Major U.S. equities indexes ticked higher to start the new trading week after the Trump administration announced smartphones, computers, and other electronics would be exempt from “reciprocal” tariffs, even as Commerce Secretary Howard Lutnick suggested that the carve-outs could be only temporary.
The S&P 500 and the Dow ended Monday’s session approximately 0.8% higher, while the Nasdaq gained 0.6%.
Charles River Laboratories (CRL) posted the strongest daily gain of any S&P 500 stock, as shares added 6.9%. With Monday’s push higher, the stock clawed back a portion of the sharp decline posted late last week after the Food and Drug Administration said it would phase out animal testing requirements in the development of monoclonal antibodies and other treatments.
Palantir Technologies (PLTR) shares surged 4.6% after the North Atlantic Treaty Organization (NATO) announced it acquired an AI-based military system developed by the data analytics software firm. NATO said the procurement, “was one of the most expeditious in NATO’s history, taking only six months from outlining the requirement to acquiring the system.”
Several stocks in the health care sector lost ground as health insurers gave back some of the gains posted last week after the government said payments to Medicare insurers next year would be higher than previously expected. Humana (HUM) shares, which have been under pressure over the past year amid downgrades to its Medicare offerings and soft membership additions, sank 3.5%, marking the weakest performance in the S&P 500. UnitedHealth Group (UNH) shares fell 2.1% ahead of its earnings report expected later this week.
DaVita (DVA), which provides dialysis services for patients with kidney disease, announced it had been affected by a ransomware attack. According to a filing with the Securities and Exchange Commission, the incident resulted in the encryption of certain elements in DaVita’s network and affected parts of its operations, but the health care company said it is taking measures to mitigate the issues. DaVita shares dropped 3% Monday.
Southwest Airlines (LUV) shares declined 2.4% after the carrier said its travel credits would expire 12 months from the purchase date of the original ticket for most flights, ending its policy of providing credits with no expiration date. The new policy marks the end of another longstanding perk for the airline, which moved toward a paid baggage model last month, raising concerns that more Southwest travelers could be required to gate-check their carry-on luggage.
