GoPro is the clear standout at the open, with shares climbing 10.3% to $1.16.

Moderna is close behind as the most consequential gainer by dollar terms, with SanDisk, Datadog and Applied Digital keeping the top five tightly clustered on the upside.

The losing side of the ledger is contained, with HDFC Bank the steepest decliner and the rest of the selling pressure well within a normal day's noise.

The biggest gain at this open is more than three times the size of the biggest loss, so the tone of the session skews meaningfully toward buyers.
