Editor's Note: The following are questions received from viewers of "Mad Money," seen every day at 6 p.m. EDT on CNBC.

How about answering your emails? You advertise the address on the show, but never write back. -- Bruce from Ohio

James J. Cramer:

Here you have it. I answer some of the hundreds of questions that come in every day on this page.

St. Joe (JOE) - Get St. Joe Company Report is down 8 points since reporting 66% earnings growth and raising its forward outlook. Are there more rocky days ahead?-- Christine from Rochester, N.Y.

James J. Cramer:

This is a stock I own for my charitable trust -- and in fact, I bought some earlier in the week. (To see all of the holdings in my charitable trust, visit


It is not surprising to see a company's shares pull back after a recent rally, even when it reports strong earnings. That said, I continue to believe the company's 800,000 acres of land in Florida are being undervalued by the market.

We are overweight in Apple Computer (AAPL) - Get Apple Inc. Report. Is this a good short-term strategy?-- Mark from Missouri

James J. Cramer:

James J. Cramer:

James J. Cramer:

While some folks argue that the electric, gas and water utilities are already too expensive, they do have many attractive characteristics for long-term investors. For one thing, utilities tend to offer above-average dividends. I'd also suggest sticking with the companies that operate in regulated markets, where selling prices and margins are more stable.
