Jim, is Yahoo! (YHOO) a good buy here?

-- William from New Hampshire

James J. Cramer: Yes, I believe Yahoo! is a buy; in fact, I bought some earlier for my charitable trust, ActionAlertsPLUS . Yahoo! has fantastic Web properties that are taking a lot of advertising dollars from traditional media, and I believe the company will have a strong third quarter.

Where can I learn about trading options?

-- Patrick from California

James J. Cramer: First, I don't recommend options trading for most investors, especially beginners. But I do have two resources for investors who are interested learning more about them: First, take a look at our own TheStreet.com Options Alerts. Second, I like 888Options.com, which has a lot of great educational material for options traders at all levels.
