Stock research

This is a good resource to research new stocks. Yahoo finance gives current news about the company from respectable sources like the Wall Street Journal, Fools, and Investment Business Daily (among others). The charts have a variety of settings including daily, three-month, six-month, year-to-date and max date ranges. You can compare stocks, show events (stock splits, dividend, etc.), and use a variety of technical indicators (simple moving average, volume, etc.).

Portfolio

The service allows you to create different stock portfolios. You can create one for your holdings and one for your watch list. The portfolio page gives a nice grid layout of your stocks with a variety of information like last trade amount, percent change, volume and details about your shares (number of shares, priced paid, gain/loss, etc.). The downside of this service is that the stock price has a 20 minute delay.

This is an excellent resource to use when you’re getting started investing. I have personally used the service for several years and would recommend it to anyone just starting out.
