Founded in 1990, TrimTabs Investment Research is the leading independent institutional research firm focused on the supply and demand of shares of stock and the money available for investment. Our key premise – which we term Liquidity Theory – is that stock prices are a function of liquidity rather than value. Like the prices of any tradable good, the prices of stocks are driven primarily by supply and demand.
Unlike most quantitative stock-evaluation models, which focus on easily available price, volume, and earnings data, Liquidity Theory insights depend on detailed data on asset flows and how they shift over time. Since data on the supply and demand for stocks is scattered across so many sources, most strategies ignore stock market liquidity altogether.
By maintaining detailed quantitative models that track key areas of market liquidity and changes in the supply and demand for equities and equity-like vehicles, TrimTabs provides our clients with comprehensive real-time analysis of all aspects of equity-market liquidity.
On the supply side, we measure changes in the float of shares by aggregating corporate actions. On the demand side, we track the money moving into and out of the stock market by measuring the flows into and out of mutual funds, exchange-traded funds, and hedge funds. To obtain an early edge on future liquidity trends, our Real Time Macro research focuses on real-time measures of consumer income and employment.
