Book excerpt: In The Battle for Investment Survival, the turf is Wall Street, the goal is to preserve your capital at all costs, and to win is to "make a killing without being killed." This memorable classic, originally written in 1935, offers a fresh perspective on investing from times past. The Battle for Investment Survival treats investors to a straightforward account of how to profit-and how to avoid profit loss-in what Loeb would describe as the constant tug-of-war between rising and falling markets.
