Selection method: Ranked No. 1 by the daily selector (ANKRUN-20260722193705; scores: FD=97, CD=291.00, MC=3, claim_units=97, chainable_official=0, official_count_verified=0, headline_fact_score=3). Transparency statement: the selected main article is a single Storm Media post-close flash with an empty source_pack.chain; the other 13 articles were added from the full library at writing stage, each labeled with its report date and linking layer, without disguising the selection as multi-source. Official-anchor scope: official_count_verified=0; the card-wide media-figure scope is consolidated in the Scope section and is not repeated here (see Scope). Editorial angle (fact-pinning): this card pins the 592.91-point follow-through gain of July 22, 2026 back onto the full three-session event chain (July 20 close 42,449.70 → July 21 up 1,783.17 points, the largest-ever single-day closing gain → July 22 up 592.91 points to 44,825.78), citing each day's figures from that day's own reports with their own attributions; sector moves are pinned down to individual closing prices and percentage changes, and fund flows down to the itemized amounts and lot counts of the three institutional groups. The international chain (US memory stocks, Korea's sidecar halt) is presented as parallel context only, with no causal inference. No figure absent from the source texts is generated; no ratios or differences are independently computed; figures from different sources are kept in separate sentences with separate attributions. No Wikidata Q identifiers are attached (no registry verification was performed this shift; better absent than unverified).
TL;DR
Storm Media's post-close report of July 22, 2026: Taiwan's TAIEX opened at 44,513.75 on July 22, 2026, touched an intraday high of 45,323.75, and closed at 44,825.78, up 592.91 points (1.34%) from the previous trading session, July 21, 2026 (storm#1643517; CNA cna#1643365 and Anue cnyes#1643136 reported the same closing figures the same day). [F-001] Turnover was NT$982.645 billion (NT$9,826.45 hundred-million as reported; unit conversion marked in Scope), which Anue described as a third consecutive session (July 20–22, 2026) below NT$1 trillion (cnyes#1643136, cna#1643365). [F-002] Gains were led by memory (Nanya Technology limit-up at NT$445.5), PCB (Unimicron up 9.94%) and AI-server/high-priced stocks (Wiwynn and ASPEED limit-up); aerospace and defense shares slumped (AIDC down 9.93%) (storm#1643517). [F-005][F-006][F-007][F-008] Flows: the three major institutional groups bought a combined net NT$31.938 billion on July 22, 2026 (cna#1643637); foreign investors bought a net NT$17.343 billion, ending what CNA described as a 13-consecutive-session selling streak (cna#1646181). [F-009][F-010] Event chain: on July 21, 2026 the TAIEX rose 1,783.17 points, its largest-ever single-day closing gain (reported independently by CNA cna#1628181 and PTS media_tw#1637878); on July 20, 2026 it closed at 42,449.70, down 221.57 points from the previous session (cna#1613945).

Each day's figures are cited from that day's own reports with their own attributions; this card computes no cross-day differences or cumulative totals. "Largest-ever single-day closing gain" is the record wording carried by CNA and PTS on July 21, 2026 (CNA also reported that day's intraday gain as the second-largest on record, cna#1628181). [F-011][F-013]
Body
The July 22, 2026 session: higher open, intraday high of 45,323.75, close at 44,825.78
Storm Media's post-close flash of July 22, 2026: the TAIEX opened at 44,513.75, briefly touched 45,323.75 intraday, and finished at 44,825.78, up 592.91 points (1.34%) from the previous trading session, July 21, 2026 (storm#1643517). Anue reported the same day that the index opened up 280.88 points and was up as much as 1,090 points (vs. the previous session's close) in the morning, reclaiming the 45,000 level, before TSMC turned negative and the gain narrowed (cnyes#1643136). [F-001][F-002]
Technical levels (as reported): CNA reported on July 22, 2026 that the close reclaimed the 10-day moving average (around 44,664) (cna#1643129); a separate CNA piece put the monthly moving average at around 45,360 (cna#1643365). [F-003]
Heavyweights (July 22, 2026 close, vs. the previous session): TSMC fell NT$10 (-0.41%) to NT$2,400; MediaTek rose NT$180 (+4.9%) to NT$3,850; Delta Electronics rose NT$45 (+2.45%) to NT$1,880; Hon Hai (Foxconn) rose NT$5.5 (+2.24%) to NT$251.5 (cna#1643365, cna#1643129). [F-004] Storm Media also noted that financial heavyweight Fubon Financial steadied the market that day (no closing figure given in the source; this card adds none) (storm#1643517).
