The Dow Jones Industrial Average fell for a ninth straight day on Tuesday, its longest losing streak since 1978.

The U.S.’ bluechip stock index is mired in its longest stretch in the red since 1978, a potentially concerning signal for investors enjoying an otherwise sanguine period for stocks, though Tuesday’s losses are largely tied to a singular company—UnitedHealth Group—and gains remain healthy over a longer timeframe.

The Dow lost more than 250 points ahead of the Fed's decision on interest rates. Nvidia stock continued its correction, while Tesla shares jumped.
