What Happened

The CEO of Alphatec Holdings, Patrick Miles, purchased $1.01 million in company stock at $8.81 per share. This move came ahead of the stock’s strong premarket performance and continued rally during the session.

These developments, combined with the CEO’s confidence in the company’s prospects, have driven the sharp increase in ATEC’s share price.
