U.S. stocks finish mostly lower as bank shares slide

U.S. stocks finished mostly lower on Tuesday, with only the tech-heavy Nasdaq Composite clinging to gains, as poor retailer earnings, rising Treasury yields and a slew of bank downgrades weighed on stocks. The S&P 500
SPX,
-0.28%
fell by 12.13 points, or 0.3%, to 4,387.63, according to preliminary closing data from FactSet. The Nasdaq Composite
COMP,
+0.06%
gained 8.28 points, or 0.1%, to 13,505.87. The Dow Jones Industrial Average
DJIA,
-0.51%
fell by 174.72 points, or 0.5%, to 34,288.97. A gauge of bank stocks also finished lower as S&P Global downgraded several midsize U.S. banks. Meanwhile, investors were looking ahead to earnings from Nvidia Corp., due out after the bell on Wednesday, and a speech later this week from Federal Reserve Chairman Jerome Powell.
