Wall Street brokerages are working hard these days to attract women investors. Publishers are, too. One of many recent titles on money management for women, Savvy Investing for Women is more informative than most. Marlene Jupiter, a former Wall Street derivatives trader, takes her subject and her readers seriously. The book provides a short course on economics, on portfolio diversification (jargon for "Don't put all your eggs in one basket"), and on the basics of buying stocks, bonds, and mutual funds. There's even a chapter on technical analysis, an abstruse topic neglected by most popular books but described by Jupiter with admirable clarity.
