Earnings season begins tomorrow for U.S. banks, and the consensus opinion is that the top banks' performance will do nothing to lift the pall that hangs over them. However, as we look beyond the second quarter (and beyond 2011), there is reason to believe the sun will shine on bank share investors.

The hits keep on coming
The latest concern to hit the top banks relates to declining trading revenue. With the exception of Wells Fargo (NYSE: WFC), this affects the entire top tier of the industry. But investment banks, which aren't as diversified as the universal banks, will be hardest hit. Just look at the way analysts penalized Goldman (NYSE: GS) and Morgan Stanley (NYSE: MS) last week, taking a hatchet to their earnings estimates for the second quarter:

With regard to full-year earnings, this group has suffered continual downgrades over the past month (again with the exception of Wells Fargo). As a result, my basket trade idea, which was outperforming the market during the first quarter, is now in the red, lagging the market by a substantial margin. While there remains uncertainty regarding financial reform and the costs due to soured mortgage securitizations, I think the market may be underestimating the significance of one key matter that was largely settled last month.

An opportunity for patient capital
Minimum capital requirements affect banks' long-term earnings power, and while there will be no returning to the "performance-enhanced" profitability of the credit bubble, the new, stricter requirements still leave room for banks to earn returns in excess of their cost of capital. Despite that, the group trades at a modest premium to tangible net asset value (a measure of the bank's accounting net worth, which excludes intangible assets including goodwill), suggesting the group represents an opportunity for patient capital.
