New York and Philadelphia have some of the most hardcore fans in Major League Baseball. These fans don't just get excited about a game as big as the World Series, they get stressed out.

And stress isn't good for anyone's health, and neither are the hot dogs New York fans will gorge themselves on, or the cheese steaks the Philadelphia fans will wolf down. Plus, fans in both cities are going to be washing that heart-attack-waiting-to-happen chow down with too much beer. No doubt many of them will be suffering from sleep apnea.

Baseball fans worldwide continue to warm themselves around the glow of the television to watch the Phillies and Yankees battle it out in the World Series.

Well, sports fans, I know you're psyched, but I have something just as exciting for you: six home run trades.

Peter Lynch had his "take a walk down Main Street" style of investing, so let's call this the "take me out to the ball game" approach to trading. I'm going to give you six trades that I think will knock it out of the park.

TheStreet.com's Jim Cramer says the exchange rate plus massive undervaluations make the great brands prime targets.

There's always been a groupthink in Europe about currencies. The companies that want to buy American companies have, at times, seemed to care more about the currency, or at least not buying a company in a country whose currency is in decline, than they care about the actual target.

That's what it looks like now that a large German company and now a large Italian company have decided to start splurging. It is no coincidence that Deutsche Tel (NYSE: DT) (Cramer's Take) and Finmeccanica are exploring Sprint (NYSE: S) (Cramer's Take) and DRS (NYSE: DRS) (Cramer's Take). These companies are selling for something like 40% off for those bearing euros, and neither potential acquirer has debt problems or subprime issues, so the deals don't have big borrowing problems.

That's what I am thinking about when I see the better-than-expected figures today from Unilever (NYSE: UL) (Cramer's Take) and the other day from Nestle. These companies are part of that same groupthink. They are looking, no doubt, at a Heinz (NYSE: HNZ) (Cramer's Take) and thinking, "Wait, that's about a $10 billion company that's a global leader."

MOST NOTEWORTHY: Intel Corp (INTC), Advanced Micro Devices, Inc (AMD), Post Properties, Inc (PPS), Analogic Corp (ALOG) and the base metals sector were today's more noteworthy upgrades:
