David Sponsel

David Sponsel (senior executive) discloses dealings in Alphatec Holdings, Inc. to SEC (Form 4). Between 13 May 2019 and 11 March 2026, the trades on record add up to 63 filings.

Both buying and selling appear: 1 purchase worth €44k, against 30 sales worth €12.2M. Taken together, the sales exceed the purchases by €12.1M. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. The rest of the record consists of 30 share grants and 2 option exercises. 2026 to date brings no purchases and 2 sales.

On 13 March 2026 came the latest disclosure, an open-market sale for €1.8M in Alphatec Holdings, Inc. The latest purchase dates back some time: it was published 2,416 days ago, on 12 March 2020. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. The legal deadline for a Form 4 is two business days after the transaction. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
