TrimTabs Investing introduces a well-researched, market-proven technique to improve your investment returns by following the smart money in the stock market. While most stockbrokers and investment pundits claim that earnings drive stock prices, this groundbreaking book shows that what really makes stock prices rise or fall is liquidity — the number of shares trading and the amount of cash available to buy them.

In TrimTabs Investing, veteran investment consultant Charles Biderman details his completely original TrimTabs methodology. You will learn to:

Charles Biderman uses liquidity theory every day to generate market-beating returns for his clients, which include leading hedge fund and portfolio managers. From December 2000 through December 2004, when millions of individual investors saw their portfolios slashed by half or more, and the S&P 500 declined 8 percent, the TrimTabs model portfolio rose 148 percent. Whether you are an investment professional managing billions of dollars or an individual investor with a small nest egg, TrimTabs Investing shows you how to achieve similar results in your portfolio. It gives you the tools you need to beat the market averages with less risk by investing like the smart money in bull markets and bear markets alike.

Praise for TrimTabs Investing

"Charles Biderman, a savvy and battle-scarred veteran of the investment wars, has fashioned an intriguing approach to making money in the stock market that adroitly avoids both heavy-breathing speculation and the standard Wall Street practices that enable investors, big and small, to lose money in good markets as well as bad. Aimed at the sophisticated investor (which may or may not be an oxymoron), the book is written in blessedly straightforward prose and is a worthwhile read for anyone with an urge to have a fling at investing."
Alan Abelson
Barron's Financial Weekly

"Since the days of Joseph and Pharaoh, it has been axiomatic that the size of the grain harvest affects the level of grain prices; but today's investors have been slow to appreciate the fact that the supply of stock shares significantly determines the level of stock prices. Biderman's long overdue book outlines the theory and evidence behind 'Trading Float,' the actual-and exploitable-power behind major moves in the stock market."
Paul Montgomery
CEO and CIO of Montgomery Capital Management

"'Trade as corporate execs do, not as they say.' Charles Biderman has built an impressive list of hedge fund clients from this essential insight, and this book does a great job explaining exactly how retail investors can incorporate it into their investing."
Eric Zitzewitz
Assistant Professor of Economics, Stanford Graduate School of Business

"Charles Biderman is a smart thinker, clear writer — and he offers here some very interesting ideas. This book is for the little guy who enjoys reading about money and economics, even if he doesn't adopt the strategies offered here; and for the professional or sophisticated investor, who, to a greater or lesser degree, just might."
