and he is a well-heeled attorney. Yet they?ve lost a fortune, and they can see that no matter how much they earn, it can?t possibly offset the damage done by listening to the advice of their broker, so they?ve turned to me to stop the bleeding.

These two aren?t the only intelligent, affluent investors I?ve met who are frustrated and frightened by their investment results, and 2000 wasn?t the only bear market investors had to face. Based on 60 years of evidence, a bear market ravages investors every 3.3 years, and the average loss is 27%. That?s enough to scare anyone. According to AARP, 35% of all retirees go back to work after they retire. Could it be because the market cracks and scrambles their nest eggs?

I?m reminded of my Uncle Jim, who wouldn?t listen to me and retired in 1999 with $700,000. His plan was to create income from his retirement package and to live happily ever after. Interest rates were too low for Jim, so he decided to invest in growth mutual funds to create the income he wanted. By the end of 2002, his $700,000 had dropped to less than $400,000 thanks to an inhospitable market. His savings had lost 43% of its value. Then, instead of $700,000 working for him, he had $400,000 working for him. That meant less income--a lot less income. Faced with this disturbing reality, Jim sold his beautiful home to buy a small condo and had to go back to work. Jim didn?t have 70 years to ?think long-term? as his broker and other financial ?experts? suggested he should. Jim needed that income today.

What can Jim, Sam, Maggie and everyone else do to protect themselves from catastrophic loss in the future? Since we know that a crash comes every 3.3 years on average and the typical loss is over 27%, it is critical for investors to invest only when the risks of doing so are relatively low.

Of course whenever you invest in the stock market you take on risk. However, we know that certain times are riskier than others. Just as you check the weather forecast before you embark on a road trip, I?m suggesting that you check the market?s temperature before you hit the financial road.

There are a number of ways you can do this. The method I like best is watching the major indices, such as the Dow, S&P 500 and the NASDQ. Here are the specific steps:

1. I look for days when the volume explodes. For example, if the DOW trades 2 billion shares on average, and today the DOW trades 2.2 billion shares, that is a significant increase in shares.

2. When that happens, I pay attention to what happens to the price of the index. Continuing our example, if the DOW closes higher today to boot, I know that large institutions are falling over themselves trying to buy shares, which means prices are moving up.

3. We know that one sign of a healthy market is a big increase in shares traded, coupled with the index moving higher. In fact, there has never been a bull market stampede without a big increase in trading along with an increase in the index price. If I see two or more of these strong days, I?m more prone to invest.

I strongly suggest that you watch the major indices for clues on the market?s health before you invest. I?ll be providing more specific tips on how you can ?take the market?s temperature? next month, most notably how you know when it?s time to stop holding and sell.
