Heading for a sixth straight loss, the SOX is still up about 63% on the year
Asian chip stocks fell Tuesday after a US semiconductor sell-off, yet the SOX is still up about 63% for 2026 on our arithmetic. The KOSPI fell more than 6%, Reuters reported; the evidence so far points to financing strain.
The Investor · Invest desk
Key figures: the SOX would need a further fall of about 38.8% from Tuesday's level to erase its gain for the year. It fell 2.7% on Tuesday. Coming into Tuesday it had posted a 68% gain for the year.
| Figure | Value | Note | Claim |
|---|---|---|---|
| Further SOX fall that would erase its year gain, about | 38.8% | 23 | |
| SOX fall on Tuesday | 2.7% | 2 | |
| SOX year gain into Tuesday | 68% | 10 |
What happened
- The SOX was heading toward a sixth straight losing session, its worst stretch in about 16 months, according to MarketWatch as relayed by Quartz.
- Firmus, an Nvidia-backed data center company, pulled a planned $5 billion Australian IPO last week after failing to draw enough investor demand, Reuters reported.
- BlackRock moved its US equities stance to neutral on Monday, citing potential volatility around the AI buildout, and turned favorable on short-term Treasuries.
- Micron slid 3.9% on Monday as investors weighed competition from China's CXMT, which reported progress on a new chip structure, CNBC reported.
Why it matters
- What doesn't add up contradiction MarketWatch ties the slide to fading enthusiasm for AI spending, while CNBC reports the Intel and Broadcom chiefs saying capital access is the headwind and demand still outstrips supply.
- Who's exposed exposure A holder who began 2026 with 10% in Micron and left the rest flat now has 25% there after its tripling, so the book takes far more of each 5% down day than it was built to.
- What it limits constraint A developer seeking money for AI data centers has seen one equity deal fail and credit investors turn choosier, so capacity plans now wait on funding that costs more or does not arrive.

Hot US inflation hit a Kospi whose 55 trillion won of chipmaker buybacks had wound downConfirmed4 publishers
The index is still well up on the year. Coming into Tuesday the SOX had gained 68% [10], and if Tuesday's 2.7% fall holds into the close [2], the year's gain is 1.68 times 0.973, or about 63% [22]. Erasing the rest would take another drop of roughly 39% from there [23]. The last two sessions, each down 2.7%, took 5.3% between them [24].
Seoul and Shanghai are further down. The KOSPI is off a quarter from its July highs [13], and it would need a 33% rally to regain them [19]. The STAR Market is down more than a third from its July peak [14], so the climb back is at least 50% [20]. SK Hynix fell 8% on Monday, according to Reuters [3], and more than 8% on Tuesday, according to CNBC [4], a two-day loss of at least 15% [21].
Whether those moves reflect a change in value depends on the cause, and the quoted evidence points at money. "The most important development has been not just bond yields going up, but the volatility for bonds ... and that's starting to work its way out through asset pricing across the board," Damien Boey, portfolio strategist at Wilson Asset Management in Sydney, told Reuters [5]. The IMF's latest financial stability report warned that "the consequences of an AI correction could be global" [7], and added that there is growing evidence AI capability investments and economic gains may not be as large as expected [8].
Neither source reports a cut in chip orders or guidance. We think the record fits a financing repricing better than a break in demand, though it is thin on both.
The IMF's second point is an argument about returns, and if it is right, calmer bond markets would not bring chip shares back. Three outcomes would separate the readings. If bond volatility settles and chip shares recover, the cause was rates. If volatility settles and they keep falling, the returns argument gains weight. If chipmakers' own results cut orders or guidance, the cause is demand, and our financing reading is wrong.
What to watch
- This week's US inflation data and corporate earnings, the first readings on bond volatility and on any chipmaker order or guidance cuts.
- Anthropic's Oct. 14 investor day in San Francisco, and whether prospective investors still hold to the $1.8 trillion to $2 trillion valuation range.
- Any further AI data center deal that is pulled or repriced, or further tightening in credit for AI-related debt.
