The Nasdaq recorded the smallest decline among the three major U.S. benchmarks, although it still ended the session in negative territory.

The Russell 2000 also weakened, falling 0.54% to 2,956.45 points. The decline indicates that U.S. small-cap stocks also finished lower alongside the broader market.
