Charles Biderman, founder and CEO of TrimTabs, has developed a proprietary investment strategy based upon investor behavior and supply and demand between buyers and sellers in the U.S. stock market, using 21 factors in evaluating market movements. This strategy is used by dozens of Hedge Funds and many large institutions, and is now available to the private investor. This former Harvard M.B.A. has created a very interesting set of metrics to read the market’s demand and supply of buyers and sellers. Any investor will find this to be very interesting. At the date of this recording, some Partnervest Advisory Services client accounts had an ownership position in TTFS, an AdvisorShares ETF subadvised by TrimTabs and discussed in this interview.
