NEW YORK (TheStreet) -- It seems every other day another activist money manager is in the news. Whether it is Carl Icahn, Bill Ackman, Jeffrey Gundlach, Dan Loeb or others, someone is making waves on Wall Street.
Another prominent investor usually stays under the radar -- despite his numerous appearances on CNBC. That's Mario Gabelli, whose Gamco Investors manages some $47 billion in assets.
As Wall Street continues to see more and more mergers and acquisitions (M&A) activity -- especially larger deals -- Gabelli and his clients have quietly and significantly profited from several of these transactions.
The bidding war between Tyson Foods (TSN) and Pilgrim's Pride (PPC) for Hillshire Brands (HSH) is just the latest in a string of prominent deals. Just today, Tyson agreed to buy Hillshire for $63 per share in cash, valuing the company at $8.55 billion. For the past several years -- back when the company was known as Sara Lee Corporation -- Gabelli has pounded the table over Hillshire and how heavily the market had discounted its shares. It seems as though he was right yet again.
