It was a solid day for stocks today, as the Dow (^DJI 0.04%) and the broader S&P 500 Index (^GSPC 0.06%) both advanced 0.6%. The S&P 500 achieved a new five-year high, but financials didn't play along -- they were the only losing sector today. In fact, JPMorgan and Bank of America (BAC 0.54%) were two of the three worst-performing stocks in the S&P 500, declining 0.8% and 4.2%, respectively. (Unsurprisingly, then, they were the worst performing Dow components.)
Why banks didn't play ball
Both B of A and Citigroup (C -0.99%) reported earnings today. The results were not well received; as mentioned above, B of A shares fell 4.2%; meanwhile, Citi shares lost 2.9%. As one New York money manager told Bloomberg:
Both organizations are, for lack of a better word, somewhat lost. [They] have been spending a significant amount of time dealing with the problems of the past rather than aggressively marketing the organizations.
I suspect this view is relatively popular among professional investors, who find it convenient to conflate the two companies' positions, performance, and prospects. (How's that for alliteration?) A reductive model of the universal banks has J.P. Morgan in a league of its own, completely separate from the second tier made up of B of A and Citi, which are still floundering.
Of course, the notion that this view is widely held is merely a hypothesis, and one that is difficult, at that. But if it is true, I think that part of the decline in B of A's stock is attributable to that of Citi's. You might retort: Why, then, would the former fall harder than the latter? Good question, but I think the recent relative performance of the two shares may help to answer it: 
Data by YCharts.
As the graph clearly shows, B of A shares have dusted Citi's over the three-month period ended yesterday, while both have smashed the broad market. In other words, on the heels of a strong run-up in their stock prices, B of A had further to fall than Citi.
You may have guessed that I don't share the view that B of A and Citi are similar organizations. Keep in mind, variant perception is a potential source of opportunity -- assuming it is correct.
