Large-cap stocks like Tractor Supply and Lululemon fell sharply last week amid earnings misses and cautious forecasts.

Last week, major large-cap stocks including Tractor Supply, Lululemon, Northrop Grumman, and Lockheed Martin experienced significant declines due to disappointing earnings reports, cautious future outlooks, and analyst downgrades. For example, Tractor Supply dropped 18.54% after missing Q1 expectations and lowering its FY26 EPS guidance midpoint. Lululemon fell 13.56% following a CEO change, while defense companies Northrop Grumman and Lockheed Martin saw declines after earnings misses and lowered forecasts. These drops reflect sector-specific challenges despite a mixed overall market environment, signaling investor caution ahead.
