TSMC Leads Taiwan Stocks: TAIEX Vaults Nearly 1,000 Points to Reclaim 46,000

How did Taiwan's stock market open today, and what was the morning session's gain?

The Taiwan Capitalization Weighted Stock Index (TAIEX) opened at 45,500.32 points on July 13, 2026, according to Central News Agency (CNA) [E1]. The index then extended its advance through the morning session, climbing as much as 976.3 points to hit an intraday high of 46,330.91 points, allowing the market to reclaim the 46,000-point level, CNA reported [E2]. The same opening and intraday-high figures were corroborated by UDN (money.udn.com), which described the session as "opening high and moving higher" [E9], and by SETN, which reported identical data confirming the market's open-high-close-high pattern [E12].

How much did TSMC shares rise, and how did it lead the market?

TSMC, referred to in the CNA report as the market's "weighting king" (權王), rose NT$60 to close at NT$2,475 in early trading [E3]. This same price move was independently confirmed by UDN [E10] and SETN [E13], with all three outlets using near-identical language to describe TSMC's gain. Given TSMC's outsized weighting in the TAIEX, its NT$60 advance to NT$2,475 aligns directly with the broader index's nearly 1,000-point morning surge documented in E2, underscoring the stock's role as the principal driver of the day's rally.

How did other heavyweight stocks (Foxconn, MediaTek, Delta Electronics, Largan) perform today?

Beyond TSMC, several other heavyweight stocks posted notable gains in the morning session, per CNA [E4, E5, E6, E7] and corroborated by UDN's consolidated report [E11]:

Forxconn added NT$4 to reach NT$241.5 [E4, E11], MediaTek jumped NT$105 to NT$4,030 [E5, E11], and Delta Electronics gained NT$80 to NT$1,960 [E6, E11]. Largan Precision stood out by hitting its daily limit-up at the open, reaching NT$4,345 [E7, E11].

How did electronics, financial, and TPEx indices perform today?

Sector-wide, the electronics sub-index rose by more than 2%, while the financial sub-index gained 0.3%, according to CNA [E8]. The Taipei Exchange (TPEx) index, which tracks small- and mid-cap stocks, advanced 1.58% [E8]. These figures were independently repeated by SETN in its own coverage of the same trading session [E14], indicating consistent reporting of sector performance across outlets.

What this means

Taken together, the evidence shows a broad-based rally rather than a single-stock event: the TAIEX's climb from a 45,500.32-point open to an intraday high of 46,330.91 points [E1, E2] coincided with TSMC's NT$60 gain to NT$2,475 [E3], Largan's limit-up move to NT$4,345 [E7], and gains across Foxconn, MediaTek, and Delta Electronics [E4, E5, E6]. The sector data reinforces this picture—electronics stocks rising over 2% against a more modest 0.3% gain in financials [E8]—suggesting the day's nearly 1,000-point index advance was concentrated in electronics-related heavyweights rather than spread evenly across all sectors. The consistency of these figures across CNA, UDN, and SETN reporting [E1–E14] indicates the data reflects a single, well-documented trading session rather than divergent accounts.
