Dow futures rebounded more than 200 points on Tuesday, a day after the average of 30 stocks fell about three times during Wall Street’s fall in September. The Dow ended its worst price since July, down 614 points, or nearly 1.8%. The Dow lost 971 points from Monday’s low, nearly 5.7% below its intraday all-time high from the previous month. Investor concerns included risks during the Fed’s meeting this week, increased Covid cases in the US, debt caps in Washington and a possible financial market contagion from competitive Chinese developer Evergrande. The Nasdaq and S&P 500 had their worst days since May on Monday, falling 2.2% and 1.7%, respectively. Both were also more than 5% off their all-time intraday highs earlier this month.

The Fed has read the housing market as policy makers begin their two-day September meeting on Tuesday morning.

  • Housing starts in August rose better-than-expected 3.9% to an annualized rate of nearly 1.62 million units, compared to a revised decrease of 6.2% in July.
  • Building permits rose 6% to just under 1.73 million in August. Economists had seen a 2.1% drop. The July increase has been revised downwards slightly to 2.2%.

Central bankers will bring this data into the mix when considering when to scale back their massive Covid-era bond purchases. Hotter inflation, which Fed Chairman Jerome Powell sees as temporary, is being weighed against a recovering economy. However, a major disappointment in job growth in August could hold the Fed in check a little longer. Central bankers released their policy statement on Wednesday, followed by a Powell press conference.
