Jason Goepfert has been trading stocks, options, futures, currencies and commodities for 20 years. In these jobs, he has developed several indicators based on in-house customer activity, and was immensely interested in how often extremes in the business coincided with turning points in the market. After he left the brokerage, Goepfert struggled to find a place where he could monitor similar indicators. To fill that need, he started a service that provided sentiment indicators and research in one spot, without having to search all over the web. Currently, SentimenTrader.com has subscribers in all 50 states and more than 50 foreign countries. Goepfert also provides private consulting for hedge funds and managed accounts.
