Exchange-traded funds exposed to utilities outperformed on Friday as investors fled stocks and other risky assets. The Utilities Select Sector SPDR Fund /zigman2/quotes/206645117/composite XLU -0.90% was up 0.5%, one of the only ETFs tracking the 11 sectors of the S&P 500 to be above water.

Stocks /zigman2/quotes/210599714/realtime SPX -2.45% lost ground Friday after some analysts pointed out that an ambitious fiscal relief plan from President-Elect Joe Biden was likely to face an uphill battle in Congress, even as economic data continued to disappoint.
