Citigroup gets an upgrade ... seriously?

Research firm Punk, Ziegel & Co is putting a "buy" rating on Citigroup (NYSE: C). The research firm feels that the bank is the best proxy for investing in the global investment industry and that its write-downs are secondary. Quoted by MarketWatch, the firm said "The stock allows one to invest in the world's financial growth better than any other company. Others perform in one part of the financial sector or operate in one portion of the world."

That comment may be akin to saying that if you are going to drown in quicksand, you might as well find the best quicksand available. Citigroup is hardly a strong investment and the fact that its business operations are global and that it operates in many sectors has nothing to do with whether the bank can do well over the next year.

Citigroup is being scuttled by huge write-offs in its mortgage-related investment portfolio. Earnings from other divisions in the company are not likely to offset this and the bank may have to raise more capital. The resulting dilution could certainly drive the price of the company's stock down. There have also been comments from Wall Street that the big bank may have to cut its dividend. That is likely to make it much less attractive to a certain category of "yield-minded" investor.

Citi shares could be hit by more write-offs and the need to bring in a large sum of new capital.

That hardly makes it a "buy."
