Teradyne insider sale separates trade and filing dates
The SEC’s October 19 Form 4 filing record identifies Marilyn Matz as the reporting person and Teradyne as the issuer, with an October 15, 2026 reporting period. The filing date marks the disclosure’s submission, rather than the date of the share sale.
The filing-detail page confirms those identities and dates but does not display the transaction table containing the share quantity and remaining holding. Adding the reported sale to her post-transaction position gives an implied pre-sale holding of 13,840.675 shares.
The transaction concerns a director’s personal ownership, not newly issued shares sold by Teradyne to raise capital. It therefore does not represent revenue or financing proceeds for the company.
| Item | Details |
|---|---|
| Matz shares sold over the preceding year | 6,800 shares |
| Matz shares purchased over the preceding year | 0 shares |
| Companywide insider sale transactions over the preceding year | 32 |
| Companywide insider purchase transactions over the preceding year | 0 |
Annual trading history shows sales, not motives
The trailing-year transaction history shows sales by Matz and other Teradyne insiders without recorded purchases. These counts describe trading activity, but they do not establish why individual insiders sold or demonstrate a shared view of the company’s prospects.
The available details do not establish whether Matz’s transaction reflected diversification, liquidity needs or a prearranged trading plan. Nor does the absence of purchases, by itself, provide a forecast for Teradyne shares.
Teradyne designs and manufactures automated test equipment and robotics products. Its semiconductor test systems serve chipmakers and outsourced assembly and test providers, while its robotics products are used in manufacturing, logistics and other industrial settings.
Conclusion
Matz’s sale reduced but did not eliminate her Teradyne stake. Subsequent ownership disclosures would be needed to determine whether her selling continues; this transaction alone does not establish her outlook for the company.
