The Dow Jones Industrial Average is set to mark is third weekly decline of 1,000 points since February. On Friday, the Dow DJIA, -2.90% was off 277 points, or 1.1%, at 24,339, falling below its 100-day moving average at 24,447.63, according to FactSet. At its current pace, the Dow is set to shed about 1,000 points or more for the week, after recording back-to-back 1,000-point drops from Feb.9 to Feb. 16. The blue-chip gauge had been mounting a modest recovery since the main benchmarks, the S&P 500 index SPX, -2.20% and the Nasdaq Composite Index COMP, -1.32% fell into correction territory on Feb. 8, typically defined as a drop of 10% from a recent peak. However, worries about trade wars sparked by President Donald Trump's threat on Thursday to impose tariffs on steel and aluminum imports, fear of rising inflation and bond yields competing for investor attention against equities, and uncertainty about the Federal Reserve's path under newly minted chief Jerome Powell has made for a bearish cocktail for Wall Street stocks.
