It would be a brilliant way for Freeport McMoRan to become less dependent on its labor-hostile Grasberg Mine in Indonesia while adding some producing mines in areas of the world it isn't already involved in. Another possible combination of companies might involve ABB, currently trading near its 52-week low with a market cap of $37 billion, and believe it or not, Emerson Electric. Who would be the acquirer and who'd be the acquired is debatable. Once again, finding the next Cooper Industries before it is taken over means looking within specific industry niches. For example, Pentair ( PNR) which agreed to acquire Tyco Flow Control from Tyco International ( TYC) earlier this year may keep on expanding through acquisitions. On the other hand, it could end up being acquired by an international company wanting a stronger toehold in the U.S., a company like GDF Suez of Franceland or Siemens ( SI) of Germany. You get the idea. Let Eaton's devouring of Cooper Industries whet your appetite for finding some other good matches. Then see if that may help you to anticipate the next big acquisition and positive investment outcome that will seem like a surprise to everyone else but you.