Leading sectors: memory, AI servers and high-priced stocks, PCB (pinned to individual names)
All individual prices and percentage changes below are July 22, 2026 closes versus the previous trading session (July 21, 2026), as tabulated in Storm Media's post-close report (storm#1643517):
- Memory: Nanya Technology (2408) NT$445.5 (+NT$40.5, +10.00%, limit-up); Winbond (2344) NT$171 (+NT$15.5, +9.97%); Macronix (2337) NT$135 (+NT$12, +9.76%). [F-005] CNA's same-day wrap phrased it as "Nanya Technology, Winbond and Macronix hit limit-up," and added that DRAM module makers ADATA, Transcend, Apacer, Team Group and Silicon Power each gained more than 2% that day (cna#1643365) — the two outlets differ slightly on whether Winbond and Macronix closed at or just below limit-up; this card records both wordings without adjudicating (see Scope). [J-003]
- AI servers and high-priced stocks: Wiwynn (6669) NT$5,500 (+NT$500, +10.00%, limit-up); ASPEED Technology (5274), Taiwan's highest-priced stock, NT$15,510 (+NT$1,410, +10.00%, limit-up); Wistron (3231) NT$164 (+NT$14.5, +9.70%) (storm#1643517). CNA's wording: ASPEED's limit-up energized the high-price segment, with Wiwynn, eMemory (力旺), LandMark Optoelectronics (聯亞), 光聖, Taiwan Union Technology (台燿), Nan Ya PCB, 昇達科, 高力 and other NT$1,000-plus stocks at limit-up, and "the number of NT$1,000-plus stocks recovered to 49 today" (July 22, 2026; the prior day's count was not given in the source) (cna#1643365). [F-006]
- PCB: Unimicron (3037) NT$907 (+NT$82, +9.94%); Zhen Ding-KY (4958) NT$559 (+NT$50, +9.82%); Nan Ya PCB (8046) NT$1,305 (+NT$115, +9.66%); Taiwan Union Technology (6274) NT$1,355 (+NT$120, +9.71%) (storm#1643517). Passive components: CNA reported sector leader Yageo (2327) up nearly 9% at its intraday peak on July 22, 2026, closing up NT$33 (+4.93%) at NT$703 (cna#1643365); Anue reported Walsin Technology, 鈺邦, 大毅, 華容 and others at limit-up that day (cnyes#1643136). [F-007]
Volume: Storm Media's table put Innolux (3481) first by volume on July 22, 2026 at 288,449 lots (1,000 shares per lot), closing at NT$52.5 (+NT$1.8, +3.55% vs. the previous session) (storm#1643517). Anue also reported multiple limit-ups that day in silicon photonics names (光聖, 聯亞, Browave, 立碁 and others) and industrial PC names (樺漢, 凌華) (cnyes#1643136). [F-002]
The slumping sector: aerospace and defense — the full contrast with the previous session
July 22, 2026 closes versus the previous session (Storm Media table, storm#1643517): AIDC (Aerospace Industrial Development Corp, 2634) NT$64.4 (-NT$7.1, -9.93%); Air Asia Co. (2630) NT$53.2 (-NT$5.7, -9.68%); Evergreen Aviation Technologies (2645) NT$195 (-NT$20, -9.30%); Thunder Tiger (8033) NT$196.5 (-NT$17.5, -8.18%). [F-008] AIDC was also foreign investors' single largest net sell that day at 27,578 lots (cna#1646181). [F-010]
Contrast with the previous session: CNA reported on July 21, 2026 that AIDC closed limit-up at NT$71.5 on heavy volume that day (July 21, 2026), with multiple other defense names also at limit-up — Air Asia Co., Lungteh Shipbuilding and others (寶一, 晟田, 事欣科, 融程電); the same article carried AIDC's own statement that it had won NT$12.8 billion in new orders in the first half of 2026 (company statement, not officially verified) (cna#1628184). [F-016] Separately, CNA reported on July 22, 2026 that AIDC announced an agreement with US-based Moog extending its US subsidiary's exclusive Taiwan distributorship to 2031 (announced on day two of the Farnborough International Airshow, held July 20–26, 2026) (cna#1642510). [F-017] A cooperation announcement and a sharp share-price fall occurred on the same day — this card presents the two verifiable facts side by side and draws no causal inference between them (see Scope). [J-002]
Flows: institutions bought a combined net NT$31.938 billion; foreign investors ended a 13-session selling streak
