Social Media & Networking

Social media and networking sites are based on user participation and user-generated content. These sites allow users to exchange opinions, insights, experiences and perspectives with each other about individual securities, investment practices, etc. Social media can take many different forms, including Internet forums or message boards, weblogs (blogs), wikis (user-driven information centers) and podcasts.

 Motley Fool CAPS  

Registered users can post predictions of stock performance relative to the S&P 500 over a specified time period. As stock prices change, the site evaluates player predictions. Over time, players receive an accuracy percentage based on how often they make correct predictions. In addition, based on the performance of their picks, players receive a percentile rating indicating the percentage of players they are outperforming. Stocks also receive ratings, which are aggregations of every player prediction for that stock, indicating whether or not players think the stock will outperform the S&P 500. Players with higher ratings have more influence on stock ratings. CAPS screener allows users to screen for stocks with varying CAPS ratings as well as on financial data elements. Though there are competitive websites, CAPS remains the most popular of its kind.
