BY THE NUMBERS

Dow futures rebounded more than 200 points Tuesday, one day after the 30-stock average slumped roughly triple that amidst Wall Street's September slide. Investor concern Monday included risks over this week's Federal Reserve meeting, elevated Covid cases in the U.S., debt ceiling brinkmanship in Washington, and possible financial market contagion from embattled Chinese developer Evergrande.

The Dow was down 971 points at Monday's low, which had been almost 5.7% below last month's intraday all-time high.

The Fed got a read on the real estate market as monetary policymakers are beginning their two-day September meeting Tuesday morning. August housing starts increased a better-than-expected 3.9% to an annual rate of nearly 1.62 million units compared to a revised 6.2% decline in July. Building permits in August rose 6% to nearly 1.73 million. Economists had seen a 2.1% drop. The July increase was revised slightly lower to 2.2%.

Central bankers will put that data into the mix as they consider when to start tapering their massive Covid-era bond purchases. Hotter inflation, which Fed Chairman Jerome Powell sees as temporary, will be weighed against a recovering economy. However, a big disappointment in August job growth could keep the Fed at bay a little longer. Central bankers release their policy statement Wednesday, followed by a Powell news conference. (CNBC)