CNA, July 22, 2026: the three major institutional groups bought a combined net NT$31.938 billion that day — foreign investors (including mainland-China-sourced funds) a net buy of NT$17.343 billion, investment trusts a net buy of NT$16.992 billion, and dealers a net sell of NT$2.397 billion (cna#1643637). [F-009] A separate CNA piece the same day: foreign investors (excluding foreign dealers) bought a net NT$17.343 billion on July 22, 2026, ending what the report described as a 13-consecutive-session selling streak; their top three net buys that day were the actively managed Taiwan equity ETFs 00403A (主動統一升級50) at 121,004 lots and 00981A (主動統一台股增長) at 52,626 lots, plus Yuanta Taiwan 50 Bull 2X (00631L) at 46,261 lots — the top two both actively managed Taiwan equity ETFs; the top three net sells were AIDC at 27,578 lots, 1718 (中纖) at 22,087 lots and ChipMOS (8150) at 15,132 lots (cna#1646181). [F-010]
Analyst view (quoted, not a fact anchor): Liao Chi-hung, investment director at Concord Securities, said in CNA's July 22, 2026 reports that the epicenters of the recent Taiwan pullback included deleveraging in Korean semiconductor stocks, China's open-source AI model Kimi K3 and the Philadelphia Semiconductor Index's slide, and that after the correction major investment banks broadly saw no major change in AI-industry fundamentals; he added that after breaking below the quarterly moving average on July 17, 2026 (the prior Friday), the index had quickly reclaimed it this week, with the next hurdle at the monthly moving average around 45,360 (cna#1643365, cna#1646181 — analyst opinion, not official figures). [J-002]
The event chain and the international chain: around July 21's record closing gain
July 21, 2026 (previous session): CNA reported the TAIEX finished up 1,783.17 points at 44,232.87 that day, setting the largest-ever single-day closing gain and the second-largest intraday gain on record, breaking above quarterly-moving-average resistance (43,709); turnover fell to NT$835.624 billion (vs. the previous session, July 20, 2026); TSMC rose NT$90 to NT$2,410 and MediaTek closed limit-up, up NT$330 at NT$3,670 (cna#1628181). [F-011] Taiwan's Public Television Service (PTS) independently reported the same record the same day — "TAIEX closes up 1,783 points, largest gain on record" — adding that Korea's KOSPI closed up more than 3% that day led by Samsung Electronics, with a buy-side program-trading pause briefly triggered intraday, and that Japanese stocks rose more than 1,000 points intraday, returning to around the 65,000 level (media_tw#1637878) — two independent outlets cross-confirming the July 21, 2026 record. [F-012]
July 20, 2026 (chain start): CNA reported the TAIEX closed at 42,449.70 that day, down 221.57 points (-0.52%) from the previous session, with an intraday high-low swing of more than 1,100 points and turnover of NT$983.863 billion; Nanya Technology fell 3.67% to NT$381 and Winbond fell 2.58% to NT$151 that day (cna#1613945). [F-013]
US stocks (US Eastern time, July 21, 2026 session): per CNA's Washington dispatch, SK Hynix ADRs jumped 13.75% and Micron 12.17%; the Philadelphia Semiconductor Index rose 5.21%, the Nasdaq 1.29%, the Dow 0.74% and the S&P 500 0.89%; TSMC ADRs rose 5.55%, Intel 8.64% and AMD 8.11% (all single-day moves for the US session of July 21, 2026, Eastern time) (cna#1640435). CNA's Taipei post-close wrap likewise cited the SK Hynix ADR and Micron gains as context for Taiwan memory stocks' strength that day (cna#1643365). [F-014]
Korean stocks (July 22, 2026): Anue reported the KOSPI reclaimed the 7,000 mark that day and was up more than 6% intraday (single-day-change basis) above 7,100; SK Hynix was up more than 9% and Samsung Electronics more than 6% intraday; with KOSPI 200 futures up more than 5% for over a minute, the Korea Exchange triggered its sidecar mechanism at 9:06 a.m. local time on July 22, 2026, halting program buy orders for five minutes (cnyes#1641538). [F-015] The international chain is presented as parallel, verifiable fact only; this card does not write it as a causal attribution for Taiwan's gains (see Scope). [J-002]
