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:

• DA Davidson raised Intel Corp's (NASDAQ: INTC) rating to Buy from Neutral based on market share gains and unexpected PC growth.

The firm suspects AMD could win a notebook platform at Toshiba Corp (TOSBF) and expects further offerings at Dell Inc (DELL).

• Banc of America upgraded shares of Post Properties Inc (NYSE: PPS) to Neutral from Sell and raised their target to $53 from $42 after REIT Wrap, a real estate industry newsletter, reported the company may have already received several unsolicited bids.
