J. Matthew Mackowski

J. Matthew Mackowski is a declared insider of Alpha Teknova, Inc., with filings sourced from SEC (Form 4). Between 24 August 2022 and 19 September 2023, the trades on record add up to 3 filings.

Purchases make up the whole of the open-market record (3 purchases, €1.5M). A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. In 2023 alone, the filings show 1 purchase and no sales.

The median purchase comes to €25k. 3 out of 3 purchases came within 30 days of a purchase by at least one other insider of the same company. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase. Looking at 3 purchases old enough to measure, the stock rose over the following 90 days in 100% of cases; the median change was +4.6%. They describe history only and say nothing certain about the share price ahead.

The newest entry dates from 21 September 2023: an open-market purchase of €1.4M, in Alpha Teknova, Inc. The median gap between a trade and its publication by SEC (Form 4) is 1 day. The legal deadline for a Form 4 is two business days after the transaction. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
