When's the worst time to raise money? Well, of course, when you desperately need it.

That's the predicament for Washington Mutual Inc. (NYSE: WM), which needs to shore up its beleaguered balance sheet. Rejecting a buyout offer from JPMorgan (NYSE: JPM) for $8 per share, WaMu has instead opted for a $7 billion capital infusion from an investor group that includes private equity maestros, TPG.

Unfortunately, the deal is extremely dilutive. In fact, a Goldman Sachs (NYSE: GS) analyst -- James Fotheringham -- thinks that investors should actually short the common stock of WaMu and buy the company's bonds.

It's a bold call -- but seems to make sense. The capital infusion should be a back-stop on the bonds. At the same time, there is likely to be more problems in WaMu's core business, as the economy continues its sluggish ways.

Simply put, Fotheringham thinks that WaMu shares should trade at its tangible equity value, which is estimated at $9.84 per share. Plus, he thinks there will need to be about $14 billion set aside for charges on bad loans. Oh, and profits aren't likely to come until 2010, which is an eternity for equity investors.

However, for individual investors, it can be quite risky to short stock. In other words, perhaps the best policy is to stay clear for awhile on WaMu.
