Mad Money Mailbag: Cameco's One Way to Go Nuclear

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

How do I invest in nuclear energy?-- Steve from Wyoming

James J. Cramer:

It's hard to invest directly in the nuclear industry, but I think you can own

Cameco

(CCJ) - Get Report

, which sells uranium to the nuclear industry, if you want exposure. There are some other players, like

USEC

(USU)

, but I view Cameco as the "best of breed" in this space.

What is your take on Jones Soda (JSDA) ?-- Jay from Tulsa, Okla.

James J. Cramer:

Jones Soda has a deal with

Starbucks

and

Target

, but its high cost of growth is taking a toll on the bottom line. I like the long-term trends, but until I see this beverage play improve its operating execution, I would rather own

Pepsi

(PEP) - Get Report
