NEW YORK (Reuters) - Activist hedge fund MMI Investments LP, which had taken positions in several technology and defense companies and successfully pushed for deals in some cases, is winding down, people familiar with the matter said.
New York-based MMI, run by partners Clay Lifflander and Jerome Lande, has been liquidating its portfolio and has stepped away from all investments over the past several weeks, the sources said.
In 2010, MMI urged long-time takeover target Applied Signal Technology to solicit buyout offers, resulting in a $490 million sale to Raytheon Co
It was not immediately clear why the fund is liquidating, but one of the sources said it was a personal decision among people in the partnership group and was an amicable breakup.
Representatives for the fund were not immediately available for comment.
In one of its most recently disclosed investments, MMI took a 3.3 percent stake in communications equipment maker Comtech Telecommunications Corp
The activist fund had a mixed track record in its investments last year -- which typically involved taking a minority stake in companies and urging them to consider a sale.
Last summer, MMI amassed a near 10 percent stake in Kratos Defense & Security Solutions
MMI also failed to convince the board of Checkpoint Systems Inc
The aerospace and defense sector has seen increasing shareholder activism over the past years as stocks languish across the board amid worries about severe budget pressure.
