This is part of a series in which we re-evaluate Money Magazine’s “25 Rules To Grow Rich By”. One “rule” will be re-evaluated each weekday until the series concludes; you can keep tabs on the action at the 25 Rules index.
Rule #11: If you don’t understand how an investment works, don’t buy it.
The sheer hubris of the above statement is incredible. “Leave the real money makers to the experts; you go along and play with your savings account at your local bank, junior.” It’s typical of the attitude of many people in the financial sector as they try to play Prometheus, bringing the fire of financial knowledge from the gods of Wall Street.
The fact is that most investments are not all that complicated. If you are interested in a particular investment, pick up a book at your local library (or your local bookstore) and read about it. This is an opportunity to learn something that could be directly useful to your pocketbook, not an excuse to run for the hills like a coward.
