Westheimer, 81, is a veteran stockbroker who appears frequently on PBS’s Wall Street Week with Louis Rukeyser. In this guide, he presents clearly his straightforward investing advice–try to save 10% of your income; use mutual funds for diversification; etc. Although you may have heard much of this before, it’s handy to have it collected succinctly in one place. Sometimes Westheimer gets his facts wrong (Money Line with Lou Dobbs is on CNN, not CNBC), and his book is digressive at times, padding the advice with reminiscences and descriptions of what a broker does. Yet for those interested in a nontechnical introduction to investing from a pro, this is a good place to start. Photos.
