A gain of nearly 15% in one regular trading session is an exceptional move for a company of SanDisk's scale, and buyers held the bulk of those gains into the close.

The stock traded in a tight range just above the open through the morning, then accelerated sharply later in the session to its intraday high.

Holding above the $1,343 open price is the level to watch: continued support there would reinforce that buyers are willing to defend the new range.

Investors who were underweight or on the sidelines now face a sharply different entry point than they did at the open, the kind of session that forces a reassessment of positioning.
