Nine145 Technology, Economy and Markets Desk | 16 July 2026
Taiwan Semiconductor Manufacturing Company delivered the kind of quarterly result that would normally lift an entire technology sector. Its second-quarter net profit rose 77% year-on-year to NT$706.6 billion, or approximately $21.99 billion, substantially exceeding the NT$632.6 billion consensus estimate.
Yet semiconductor shares fell across Asia and the United States.
The Philadelphia Semiconductor Index dropped more than 4% during US trading. Nvidia declined 2.5%, Micron Technology fell 5.7%, and South Korea’s KOSPI lost more than 6%. TSMC’s Taiwan-listed shares gained 1.2%, but its US-listed securities fell in early trading.
The message from the market was not that artificial-intelligence demand had disappeared. It was that expectations had risen so far that even record earnings were no longer enough to justify every AI-linked valuation.

The Market Reaction
| Market or company | Reported move | Context |
| TSMC Taiwan shares | +1.2% | Domestic investors initially rewarded the earnings result |
| TSMC US-listed shares | −2.2% | US trading reflected broader AI-sector selling |
| Nvidia | −2.5% | Largest negative weight on the S&P 500 |
| Micron Technology | −5.7% | Memory-chip valuations came under pressure |
| Sandisk | −10.6% | Sharp correction despite very large year-to-date gains |
| Western Digital | −9% | Storage and memory-related shares weakened |
| Philadelphia Semiconductor Index | More than −4% | Sector-wide decline |
| South Korea KOSPI | Approximately −6.4% | Samsung and SK Hynix carry heavy index weight |
| Japan Nikkei | Nearly −3% | Regional technology weakness spread |
| Nasdaq Composite | −0.95% at 12:13 PM ET | AI and semiconductor losses outweighed strength elsewhere |
The S&P 500 was down approximately 0.36% and the Nasdaq 0.95% at 12:13 PM ET. Reuters described the selling as global, extending from South Korea and Japan to Wall Street despite TSMC’s 77% earnings growth.
Why Record Earnings Were Not Enough
| Market concern | Explanation |
| Valuations already discount rapid growth | Investors may have priced several years of AI expansion into present share prices |
| Capital spending is enormous | Data centres, fabs, power systems and advanced packaging require sustained investment |
| Profitability of AI customers remains uneven | Chip demand can remain high even while downstream AI applications struggle to earn profits |
| Memory and processor prices may be cyclical | Present shortages could eventually produce excess supply |
| Interest rates remain elevated | Higher bond yields reduce the present value of distant technology earnings |
| Market concentration is extreme | A small group of AI-linked companies has an outsized effect on national and global indices |
| Expectations require continuous outperformance | A result that is excellent in absolute terms can disappoint if investors expected something even stronger |
AI-linked stocks had already registered extraordinary gains. AP noted that even after their latest declines, Micron remained up almost 200% for the year, Sandisk around 500% and Western Digital approximately 170%.
This explains the apparent contradiction. Investors were not disputing TSMC’s earnings. They were reassessing the price they were willing to pay for future earnings across the entire AI supply chain.
South Korea Shows How AI Is Moving from Markets to Monetary Policy
The Bank of Korea unanimously raised its benchmark rate by 25 basis points, from 2.50% to 2.75%. It was the country’s first increase in approximately three and a half years.
The central bank linked the decision to three factors: stronger economic growth, persistent inflation and financial-stability risks. It specifically identified the semiconductor sector as a driver of exports, investment and domestic demand.
| Bank of Korea indicator | Latest position |
| Base rate before decision | 2.50% |
| Base rate after decision | 2.75% |
| Decision | Unanimous |
| June consumer inflation | 3.2% |
| Core inflation | 2.5% |
| Inflation target | 2.0% |
| Previous 2026 growth forecast | 2.6% |
| New guidance | Growth expected to considerably exceed 2.6% |
| June exports | More than $100 billion |
| Household loan growth | Approximately ₩8–9 trillion per month |
| Lending-support programme rate | Raised from 1.00% to 1.25% |
South Korea’s exports exceeded $100 billion in June for the first time, with information-technology exports continuing to register triple-digit growth. The central bank said the resulting rise in company profits, wages, investment and tax revenue would support domestic demand but also increase underlying inflationary pressure.
The AI Growth–Inflation–Rate Cycle
| Stage | Economic mechanism |
| 1. Global AI investment rises | Technology companies order more processors, memory and networking equipment |
| 2. Semiconductor exports expand | Manufacturing economies such as South Korea and Taiwan receive stronger export income |
| 3. Corporate profits and investment increase | Companies expand factories, equipment and hiring |
| 4. Wages and tax receipts improve | Domestic purchasing power rises |
| 5. Demand-side inflation strengthens | Consumer and property-market demand becomes more persistent |
| 6. Central banks raise interest rates | Policymakers attempt to prevent inflation and asset-price overheating |
| 7. Higher rates pressure technology valuations | Long-duration growth stocks become less attractive |
| 8. Markets demand stronger earnings | Even record profits may not prevent a sell-off |
This is the larger significance of the 16 July events. The AI boom is no longer only a technology story. It is influencing national exports, currencies, housing markets, household debt and central-bank policy.
South Korea’s Particular Concentration Risk
Samsung Electronics and SK Hynix dominate South Korea’s equity market to an extent that makes the KOSPI unusually sensitive to semiconductor sentiment. When both companies decline, the entire national index can fall even if other sectors remain stable.
| Concentration effect | Consequence |
| Large chipmaker index weights | Semiconductor selling produces an exaggerated benchmark decline |
| Retail use of leveraged products | Volatility can trigger forced liquidation |
| Foreign-investor ownership | Global portfolio rebalancing rapidly affects the won and equities |
| Export dependence | Chip prices influence national growth and tax revenue |
| AI-cycle expectations | Corporate results become proxies for the entire economy |
| Strong earnings but falling shares | Market confidence can weaken without a fall in real activity |
The KOSPI’s decline therefore does not necessarily show that South Korea’s economy weakened on 16 July. The Bank of Korea reached the opposite conclusion: growth had strengthened enough to justify tighter monetary policy. The market was correcting valuation, while the central bank was responding to economic expansion.
Is This the End of the AI Boom?
The available evidence does not support that conclusion.
TSMC’s 77% profit growth, expanding capital expenditure and higher long-term manufacturing commitments indicate continuing demand. South Korean exports and investment provide further evidence that the hardware cycle remains strong.
The more defensible conclusion is that the AI trade has entered a more demanding phase.
| Earlier AI-market phase | Emerging phase |
| Revenue growth rewarded automatically | Revenue must exceed already exceptional expectations |
| Capital spending treated as expansion | Investors examine returns on each dollar invested |
| Chip shortages supported all suppliers | Product mix and pricing power matter more |
| High valuations tolerated | Interest rates and cash flow receive greater attention |
| Broad AI label lifted stocks | Markets differentiate between profitable infrastructure and speculative applications |
| Long-term potential dominated debate | Near-term monetisation becomes increasingly important |
What to Watch Next
The next indicators will include Nvidia and major US technology-company earnings, TSMC’s order visibility, advanced-packaging capacity, memory-chip prices, data-centre capital expenditure and the Bank of Korea’s next inflation and GDP readings.
A continued rise in semiconductor revenue accompanied by falling share prices would confirm that valuation compression—not an earnings recession—is driving the correction. A slowdown in orders would represent a more fundamental change.
For now, the central finding is unusually clear: the AI economy is still expanding rapidly, but the AI stock market is no longer willing to reward expansion at any price.
