Dow, S&P 500 drop as U.S. bank rally wanes, tech boosts Nasdaq

The S&P 500 closed lower and the Dow ended a seven-day rally on Wednesday as financial stocks fell but gains in technology stocks helped Nasdaq end the day higher. The Dow had closed higher for the previous seven sessions, with the last four at record levels. Both the Dow and S&P pared losses in choppy afternoon trading.
