Introduces the box theory and trailing stop discipline.
Nicolas Darvas was a professional ballroom dancer who traded American equities by cable from tour stops around the world between 1957 and 1959. He recounts his sequence of methods in order of failure: Canadian penny stocks bought on tips, then fundamental analysis based on earnings and industry reports, then a purely technical approach, and finally the combination he settled on. The book is unusual in giving the losing phases as much space as the winning one.
The method Darvas arrived at, which he called the box theory, works as follows. He watched for stocks whose volume rose sharply, tracked the price range within which each then oscillated, and treated that range as a box. He bought when the price broke above the top of a box on volume, placed a stop-loss just below the breakout point, and raised the stop as the stock established higher boxes. He restricted purchases to companies in industries he expected to produce new products or earnings surprises, which is why he described himself as a techno-fundamentalist. He held very few positions and let the stops remove him from losers.
The account is anecdotal and covers a single strong bull market in a narrow set of names, including Lorillard, Diners Club, E.L. Bruce and Universal Controls. There is no systematic test of the method here, though later momentum research has given qualified support to the underlying observation that stocks making new highs tend to continue. Darvas's specific rules, especially the reliance on stop-loss orders placed close to entry, work poorly in choppy markets and in illiquid securities. Read it for the psychology of position management rather than for a replicable system.
Traders and investors interested in the origins of trend-following and position-sizing discipline, and in a candid record of how a novice's methods failed before one worked.
