Since Burton Malkiel's seminal work A Random Walk Down Wall Street was published, the financial world has swallowed whole the idea that market movement is chaotic and random. Richard Lehman, coauthor of New Insights in Covered Call Writing, uses behavior-based trend analysis to debunk that theory. He demonstrates that the market has discernible trends that are forseeable. By learning to spot those trends, traders and investors can predict market movements to boost returns in anything from equities to 401(k) accounts.
