Bloomberg is an investment research platform only for those who can afford it. The Bloomberg service costs $25,000 per year. So it is effectively inaccessible to most investors. The company offers just one plan. Users can't pay a lower price to subscribe to only the data they need. The platform is also very complex and overwhelming, which makes it difficult to navigate and find data.

Yahoo Finance began by providing basic stock quotes and market information to individual investors. Today the site streams advertising-packed video nonstop. Its front page is populated with content taken from other sources and offers more opinion than insight. Delayed stock quotes and rudimentary company information is available, but deep fundamental research and data analytics are missing. Yahoo Finance has restricted many of its original features as it attempts to migrate users to a pay-to-play platform.
