As I predicted yesterday, Cyprus managed to hammer out an agreement with its international lenders, thus averting a banking collapse (although its offshore-banking franchise has been irreparably harmed). This morning's opening suggests instead that investors are cheering the result, with the S&P 500 (SNPINDEX:^GSPC) and the narrower, price-weighted Dow Jones Industrial Average (DJINDICES:^DJI) up 0.5% and 0.32%, respectively, at 10 a.m. EST. The S&P 500's record (nominal) high of 1,565.15 of Oct. 2007 could well fall today.

These banks can still run
Shares of Dow component Bank of America (NYSE:BAC) and its peer Citigroup (NYSE:C) have easily bested the market over the past 12 months:

Can this outperformance continue? There is at least one good reason to think so: The shares have an underweighting in some of the largest actively managed U.S. mutual funds:



Bank of America


American Funds Growth Fund of America (Dec. 31, 2012)

$114.8 billion



American Funds Income Fund of America (Dec. 31, 2012)

$72.9 billion



American Funds Capital Income Builder (Dec. 31, 2012)

$78.3 billion



Fidelity Contrafund (Jan. 31, 2012)

$61.5 billion



Franklin Income Fund (Dec. 31, 2012)

$73.4 billion



American Funds Investment Company of America (Dec. 31, 2012)

$57.2 billion

These funds were no doubt burned by the meltdown in bank shares during the financial crisis, and they are tremendously conservative organizations. Both of these factors create inertia in the decision-making process, and as such, these funds' holdings can be thought of as lagging indicators of performance. Once their holdings in B of A and Citi reflect (or exceed) the allocations dictated by their benchmarks, the shares will have run. The funds themselves, because of their massive footprints, will have played a big role in sparking that outperformance. Investors who stay one step ahead of them can reap the returns.
