The Weekly Liquidity Review is a publication that offers the broadest overview of the supply and demand dynamics of the U.S. stock market.

The investment flows include weekly updates that give investors short- and long-term trading signals based on the current and longer-term trends that TrimTabs observes in the U.S. and global stock markets.

The Weekly International Liquidity Review includes fund flow and sentiment indicators for the following countries/regions: China, Developed Emerging Markets, Europe, Japan, Latin America and Pacific Asia ex-Japan.

TrimTabs provides a assessment of the overall health of the U.S. economy by tracking wage and salary growth and employment growth based on real-time income tax withholdings data from the U.S. Treasury, credit indicators, unemployment claims, surveys of manufacturers and purchasing managers, and housing indicators.

Biderman developed TrimTabs into the only independent research firm that would provide people with detailed daily coverage of U.S. stock market liquidity.

The Fund seeks to achieve this objective by investing in stocks with liquidity and fundamental characteristics that are historically associated with superior long-term performance.

AdvisorShares replaced TrimTabs with Wilshire Associates, of Santa Monica, California, but offered no explanation for the change.

[citation needed] "This is insane", TrimTabs CEO Charles Biderman said of the firing, "They came up with no reason, no nothing.” Charles Biderman claimed that it was nearly impossible for Wilshire to replicate TrimTabs stock selection methodology and his first move after the firing was to open a separately managed account with a lower minimum investment and lower fees than TTFS.
