WASHINGTON—Profit margins of S&P 500 companies have soared to their highest level in a decade, as businesses start to see the effects of U.S. tax reform.
The blended net profit margin of companies in the index rose to 11.8 percent in the second quarter, the highest level since financial data provider FactSet began tracking the measure in 2008. It’s also the third consecutive quarter for double-digit earnings growth across the index, according to FactSet.
