Our Story

The Hammerstone Group, based in Westport, CT, was founded over 14 years ago. Hammerstone has levered its collective knowledge of the financial industry to create a financial media product that allows its subscribers to gain an edge against the market. The Hammerstone Pro Feed is based on the idea that with access to timely news sources, investors have the ability to beat the market.

Since 2001, the Hammerstone Pro Feed has continued to grow to a subscriber base of over almost 1000 active members.

The Hammerstone Pro Feed was specifically developed for traders, active portfolio managers and other market participants. Members communicate and collaborate in real-time to discuss intra-day news, markets and securities. The Feed’s unique combination of real-time information flow provides a valuable solution for market participants seeking a constant stream of data generated from trading professionals, thus affording a true peer barometer on a minute by minute basis. Blogs, message boards and other online news sources only provide one way news flow in a delayed format, unlike the Hammerstone Feed which provides subscribers a real-time INTERACTIVE trading edge.
