Cummins Drops Nearly 5%, Shedding About $3 Billion in One Session
As seen on the 24/7 Wall St. homepage on November 4, 2026.

Cummins slid through the session to settle near $474.53, a drop of roughly 4.9% from the open in a stock that typically trades with far less volatility.
The stock fell sharply at the open, briefly found footing in the mid-$480s, then resumed its decline before stabilizing just above $474. A failed early bounce followed by continued pressure tends to reflect sustained selling rather than a single reactive flush.

For a name the size of Cummins, a nearly 5% single-session drawdown is uncommon. The engine and power technology company carries a market capitalization in the tens of billions, and moves of this magnitude in one day tend to draw attention from institutional investors reassessing their position sizing.
Whether the stock holds the levels reached late in the session matters into the close and the following morning. A failure to stabilize above the intraday lows would suggest sellers remain in control, while a recovery toward the $480s would signal the initial reaction was overdone.
