Welcome to Stockpickr! I'm very excited about this joint venture with TheStreet.com -- and I hope you'll be excited about it as a tool you can use to boost your trading performance.First, some quick background, and then some tips on how you can use it. Stockpickr started off as a tool I developed with colleagues to track our trading. We wanted a way to quickly see what the best hedge funds were in, and then what companies were potentially related to those stocks so we can have a number of ways to piggyback the best investors. We kept expanding the functionality, depending on what we were interested in for our own trading and research, and finally decided to open it up to everyone, with the idea that the more people involved in the sharing of ideas, the better the ideas will be. Here are some of the ways in which Stockpickr can help come up with good trading and investing ideas -- or if you can't wait, go over and check it out for yourself now -- you can either surf around and view others' portfolios, or you can get started on setting up your own. Recommendations: When you enter in your portfolio of stocks we look for portfolios that are related to yours. We look for Pro portfolios (the portfolios of the top hedge funds and mutual funds), top-rated portfolios, most-viewed portfolios, recently added portfolios, etc. Then, based on portfolios related to yours, and various other criteria, we come up with a blended set of 5 recommendations ranging from conservative to speculative.
