Charles Biderman, born on October 24, 1946, is an American businessman and investor with a career spanning over five decades. He obtained a B.A. from Brooklyn College and an M.B.A. from Harvard Business School. His career began at Barron’s from 1971 to 1973, serving as Alan Abelson’s assistant. During this period, he identified and predicted the collapse of real estate investment trusts (REITs) in 1972, which influenced his investment approach focused on short-selling and real estate. By 1975, Biderman expanded his involvement in real estate, becoming a general partner in several limited partnerships that owned and managed over 1,000 apartments, office buildings in Dallas, Texas, and Memphis, Tennessee, and six strip shopping centers across Mississippi, Arkansas, Kentucky, and Tennessee.
In 1990, Biderman founded TrimTabs Investment Research and served as its CEO. The company specialized in tracking mutual funds and provided independent research with daily coverage of U.S. stock market liquidity, particularly during his leadership. This work led to the development of the Biderman Market Theory, which informed the company’s investment strategies. He authored ‘TrimTabs Investing: Using Liquidity Theory to Beat the Stock Market’ in 2005. His expertise led to regular interviews on CNBC and Bloomberg TV, and frequent mentions in financial publications such as Barron’s Magazine, The Wall Street Journal, Forbes, and Investor’s Business Daily.
Biderman further expanded his influence in asset management by launching the TrimTabs Float Shrink ETF (NYSE: TTFS) in 2011. This ETF earned a five-star Morningstar rating by March 31, 2016, with annualized returns of 19.22%, outperforming both the NASDAQ Buyback Achievers Index and the Russell 3000 Index. In 2016, TrimTabs launched another product, the TrimTabs U.S. Free Cash Flow Quality ETF (BATS: TTAC), which employed a similar strategy at a reduced expense ratio. TTAC demonstrated strong performance, returning 27.08% from November 2016 to December 2017. In 2018, Charles Biderman sold both TrimTabs Investment Research and the TrimTabs ETF asset management company.