Wiwynn/Wistron background (July 20, 2026): Anue reported that foreign brokerages raised their 2026 AI-server shipment outlooks and earnings estimates for Wistron and Wiwynn — with brokerage estimates lifting Wistron's full-year NVIDIA NVL72 rack shipments to roughly 18,500 racks and revising its fourth-quarter VR200 shipments up to 1,000 units (all foreign-brokerage estimates, neither company announcements nor confirmed results) (cnyes#1613636). [F-018]
Scope (source limitations, consolidated)
- Zero verified official anchors: the selector flagged official_count_verified=0 and official_count_raw=0 for this run. Every index level, stock price and percentage change, turnover figure, institutional flow, and KOSPI/US figure in this card is as reported by Storm Media (2026-07-22), CNA (2026-07-20/21/22), Anue (2026-07-20/22) and PTS (2026-07-21) on the respective dates; this site has not independently verified any figure with the Taiwan Stock Exchange, the Korea Exchange or any other official body, and nothing here constitutes official endorsement. The Taiwan Stock Exchange's official post-close statistics are independently checkable; this shift did not perform that check (see P-001).
- Time bases: all July 22, 2026 changes are versus the previous trading session (July 21, 2026); July 21, 2026 changes are versus July 20, 2026; July 20, 2026 changes are versus the previous session (Friday, July 17, 2026); US figures are for the single US session of July 21, 2026 (Eastern time); KOSPI figures are for July 22, 2026. Individual-stock changes are closing-basis unless explicitly marked "intraday."
- "Limit-up" convention and wording differences recorded: "limit-up" is the market shorthand for Taiwan equities' 10% daily upward price limit. Winbond (+9.97%) and Macronix (+9.76%) appear in Storm Media's table as "near limit-up," while CNA's wrap says they "hit limit-up" — the two outlets' wordings are recorded as-is; this card displays Storm Media's precise percentages and does not adjudicate. Yageo's "up nearly 9% intraday" versus "closed +4.93%" are two separate bases (intraday vs. close) from the same article and are not mixed.
- Estimates and quotations: the Wistron/Wiwynn shipment and earnings figures are foreign-brokerage estimates (cnyes#1613636), not company announcements or realized results; AIDC's "NT$12.8 billion in first-half new orders" is a company statement (cna#1628184); remarks by analysts such as Liao Chi-hung are personal analysis, not official figures.
- Streak wording: "ending a 13-consecutive-session selling streak" and "third consecutive session below NT$1 trillion" are the wordings of CNA and Anue respectively; this card did not retrace those streaks day by day, though the three sessions' turnover figures (NT$983.863 billion / NT$835.624 billion / NT$982.645 billion) each carry their own attribution and are each below NT$1 trillion.
- Format transcription: conversions from the Chinese-language unit 億 (hundred million) to billions are fixed-ratio format transcriptions (1 billion = 10 億); the underlying figures are unchanged and the conversion is marked here.
- Related draft: this site's card on the July 21, 2026 record closing gain by Shen Guan (ANK-2026-07-22-003) is an unpublished draft under review; per internal-link discipline no link is set. Internal links in this card go only to published cards (see Internal citation chain).
- Chronology: this card's publication date, 2026-07-22, is on or after the latest source date, 2026-07-22 (cna#1646181, 2026-07-22 17:37 JST). Apart from the marked format transcriptions above, this card generates no new figures and computes no ratios, differences or totals.

