5 stocks to watch on Tuesday: LMT, DHI, KO, PM, and CSX

Stock index futures were little changed on Tuesday, with the S&P 500 coming off a new record high, as attention remained on earnings, as some big tech companies are set to report this week. Here are five stocks to keep an eye on for the day:

Lockheed Martin (LMT) fell 8% in premarket trade after the defense contractor reported sharply lower second-quarter earnings because of more than $1.6 billion in program-related charges, falling short of Wall Street expectations.

D.R. Horton (DHI) shares were up 6.3% before the opening bell after the company boosted its stock repurchase outlook and posted stronger-than-expected Q3 earnings and revenue. The U.S. largest homebuilder now sees fiscal 2025 revenue of $33.7B-$34.2B (midpoint $34.0B vs. $33.9B consensus), as compared to its previous outlook of $33.3B-$34.8B.

Coca-Cola (KO) stock fell 1% in premarket trade, erasing its earlier gain as it beat its organic sales estimates with its Q2 earnings report and backed its full-year guidance. Revenue was up 0.8% year-over-year to $12.5 billion for the quarter, and comparable EPS was up 4% year-over-year to $0.87.

Philip Morris (PM) was down 4.8% before the opening bell as the tobacco giant issued a mixed Q2 earnings report. The firm beat its bottom line estimates but missed the revenue consensus.

CSX (CSX) was up 3.8% in premarket trade as BNSF Railway has hired Goldman Sachs to explore a potential railroad takeover, and CSX (CSX) is in talks to bring on financial advisors, as Union Pacific’s (UNP) interest in acquiring Norfolk Southern (NSC) has sparked a wave of deal preparations in the U.S. freight rail industry. It is not yet clear whether BNSF (BRK.A) (BRK.B) would target Norfolk Southern (NSC) or CSX (CSX), the other east coast carrier.
