Google Finance offers only rudimentary financial market information. Users can create watchlists and get stock quotes. Content on the site comes from other sources and offers more opinion than insight. Delayed stock quotes and basic company information is available. An investor can't perform any meaningful research using the site.
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.
