Bristol Myers Squibb added roughly $5 billion in market value in a single session, a move that is unusual for a $120 billion drugmaker.

The buying was broad and persistent across the full session rather than a quick burst, a more constructive signal for investors.

A 4.1% single-day gain in large-cap pharma is rare enough to demand attention, and a move of this magnitude reflects something investors are repricing in a meaningful way.

Whether the gain holds into the close is the key question now, since a finish near the day's highs would reinforce the strength of the buying.
