AI Insider Summary

A decade of routine, scheduled selling at Teradyne is all there is to Gregory Stephen Smith's Form 4 record — 162 transactions since 2017, 203,915 shares sold and none bought. What makes this record distinctive isn't the selling pattern itself — a scheduled, monthly sale program is common in this dataset — but the price trail those sales leave behind: monthly sales of 554 shares ran from $105.73 in July 2025 to $126.39 by September, then the scheduled sale size stepped up to 1,108 shares as the price kept climbing through $145.24 in October, $180.20 in November, and $201.31 in December 2025. By May 2026, a cashless option exercise (4,597 shares at a $72.10 strike) was matched with an 8,597-share sale at $338.98, and June 2026 brought a 4,000-share sale at $423.03 — before the most recent transaction, a 4,000-share sale on July 15, 2026, came in lower, at $356.31. Across roughly a year of routine, scheduled transactions, the recorded sale prices trace Teradyne stock climbing from the low $100s to over $400 and then pulling back.

A rising sale size tracking a rising price

From mid-2025 through the end of the year, a monthly sale of 554 shares recurs at increasing prices: $105.73 on July 30, $106.00 on August 12, $115.00 on September 12, and $126.39 on September 22. Starting in October 2025, the scheduled sale size roughly doubled to 1,108 shares per month, and the price kept climbing: $145.24 in October, $180.20 in November, and $201.31 in December 2025 — a nearly 90% increase in the stock price across those six months alone, visible entirely through the lens of a fixed, recurring sale.
