TSM VP Chuang Juiping Buys 50 ADS ($3,810)

What Happened

• Chuang Juiping, a Vice President at Taiwan Semiconductor Manufacturing Co. (TSM), made an open-market purchase (code P) of 50 American Depositary Shares (ADS) on 2026-09-07 at $76.20 per ADS, for a total cost of $3,810. This was a purchase (adds exposure) rather than a sale.

Key Details

• Transaction date: 2026-09-07; Filing date (Form 4): 2026-09-09 (filed two days after the trade; appears timely).
• Price: $76.20 per ADS; Total value: $3,810.
• ADS conversion: Each ADS represents 5 common shares (footnote F1) — 50 ADS = 250 common-share equivalents.
• Price translation: the $76.20 price was converted from NT$2,404.3453 using NT$31.552 = US$1 (footnote F3).
• Shares owned after transaction: not specified in the excerpt provided.
• Additional footnotes on the filing (F2, F4, F5) reference ESPP purchases/holdings and LTI-trust holdings; they describe other plan-related holdings but the reported line here is an open-market purchase.

Context

• Purchases by insiders are often watched by retail investors as one signal of confidence, but they are one data point among many; this single modest purchase ($3.8k) is relatively small. The ADS structure means the reported ADS count understates the underlying common shares (multiply ADS by 5 for common-share equivalents).
