Alphatec Holdings Inc. stock surged 18.50% to $10.48 on Friday as the CEO made a significant purchase of company shares and analysts raised price targets. The stock opened with a 6.1% gap up and continued to climb throughout the session, reaching a high of $10.54. Recent analyst activity and insider buying have drawn attention to the stock despite its 58% year-to-date decline.

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. The purchase occurred amid a broader market environment where several stocks were rising, including Alphatec. Analysts at UBS, TD Cowen, and BMO Capital have each raised their price targets for the stock, with UBS setting a target of $16, TD Cowen at $13, and BMO Capital at $12. These developments, combined with the CEO’s confidence in the company’s prospects, have driven the sharp increase in ATEC’s share price.

What The Data Shows

The stock’s intraday performance showed a strong upward trajectory, with volume reaching 3.3 million shares, or 1.1 times the 3-month average. The session low of $9.34 was quickly surpassed as the stock climbed to its high. On the 52-week tape, ATEC printed one fresh 52-week low and 33 fresh 52-week highs on the same day. The stock currently trades within its 52-week range of $6.82 to $23.29.
