03:49 PM EDT, 03/27/2025 (MT Newswires) -- US benchmark equity indexes are on track to close lower on Thursday, as markets weigh the impact of the new auto tariffs.

The Dow Jones Industrial Average dropped 0.2% to 42,387.6, while the Nasdaq Composite decreased 0.1% to 17,875.4. The S&P 500 was down 0.1% at 5,709.5. Consumer staples and consumer discretionary sectors had the biggest gains, and energy saw the steepest decline.

Dollar Tree ( DLTR ) was the top gainer on the S&P 500, with shares up over 10%. The discount retailer agreed to sell its Family Dollar business on Thursday to investment management firms Brigade Capital Management and Macellum Capital Management in a deal worth roughly $1.01 billion.

Abbott Laboratories ( ABT ) was up 4%. The company has received CE Mark certification in Europe for its Volt pulsed field ablation system to treat patients with heart rhythm disorders, such as atrial fibrillation.

General Motors ( GM ) shares were down 6.8%, the worst performer on the S&P 500. GM may be more exposed to a potential impact from new tariffs as its production in Mexico and Canada is more than double than that of Ford's (F), UBS Securities said in a note.

The 10-year US Treasury yield gained 1.5 basis points to 4.4%, while the two-year rate was down 2.7 basis points to 4%.
