I think one of the most neglected tools in investing is newsgroup. Why? Some people may believe that there are more gossips than useful news. However, this is not always the case. Newsgroup is an online group of people who intend to share their common interest and opinions on the internet. You can post all sorts of questions, crazy ideas, rebuttals, theories, rumours, and others that are related to a particular topic and let the others to respond to your posting or questions. Let’s say if you have a question about a recent stock movement of Apple’s shares, you may find dozens of second opinions on whether this is a good time to get into the market or throw off what you have in hands.
