Sr. Vice President · CADENCE DESIGN SYSTEMS INC (CDNS)
This is the public record of open-market stock transactions Chin-Chi Teng has reported to the SEC on Form 4 as Sr. Vice President of CADENCE DESIGN SYSTEMS INC (CDNS). Every figure below is the reported share count multiplied by the reported price, so the dollar amounts are exact disclosed values rather than estimates. It is a record of what has been filed, not a portfolio or a recommendation, and insider selling in particular is routine and rarely a signal on its own.
Most of Chin-Chi Teng's sales were pre-scheduled or tax-related rather than discretionary, which further weakens any read of them as a market call.
All 8 disclosed transactions, newest filing first.
How many shares has Chin-Chi Teng bought and sold?
Chin-Chi Teng has disclosed 8 Form 4 transactions in the record we track, from Aug 18, 2025 to Aug 21, 2026: 8 sales worth $15,268,151 and no open-market purchases. Each figure is the reported share count multiplied by the reported price, so these are exact disclosed amounts, not estimates.
Is Chin-Chi Teng selling a bearish signal?
Not on its own. Insiders sell for many reasons that have nothing to do with a view on the stock — diversification, taxes, estate planning, or a pre-scheduled plan set up months earlier. Of the 8 sales on this record, 8 were made under a Rule 10b5-1 plan and 0 were automatic tax withholding on vesting shares, leaving 0 that were the insider's own discretionary decision (worth $0). Buying is the cleaner signal, because there is only one reason to buy. This page is a record, not a recommendation.
What is Chin-Chi Teng's role?

How current is this record?
The most recent Form 4 here was filed Aug 25, 2026. Insiders have two business days to file after a trade, so this is close to real time, but it is a record of what has been disclosed, not a statement of what Chin-Chi Teng currently holds.
