If you are new to investing and would like to learn about the stock market, financial planning, and more, please visit the Investment References and Guides category in the Yahoo! directory. There you can find a number of resources that assist you in getting started with stocks, bonds, mutual funds, and other investment vehicles.

With regard to actual trading, Yahoo! Finance does not provide any brokerage services. If you are interested in buying and selling stock, you need to open a brokerage account with a stock brokerage firm.
