On Tuesday night's "Mad Money" show, Jim Cramer recommended buying Wells Fargo ( WFC), JPMorgan Chase ( JPM), Morgan Stanley ( MS), Goldman Sachs ( GS), Bank of America ( BAC) and Citigroup ( C) on any weakness until March 31. He owns the first four of those six stocks for his Action Alerts PLUS charitable trust.Cramer said that Treasury Secretary Geithner has instilled new confidence in the market and that hedge funds are once again interested in buying. Cramer said he anticipates a financial rally by the end of the month. On Wednesday, Wells Fargo closed up 92 cents, or 5.9%, at $16.42; JPMorgan closed up $2.16, or 8.2%, at $28.56; Morgan Stanley closed up 79 cents, or 3.1%, at $25.91; Goldman Sachs closed up $2.35, or 2.1%, at $112.95; Bank of America closed up 48 cents, or 6.7%, at $7.70; and Citigroup closed down 6 cents, or 2%, at $2.95. Cramer's dividend-stock recommendation for Tuesday night was Procter & Gamble ( PG), which has raised its dividend every year for the past 52 years, including last year, when the dividend gained 14%. Cramer was confident that the dividend would go up again this year. The stock is widely disliked, said Cramer, but he also likes the stock as a play on the weakening dollar, because 61% of the company's sales come from outside the U.S. He said the stock is also a play on lower commodity costs. Procter & Gamble closed up 99 cents, or 2.1%, at $48.06 on Wednesday. Cramer also liked 3M ( MMM), which he owns for Action Alerts PLUS, and Honeywell ( HON).
