U.S. stocks fell broadly on Friday, with all 30 Dow components in negative territory as trade tensions between the U.S. and China resurfaced and investors grappled with a weak reading on the labor market. Two industrial stocks seen as having a high correlation to trade issues, particularly with respect to China, were among the biggest declines: both Boeing Co. BA, -2.37% and Caterpillar Inc. CAT, -3.02% fell 1.7%. Among other stocks pressuring the blue-chip average, Goldman Sachs Group Inc. GS, -1.80% fell 1.5% and J.P. Morgan Chase & Co. JPM, -1.67% was down 1%. On the other end of the spectrum, Coca-Cola Co. KO, -0.56% and Procter & Gamble Co. PG, -0.23% both inched into positive territory in early trading before subsequently retreating back into the red. The Dow DJIA, -1.49% fell 0.8% while the S&P 500 SPX, -1.12% was down 0.7% and the Nasdaq Composite Index COMP, -0.91% was down 0.7%.