J-Units
J-001: Official-anchor scope (see Scope): all 14 sources of this card are media reports (counting rule: one count per article in the frontmatter sources list, with each article from the same outlet counted separately — Storm Media 1, CNA 9, Anue 3, PTS 1, total 14) with official_count_verified=0; every index level (44,825.78 / 592.91 / 1,783.17 / 42,449.70 etc.), stock price and percentage change, turnover (NT$982.645 billion etc.) and institutional flow (NT$31.938 billion / NT$17.343 billion etc.) is "as reported by media, not independently verified by this site with the Taiwan Stock Exchange or other official bodies" — any citation of this card's figures must carry this scope note and must not be treated as official endorsement - confidence: high - basis: news_aggregation
J-002: Layer labels and inference limits: the same-day pieces are CORROBORATE + ADD_EVIDENCE (Storm Media / CNA / Anue closing figures cross-consistent); July 21 and July 20, 2026 are CONNECT (event chain; each day's figures carry their own attribution; no cross-day differences computed); US stocks, Korean stocks, the defense-sector contrast and the Wiwynn/Wistron outlook are CONTEXTUALIZE — between the international chain and Taiwan's moves, and between the AIDC–Moog news and the same-day share slump, this card only juxtaposes verifiable facts and infers no causation; brokerage estimates, company statements (AIDC's NT$12.8 billion in new orders) and analyst remarks (Liao Chi-hung) are each labeled by nature and none are official figures - confidence: high - basis: news_aggregation
J-003: Wording differences recorded: Winbond (+9.97%) and Macronix (+9.76%) appear in Storm Media's July 22, 2026 post-close table as near limit-up, while CNA's same-day wrap says "Nanya Technology, Winbond and Macronix hit limit-up" — this card displays Storm Media's precise percentages and records both wordings without adjudicating; Yageo's "up nearly 9% intraday" (intraday) versus "closed +4.93% at NT$703" (close) are two bases from the same article, kept separate and not mixed - confidence: high - basis: news_aggregation
P-Units
P-001: The Taiwan Stock Exchange's official post-close statistics (index close, turnover, three institutional groups' flows) are independently checkable on the exchange's site — not performed this shift (REVIEW_ONLY); the whole card keeps the "as reported by media" scope; official-anchor verification is left to follow-up (open) ### P-002: The battle around the monthly moving average (~45,360, per CNA) and whether foreign investors' July 22, 2026 switch to net buying continues are to be tracked via subsequent daily reports; this card makes no forecast (open)

All from Storm Media's July 22, 2026 post-close table (storm#1643517); the Winbond/Macronix wording difference between outlets is recorded as-is (see Scope).
Q: Who was buying on July 22, 2026 — what were institutional and foreign flows?
Per CNA, July 22, 2026: the three institutional groups bought a combined net NT$31.938 billion — foreign investors +NT$17.343 billion (ending what CNA described as a 13-consecutive-session selling streak), investment trusts +NT$16.992 billion, dealers -NT$2.397 billion; foreign investors' top two net buys were actively managed Taiwan equity ETFs (00403A at 121,004 lots, 00981A at 52,626 lots), and their largest net sell was AIDC at 27,578 lots.
(cna#1643637, cna#1646181; the streak count is CNA's wording, not retraced by this card; see Scope.)
Q: What happened in the two sessions before this rebound?
Event chain (each day with its own source): on July 20, 2026 the TAIEX closed at 42,449.70, down 221.57 points from the previous session, with an intraday swing above 1,100 points (cna#1613945); on July 21, 2026 it surged 1,783.17 points to 44,232.87 — the largest-ever single-day closing gain (intraday gain second-largest on record) — breaking above the quarterly moving average at 43,709 (cna#1628181, independently corroborated by PTS media_tw#1637878); on July 22, 2026 it added another 592.91 points to 44,825.78 (storm#1643517).
Each day's figures are cited from that day's reports; this card computes no cross-day totals (see Scope).
Q: Have this card's figures been verified with the Taiwan Stock Exchange?
No. official_count_verified=0: every figure is as reported by Storm Media, CNA, Anue and PTS on the respective dates; this site has not independently verified them with the Taiwan Stock Exchange, the Korea Exchange or any other official body, and nothing here constitutes official endorsement (see Scope).
The exchange's official post-close statistics are independently checkable; this shift did not perform that check (see P-001; any citation must carry the "as reported by media" scope note).
