History TrimTabs was founded in 1990 by Charles Biderman in Santa Rosa, California as a company providing ideas to hedge funds for share exchange. His first recommendation was the selling of Midlantic Bank whose shares were trading between 25 and 30 dollars in January 1990. Lately, Midlantic Bank was acquired by another bank at a price below 10 dollars to avoid bankruptcy. Eventually, Biderman realized that nobody was regularly the money flow in and out of the U.S. stock market. He began to search real time data on the flow of money of any kind, including corporate transactions, the flow of investment funds and debt margin account marginal. Corporate America became a major buyer of shares in late 1994 and the flow of money coming into mutual funds accelerated in 1995.Biderman By then realized that the short selling of shares no longer worked because there was too much money flooding the U.S. market, coming from corporate America and individual investors. In August 1995, began to analyze the U.S. stock market liquidity in a newsletter then be entitled TrimTabs Weekly Liquidity Review. The inversion method is described in detail TrimTabs in TrimTabs Investing: Using Liquidity Theory to Beat the Stock Market (John Wiley Sons, 2005). TrimTabs has expanded its products available in recent years. In 2002 she released TrimTabs Weekly Macro Analysis that uses real-time economic indicators such as withholding taxes and job listings online to assess the health of the U.S. economy.
