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

What do you think of IdaCorp (IDA) - Get Report?-- Gary from Oregon

James J. Cramer:

I like what I see at this electric utility. The company has cleaned up its balance sheet and pays a 4% dividend yield. The company also has investments in several alternative energy projects.

I bought Nokia (NOK) - Get Report around $15, and now the shares are approaching $20. What should I do?-- Brendan from California

James J. Cramer:

Remember, it doesn't matter where a stock has come from. What matters is where it's going. After being battered by

Motorola

( MOT) in mobile handsets over the past several quarters, I believe Nokia is back and better than ever. With that in mind, the shares could keep moving into the low-$20s during the first half of the year. (Note: Cramer owns shares of Motorola for his

ActionAlertsPLUS charitable trust.)
