Company News for Oct 2, 2026

Accenture (ACN) led the earnings tape, surging 15.8% after the company beat earnings estimates. It was the standout mover in a session that split sharply between winners and losers.

McKesson (MCK) gained 5.3% after maintaining its guidance. The move shows the market rewarded stability, with no raised outlook needed to drive the stock higher.

The downside came from two names. Acuity (AYI) fell 3.4%, while Progress Software (PRGS) dropped 8.5% after missing revenue expectations. PRGS took the steeper hit of the two, a sign that a top-line miss drew a heavier penalty than the other decliner.

Interpretation: the spread between ACN's 15.8% jump and PRGS's 8.5% drop, a gap of roughly 24 percentage points, suggests the market is punishing misses and rewarding beats with little middle ground. MCK's 5.3% gain on unchanged guidance reads as a reward for predictability rather than for acceleration. This is our read of the price action, not a stated cause from the reports.
