Lockheed Martin (LMT: sentiment, chart, options) is one of the few companies making news on this slow trading day. The defense firm said this morning that it has entered into a definitive agreement to acquire Universal Systems & Technology, Inc. (UNITECH). The firm provides interactive training simulations and other technical solutions to the U.S. military and other government agencies. Financial terms of the deal were not disclosed.

"This transaction is another step forward in our long-term strategy of building shareholder value by using disciplined cash deployment to make acquisitions that strengthen our core competencies," said Bob Stevens, LMT's chairman, president, and CEO.

The transaction is expected to close in early 2009, pending regulatory approval. In early trading, LMT is up 0.5% at $78.69.
