Updated from 11:13 a.m. ET with market close information and comment from JPMorgan Chase analyst Vivek Juneja. NEW YORK ( TheStreet) -- "Past performance does not guarantee future results." How many times have you read or heard this irritating but accurate disclaimer? It's true, of course, but when it comes to considering long-term investments in bank stocks, looking at past performance can be very useful. After all, the industry is still emerging from the earth-shattering crisis of 2008. Earnings season for the nation's largest banks begins on Friday, with JPMorgan Chase ( JPM) and Wells Fargo ( WFC) scheduled to announce their first-quarter results before the market opens. Citigroup ( C) will report on April 15, and then Bank of America ( BAC) will round out the "big four" U.S. bank holding companies with its first-quarter earnings announcement on April 17. So over the next two weeks, we will see breathless headlines saying whether or not the big banks have beaten quarterly earnings estimates. Then the sell-side analysts will make adjustments to their 2013 and 2014 earnings estimate and price targets. Most of the price targets have 12-month outlooks, with some analysts going out to 18 months. The headlines are geared toward day-traders, and even the "long-term" price targets of the analysts are not for periods that have traditionally been considered long-term for the average investor. Being a day-trader is wonderful, especially if you are a successful one. But for the average investor, a solid, truly long-term investment in a company with a consistently high return on equity can only bear fruit over a period of many years. When we look at the big banks, while acknowledging that past performance cannot guarantee future results, the "past" for this industry has been pretty lousy, and good performance during the doldrums of the credit crisis can at least point to a comforting tradition for solid management. According to data supplied by Thomson Reuters Bank Insight, Wells Fargo's return on average tangible common equity over the past five years has ranged from 7.15% to 16.95%. JPMorgan was the only other member of the big four club that also managed to achieve positive returns on tangible equity during that period, ranging from 6.55% to 14.92%. Even if we leave out the "bad year" of 2008, a comparison of returns over the past four years for the big four, is striking:
