NEW YORK (TheStreet) -- Lockheed Martin Corp. (LMT) was upgraded to "buy" from "hold" at Stifel Nicolaus.

The firm said it raised its rating on the global security and aerospace company as it believes Lockheed will continue to use its large dividend and buyback to return cash to its investors.

Stifel has a $220 price target on Lockheed stock.

Separately, TheStreet Ratings team rates LOCKHEED MARTIN CORP as a Buy with a ratings score of A+. TheStreet Ratings Team has this to say about their recommendation:

"We rate LOCKHEED MARTIN CORP (LMT) a BUY. This is based on the convergence of positive investment measures, which should help this stock outperform the majority of stocks that we rate. The company's strengths can be seen in multiple areas, such as its solid stock price performance, good cash flow from operations, growth in earnings per share, increase in net income and notable return on equity. We feel these strengths outweigh the fact that the company has had generally high debt management risk by most measures that we evaluated."
