Key questions

• How significant was this sale relative to the insider’s typical transaction size?
  The 32,584 shares sold are materially below both the recent median sale of 60,876 shares and the historical median of 59,119 shares for Hunsaker's sell-only events, indicating a smaller-than-usual transaction.
• What portion of the insider's holdings did this trade represent?
  This sale accounted for 2.53% of Hunsaker’s direct ownership at the time, which is slightly below his historical median of 2.79% per sell trade and less than several large sales completed after February 2023.
• Was there any indirect or derivative activity involved?
  No; the disposition involved only directly held common stock, with no participation from trusts, entities, or options activity.
• Does the reduced size reflect a change in selling cadence or remaining capacity?
  The declining trade size is consistent with reduced remaining share capacity, as Hunsaker's direct holdings have fallen by more than half since January 2023, limiting the scale of further sales.

What this transaction means for investors

Company insiders may sell shares for any number of reasons, including liquidity or tax purposes, and while it can be wise to follow the moves of managers and institutional investors, observers should be cautious about the conclusions they draw.

That said, Hunsaker's sale appears to have been lucrative. Alphatec's 116% rise over the last year trounces the benchmark S&P 500's 15% total return and the 2.8% decline in the State Street SPDR Health Care Equipment ETF, which also holds Alphatec stock. Alphatec is a small-cap stock in the medical technologies space, which can present a lot of exciting upside, but also comes with big risks.

Despite a solid preliminary report in January 2026, the stock dropped nearly 22% in one day on a disappointing mid-teens growth projection. The company also remains unprofitable. But there may be more positive developments on the horizon. The company recently announced a partnership with Theradaptive that gives Alphatec exclusive U.S. rights to commercialize its spinal fusion technology, OsteoAdapt. OsteoAdapt is still in clinical trials, but if the partnership translates into surgeon adoption and revenue growth, it could benefit handsomely. Investors who believe in the industry's potential and Alphatec's ability to capitalize may want to consider an investment here. But regulatory risks remain, and Alphatec is focused on a very specific healthcare solution in a competitive environment, which adds risk to the investment thesis for those looking for a foundational investment.
