Jim Cramer recommended Molson Coors (TAP - Get Report) but didn't like the outlook for ManTech (MANT - Get Report) on his "Mad Money" show Thursday night. Both companies traded higher Friday.

On Friday, shares of Molson Coors closed higher, up $0.46, or 1.46% to $34.10. Shares of ManTech closed higher too, up $0.02, or 0.05% to $43.98.

Cramer interviewed Peter Swinburn, president and CEO of brewer Molson Coors, to find out how the beer company is managing the difficult economic climate. Swinburn characterized the company's business as "surprisingly resilient."

Calling Molson Coors one of the few Obama-resistant companies left, Cramer recommended the stock.

Below, Dan Fitzpatrick ( RealMoney contributor) talks about Molson Coors in a video that appeared on TheStreet.com Friday morning.

Regarding ManTech's crash earlier this week, Cramer said you can spot trouble with a stock before it happens.

Up until January, he said, ManTech had performed strongly in a down market. But then during the week ending Jan. 30, the stock tried to stage a technical breakout, only to fail and retreat to the bottom of its weekly range. Cramer said this signals that big institutions were looking to sell rather than hold.

In the following weeks, shares of ManTech rallied back, but on light volume, only to get hit with another round of selling. This time, however, the stock plunged below its key 10-week and 40-week moving averages, clearly showing that the big guns were getting out.

Cramer said the fundamentals at ManTech were also signaling trouble and the company has a two-tier stock structure, which is another red flag that he avoids at all costs.

At the time of publication, Cramer had no positions in the stocks mentioned.
