Those potential profits, however, are subject to a host of variables, including the economy, interest rates, bank capital requirements and asset returns. McDonald favors some of the stronger banks, including JPMorgan Chase and PNC. JPMorgan, which rose 20% to $38.94 last week, now is valued at around seven times normalized earnings of more than $5 a share.

Goldberg favors Bank of America, whose shares were up sharply despite needing to raise an industry-leading $33.9 billion. The stock trades for less than five times Goldberg's estimate of normalized earnings of $3.47 a share. Wall Street believes BofA can raise required capital without much dilution. The bank said it plans to sell 1.25 billion of common shares and convert some of its preferred stock to common -- and to sell some non-core assets, including the Columbia investment-management business. Bank of America's $33 billion of preferred stock offers a high-yielding play on the bank's revival. The Series J 7.25% preferred trades around $15 (60% of face value of $25) for a yield of 12%. A former Merrill Lynch preferred issue, now called Series 5, trades for just $9, a fraction of its face value of $25. It has a yield of 11%. The BofA preferred dividends now look more secure, and the common yields next to nothing.

Credit-card specialists American Express and Capital One (COF) were strong; AmEx (AXP) shares rose 17% in the five sessions to $28.40, and Capital One gained 81% to $31.34. Because the stress tests took a rosier-than-anticipated view of potential credit-card losses, AmEx and Capital One weren't deemed to be capital-deficient. Many on Wall Street had expected that Capital One would be forced to boost capital.

One of best plays for fans of beleaguered Citigroup is its $15 billion of preferred stock, which is due to be converted into common shares in an exchange offer to get under way soon. Citi's Series P preferred traded Friday around $22.50, enabling investors to buy Citi common at around $3 a share, considerably below Citi's close of $4.02. Each preferred share is likely to get 7.3 common shares. The opportunity exists because arbitrageurs can't close the currently wide spread between the preferred and common, with Citi shares virtually impossible to short. Citi's trust preferred, which is senior to the regular preferred, also could be appealing. Some probably will be converted to common to meet the need for $5.5 billion of additional capital called for in the government stress tests. Citi's Series W trust preferred trades around 15, for a yield of 10%. Citi's common is a dicier bet because the company's plan to convert more than $50 billion of preferred stock to common to boost key capital ratios could balloon its share count to 23 billion from the current five billion, permanently capping its earnings power. Moreover, the government likely will emerge as a major shareholder, leading to further potential meddling in Citi's business. With Citi's business mix shifting, it's tough to peg normalized earnings power, which could be anywhere from 50 cents to $1 a share.
