Taiwan’s benchmark faded from an early push past 44,800 to close at 44,225.91 on Friday, down 0.38%, as foreign investors sold a net NT$40.72 billion in the cash market. TSMC edged higher against the tide; UMC fell 4.5%. Monthly revenue filings land Monday.
Taiwan’s benchmark jumped 1,250.94 points on Wednesday as a record-setting Wall Street session and a 6.5% surge in the Philadelphia Semiconductor Index lit up the AI hardware complex. Foreign investors bought NT$90.31 billion of cash equities — the day’s defining number.
Taiwan’s TAIEX closed up 0.62% at 43,386.41 on Monday despite a 2.27% drop in TSMC, as MediaTek’s near-limit-up surge and rotation into memory and passive components carried the tape. Foreign investors sold NT$19.19B; investment trusts bought NT$21.07B.
Taiwan’s benchmark fell 4.65% to 41,603 on Tuesday as foreign investors dumped a net NT$87.56 billion. MediaTek and UMC fell close to 10%, TSMC lost 2.98%, and the sell-off tracked a region-wide unwind of AI infrastructure trades.
Taiwan’s benchmark closed barely changed Thursday after a whippy session that briefly reclaimed 45,000. All three institutional groups bought — foreign investors for a second day — even as the previous session’s futures book showed foreigners still heavily net short.
Every Taipei trading day ends with one release that sets the next morning’s narrative: the three institutional investors report.

The TAIEX rose 1.34% to 44,825.78 on Wednesday as foreign investors and investment trusts bought nearly NT$17B each — but TSMC sat out, and MediaTek, UMC and Hon Hai carried the tape.
The TAIEX surged 4.20% to 44,232.87 on Tuesday, clawing back part of Friday’s historic 6.47% rout. But the rebound was domestically funded: investment trusts bought NT$17.23B while foreign investors stayed net sellers at NT$-4.33B.
The TAIEX gave back an early bounce to close down 0.52% at 42,449.70 in the first session after Friday’s record plunge. TSMC rose on a $100B Arizona expansion, but UMC cratered 9.7%, foreigners kept selling, and investment trusts did the buying.
Taiwan’s benchmark fell 6.47% to 42,671 on Friday as an overnight 4.29% rout in the Philadelphia Semiconductor Index swept through Taipei. TSMC dropped 7.29% despite a record Q2, UMC closed limit-down, and foreign investors had already sold NT$48.3 billion of cash equities heading into the session.
