HCA Healthcare is Wednesday's IBD Stock of The Day as the nation's largest hospital operator outperforms the S&P 500, in part because it isn't just immune from AI disruption but becoming more resilient thanks to technology and other help from Palantir Technologies. HCA stock is in a buy zone as it works on a four-session winning streak. Despite the expiration of enhanced subsidies for Affordable Care Act health coverage purchasers, who accounted for 10% of HCA's revenue last year, "margins are expected above 20%, in line with '25," wrote Jefferies analyst Brian Tanquilut in a Jan. 27 note.
