As an older book for making money in the stock market, it is worth reading today for a few reasons. First, it reinforces the point that it is more important to avoid losses than to strive for gains. Darvas includes his rules for limiting losses. Second, this investing theory is oriented toward active, moving, growth stocks. With increasing volatility in the market, most stocks go through cycles, taking even many of the former value plays into a "growth cycle" arena for part of the year. Third, many people shy away from buying on margin, and maybe they should, but here is one philosophy for buying on margin that takes some of the risk out. This book would have been better if there were more details on what, how and when to do what is described. Other books since then have addressed these issues. One of the real problems that investors face is The Disbelief Stall: The idea that they won't really make money in the stock market. That leads to behaviors and bad decisions that reinforce that idea. Then based on those few experiences, they fall in to The Misconceptions Stall: That they may lose on each trade. That leads to The Procrastination Stall: Not getting out in time and incurring more losses. To learn more about these stalls that get in the way of being successful, you should also read THE 2,000 PERCENT SOLUTION. Books like HOW I MADE $2,000,000 IN THE STOCK MARKET, HOW TO MAKE MONEY IN STOCKS, and the new books on E-trading help to break The Communications Stall and explain what to do, how to do it, and which investing style is comfortable for you based on each individual's objectives.
