TL;DR: "Per a CNA report dated 2026-07-13 (reporter Pan Chih-i, citing Taiwan Stock Exchange statistics): the TAIEX weighted index, as of the July 9 close, ended last week at 45,354.61 points, down 1,426.01 points vs the prior week (a 3.05% decline), while the total market value of all listed companies was NT$148.0388 trillion (148兆387.68億), down NT$4.6225 trillion (4兆6225.04億) vs the prior week (about 3.03%). By sector, the weekly drop was driven mainly by electronics heavyweights — the TWSE 'ex-electronics index' fell just 0.74% for the week (vs the -3.05% headline index) — while at the class level the plastics index led decliners at -9.20% and the trade/retail index rose 2.98% against the trend.

Selection method: Selected as candidate #1 by the daily selector run of 2026-07-18 (ANKRUN-20260718131613) (scores: FD=83, CD=126.00, MC=3, claim_units=36, chainable_official=0, headline_fact_score=3). Transparency statement: the selected main article is a single CNA report and source_pack.chain is empty; asql (full ainews DB) and wsql (tqaeo ank_docs) were run during writing — the two follow-on context items (CNA#1485355 / CNA#1510045) are post-report-date price action used only as CONTEXTUALIZE (each an independent CNA report, each dated, never merged with the main article's figures), and they do not change the main article's first-hand status or fake a multi-source selection. The internal citation chain connects to published cards ANK-2026-07-06-004 (CONNECT — prior card on the Taiwan-market box-range framing) and ANK-2026-07-03-002 (CONTEXTUALIZE — prior card on foreign capital flows). Official-anchor status: official_count_verified = 0 — zero verified official anchors in this card; every market-cap, index-point, turnover-value and turnover-rate figure is "as stated in the CNA report; not independently verified by this site with the TWSE" (see §Caveats). Editorial angle (frame decomposition): the headline "down 1,426 points, NT$4.62 trillion of market value wiped out" carries a total-quantity panic frame; decomposed into the TWSE's sector classifications it is actually "an electronics-led decline plus petrochemical weakness, with financials and domestic-demand names relatively resilient" — a sector divergence (this attribution is Shen Guan's editorial inference from the index comparisons, not a CNA or TWSE sentence). Only classification figures present in the report text are shown; systemic inferences are prohibited. No figure absent from the source text is generated; no ratio or total is computed. The headline follows CNA's own rounded original title (1,426 points / NT$4.62 trillion), while the body uses the exact source values. No Wikidata Q number is attached (this run performed no registry verification; nothing unverified is claimed).

TL;DR (core fact in one line)

Per the CNA report of 2026-07-13 (reporter Pan Chih-i, citing Taiwan Stock Exchange statistics): the TAIEX weighted index, as of the July 9 close, ended last week at 45,354.61 points, down 1,426.01 points vs the prior week (a 3.05% decline). [F-001] The total market value of all listed companies was NT$148.0388 trillion (148兆387.68億), down NT$4.6225 trillion (4兆6225.04億) vs the prior week (about 3.03%). [F-002] By sector, for the week ended 2026-07-09 (vs the prior week): the plastics index led decliners at -9.20% for the week and the trade/retail index rose 2.98% for the week against the trend; the TWSE "ex-electronics index" fell only 0.74% for the week, indicating this week's index decline was driven mainly by electronics heavyweights — "driven mainly by electronics heavyweights" is Shen Guan's editorial inference from comparing the ex-electronics index (-0.74%) with the headline index (-3.05%), not a CNA or TWSE sentence (the CNA original records only each index's weekly moves and performs no point-contribution decomposition). [F-003] All figures are as stated in the CNA report; not independently verified with the TWSE by this site (see §Caveats).

