StockTwits is an open, community-powered idea and information service for investments. Users can eavesdrop on traders and investors, or contribute to the conversation and build their reputation as savvy market wizards.
You need to log into the site with your Twitter details and you will be presented with a user interface filled with comments and stats showing the top ticker buzz, the top StockTwit talkers, and the top gainers and losers.
You have the ability to add stocks and save them to your own portfolio and limit the conversation around it to your most trusted sources. Another feature is the way the site aggregates ‘buzz’ and discussion around individual stocks. And it does it real-time because of the Twitter integration.
