Taiwan Stock Market Hits All-Time High as AI Bear Case Is Refuted by Semiconductor Data
nashnova research
Taiwan's TWSE broke to a record high while foreign investor positioning remains light — IC revenue is forecast to jump another 41% in 2026, and hard semiconductor data is directly contradicting the "AI has peaked" narrative.
Foreign investors are still underweight — so who is driving the rally?
The TWSE pushed past its prior record, yet foreign investor positioning remains near lows — some institutions read this combination as a bullish signal.
This means → the current rally is mostly domestic- and retail-driven. Foreign buying power has not yet entered in size.
Retail sentiment is running hot: margin balances have risen for 10 straight trading days. TWSE margin is within 0.2% of its all-time high; TPEx margin has already set a new record.
In plain terms = retail traders are adding leverage, but relative to market cap the level is still below the July 2024 peak — there is room for sentiment to stretch further.
Why does the hard semiconductor data undercut the "AI has peaked" thesis?
Taiwan IC revenue grew roughly 23% in 2025; the market expects a further 41% jump in 2026 — these are shipment-level figures, not concept hype.
Franklin Templeton data shows consensus expects Taiwan-listed companies to deliver EPS growth above 50% in 2026.
This means → if AI demand were truly collapsing, chip-company revenue and earnings estimates could not both be revised sharply higher at the same time. The hardware numbers and the bearish narrative point in opposite directions.
What does TSMC — the key verification node — tell us?
Per J.P. Morgan, TSMC's AI-accelerator demand is strong. N3/N5 utilization exceeds 100%, and EPS estimates keep moving up.
TSMC disclosed that customer engagement on leading-edge nodes now starts at least two to three years in advance — this reflects multi-year capacity lock-ins, not a short-term pulse.
In plain terms = customers are not "testing the waters" on AI chips — they are queuing up years ahead for capacity. That directly challenges the "AI demand is about to collapse" story.
J.P. Morgan also flagged that capex-downside risk is not yet priced into hardware stocks — the market may be underestimating the impact of a bear scenario.
Beyond AI, what can the Apple upgrade cycle add?
J.P. Morgan estimates roughly 55% of the TWSE's market cap has positive exposure to Apple.
Historically, in the three months after a major Apple product upgrade, Taiwan supply-chain forward EPS estimates are revised up by an average of about 9%.
This means → AI is the main thread, but the Apple replacement cycle could become a second earnings catalyst — stacking both lines creates a dual tailwind for Taiwan semis.
How is the trade being positioned?
J.P. Morgan recommends buying December 2026 call options struck at 110% of the TWSE index level.
The rationale: Taiwan equity implied volatility — the market's priced-in expectation of future swings — has pulled back from its recent peak, making outright upside calls more cost-effective.
This reflects an institutional view that current market pricing is conservative, and betting on further upside via options is relatively cheap.
Where is the next verification window?
Light foreign positioning is the key structural pillar of the current bull case — if the AI hardware cycle keeps delivering, foreign re-allocation becomes the main driver of the next leg higher.
In plain terms = the logic chain runs: strong semi data → foreign confidence rebuilds → capital flows back → next wave of gains.
The verification window centers on TSMC's and its supply chain's quarterly earnings — those numbers will determine whether the "AI hardware cycle" keeps delivering or starts to crack.