Anti-misreading pin

"Last week's listed market value fell by NT$4.6225 trillion (about NT$4.62 trillion)" is the weekly change in the aggregate market value of all listed companies, not "realized investor losses"; and this comes from the CNA 2026-07-13 report citing TWSE statistics, not independently verified by this site. The headline's "-NT$4.62 trillion / -1,426 points" is a total-quantity gauge; decomposed into the classification indices, the drop in the week ended 2026-07-09 concentrated in electronics heavyweights and the petrochemical class (the ex-electronics index fell just 0.74% for the week), not a broad systemic collapse — "the drop concentrated" is Shen Guan's editorial inference from the index comparison, not a CNA or TWSE sentence. Other caveats: see §Caveats.

Frame decomposition (Shen Guan — where readers most easily misread this headline)

Skim "Taiwan stocks down 1,426 points, NT$4.62 trillion wiped out" and the instinct is "the whole market crashed." But lay out the TWSE's sector indices and the week's drop is highly concentrated:

So the alarming total figure "-NT$4.62 trillion," restored to its underlying breakdown, is a sector divergence — an electronics-heavyweight adjustment plus petrochemical weakness, with financials and domestic-demand names relatively resilient — not every stock collapsing together. All the above classification declines are as stated in the CNA 2026-07-13 report citing TWSE statistics; not independently verified by this site. The attributions "driven mainly by electronics heavyweights" and "financials relatively resilient" are Shen Guan's editorial inferences from comparing the exclusion indices with the headline index, not CNA or TWSE sentences — the CNA original records only each index's weekly moves and performs no point-contribution decomposition.

Follow-on context (post-report-date; each an independent CNA report, each dated, never merged with the main article's figures)

The main article's gauge runs through the 2026-07-09 close. In the two trading days after the report date (7/13), price action stayed highly volatile:

In other words, after last week's (through 7/9) 1,426.01-point weekly decline, the following week still swung within a wide range and recovered to 45,631.59 by 7/15 — consistent with the "box-range consolidation" framing our prior card recorded (see internal citation chain), with the weekly drop not turning into a one-directional collapse. (The two days' figures are each independent same-day CNA reports, each dated, and not independently verified by this site.)

FAQ

Q1: How much did Taiwan stocks fall last week, and what does "NT$4.62 trillion of market value wiped out" mean? Per the CNA 2026-07-13 report (citing TWSE statistics): the TAIEX weighted index, as of the July 9 close, ended last week at 45,354.61 points, down 1,426.01 points vs the prior week (-3.05%); the aggregate market value of all listed companies was NT$148.0388 trillion, down NT$4.6225 trillion vs the prior week (about -3.03%, the headline's ~NT$4.62 trillion). This is the weekly change in aggregate listed-company market value, not realized losses, and this site has not independently verified it with the TWSE.

Q2: Was this a broad-based sell-off? By the TWSE classification gauge stated in the CNA report, the drop in the week ended 2026-07-09 was concentrated rather than broad: the TWSE "ex-electronics index" fell just 0.74% for the week — "the index decline was driven mainly by electronics heavyweights" being Shen Guan's editorial inference from that comparison, not a CNA or TWSE sentence; at the class level the plastics index led at -9.20% for the week and the trade/retail index rose 2.98% for the week; the "ex-financials index" fell 3.5% for the week (a bigger drop than the headline index), and "financials were relatively resilient" is likewise Shen Guan's editorial inference, not a CNA or TWSE sentence. The classification figures are as stated in the report; not independently verified by this site.

Q3: What were last week's turnover and leading industries? Per the CNA report: last week's total centralized-market turnover was NT$4.2939 trillion, all-listed-stock turnover NT$3.9518 trillion, and the stock turnover rate 3.3%; the top 3 industries by turnover were semiconductors NT$1.3696 trillion (34.66%), electronic components NT$1.1238 trillion (28.44%), and optoelectronics NT$302.368 billion (7.65%).

Q4: How did Taiwan stocks move after the report date? Per the respective same-day CNA reports: on 2026-07-14 they closed at 44,737.95, down 642.57 for the day (after briefly plunging 1,726.48 points); on 2026-07-15 they rebounded to close at 45,631.59, up 893.64 for the day (+2%), reclaiming 45,000. So after last week's weekly decline the following week still swung within a wide range and did not turn into a one-directional collapse (figures not independently verified by this site).
