U.S. stock indices extended yesterday’s losses, with the Dow on track to end the week in the red. The Dow Jones Industrial Average retreated 52 points, or 0.24% to 21,697.83 and the S&P 500 fell four points, or 0.14% to 2425.98. The Nasdaq Composite declined 5.8 points, or 0.09% to 6216.39.
In the grand scheme of things, Thursday's "plunge" in the Dow was quite pedestrian.
