Ross Stores Grew Comparable Sales 10%. TJX Grew 4%. Only One Stock Went Up.

Ross Stores (ROST) surged 4% after reporting 10% comparable sales growth for its most recent 13-week period, driven by higher customer traffic. The discount retailer projected 6-7% comparable sales growth for Q3, signaling sustained momentum.

TJX (TJX) fell 4% despite posting 4% comparable sales growth and raising full-year guidance. The market punished TJX's conservative Q3 outlook: the company expects just 2-3% comparable sales growth next quarter, with its flagship Marmaxx division projected nearly flat.

The divergence highlights how forward guidance trumps backward-looking results in current market conditions. Ross's double-digit growth and optimistic outlook contrasted sharply with TJX's deceleration signal, even though TJX raised its full-year forecast. Both retailers reported results for identical 13-week periods, making the guidance gap the clear differentiator.

Ross's traffic-driven growth suggests stronger competitive positioning in the off-price segment, while TJX's Marmaxx slowdown raises questions about market share dynamics heading into the critical back-to-school and holiday periods.
