NEW YORK, August 3, 2026, 11:17 EDT — Alerts regarding TSMC stakes reference March holdings, while the most recent filing signals a slowdown in share purchases.
- Each of the three alerts refers to positions as of March 31. The latest alert was issued on August 3.
- The managers boosted their holdings of TSMC depositary shares by 143,283 in the first quarter, marking a total rise of 30.0%.
- Positano’s latest June-quarter filing indicates an increase of just 170 shares, with its pace of additional purchases dropping by 88.6%.
Three institutional stake alerts for Taiwan Semiconductor Manufacturing Co Ltd NYSE:TSM record rises as of March 31. These are not new trading notifications.
TSMC’s U.S.-listed stock rose roughly 0.3% to $405.34 as of 11:02 EDT, with the U.S. cash market trading.
The difference is important. A late 13F notice may reflect confidence from previous months, but it does not verify a current stake.
An August 3 article on Positano referenced the March filing as the latest disclosure. However, SEC filings indicate Positano submitted a June 30 portfolio on July 20.
