Palo Alto Networks climbed steadily through regular trading to $383.80, a gain of just over 7% on the day. The sustained upward drift points to genuine buying conviction.
A 7% single-session move for a company already valued at $314 billion is unusual by any measure. Mega caps that size rarely swing this sharply without forcing institutional investors to decide: chase the move or wait for a pullback.

Buyers stayed active into the final portion of the session, pushing the stock toward the $385 area rather than fading early gains. That late-day strength is the detail worth watching.
Holding these levels into the next session matters, because a gain of this size that sticks adds roughly $20 billion in market value. Analysts and portfolio managers will need to reset their baseline.
