TSMC Q3 Earnings Today at 3 PM KST: NT$1.49T Revenue Confirmed, N2 Ramp and Margins Are the Deciding Factors — 8 Semiconductor Stories for October 15

Yesterday (October 14), global semiconductor markets showed the paradox of "great earnings, bad stocks." ASML posted its biggest quarter ever and warned that 2027–2028 supply will fall short of demand — and still fell 3.9%. US September CPI came in hotter than expected, and the Philadelphia Semiconductor Index dropped for a sixth straight session. Today (October 15) at 3 PM KST, TSMC reports Q3 earnings — the next decision point in the AI capex debate. Here are the 8 stories to read this morning.

1. TSMC Q3 Earnings Today at 3 PM KST… NT$1.49T Revenue Confirmed

TipRanks, 2026-10-13

• TSMC reports third-quarter earnings on October 15. The conference call runs 2:00–3:30 AM ET, which is 3:00–4:30 PM today in Korea.
• Q3 revenue is already locked in: NT$1.49 trillion (about $46.7 billion), up 50% year over year, above the high end of its own guidance ($44.6–45.8 billion) and above the market consensus of NT$1.46 trillion.
• Wall Street expects EPS of $4.41 per ADR (vs. $2.85 a year ago) and net profit to surge about 64% to NT$740.8 billion.

Chase's take: The real question in this report is not the "numbers" but "2027 demand visibility." Whether management's commentary repeats the "customers asking about 2029–2030 slots" line from the ASML print will decide the next round of the AI capex debate. The revenue beat is already priced in.

2. ASML Posts Record Q3, Stock Still Falls 3.9%… "2027–2028 Supply Won't Meet Demand"

NeoTeo, 2026-10-14

• ASML reported Q3 revenue of €11.662 billion, net income of €4.960 billion and a gross margin of 57.5% — all near record levels. It shipped 113 new lithography systems.
• Q4 guidance calls for revenue of €14.2–15.2 billion, which would be the strongest quarter in company history. Full-year 2026 revenue guidance was raised to €44–45 billion.
• CEO Christophe Fouquet said planned 2027 and 2028 supply of EUV and DUV systems "will not fully meet customer demand," and the company is studying additional 2028 capacity. Some customers are already asking about 2029–2030 slots.

Chase's take: Demand is confirmed, yet the stock fell — meaning the market is now focused on "price," not "demand." When good news can't lift a sector, the valuation debate runs the market, not the numbers.

3. US September CPI at 3.7%, Above Expectations… October Hike Odds Jump Past 40%

ChosunBiz, 2026-10-14

• US September CPI rose 3.7% year over year, above the 3.6% consensus and accelerating from 3.4% in August. Month over month, prices rose 0.6%.
• Core CPI came in at 2.6% YoY and 0.3% MoM, both above expectations. Gasoline surged 9.1% on the month, accounting for more than half of the headline increase.
• CME FedWatch odds of an October FOMC hike jumped to 41–46%, from about 22% the day before. The 10-year Treasury yield held in the 5.2% range.

Chase's take: It's macro, not chip news, that sets valuations. Higher-for-longer rates directly raise the financing cost of AI capex — read this alongside the Broadcom CEO's "casino" comment.

4. SOX Falls for Sixth Straight Day… Down 4.3% to 11,684 in a Single Session

Investor's Business Daily, 2026-10-14

• The Philadelphia Semiconductor Index plunged 4.3% to close at 11,684.38. That's six straight down days, with a cumulative drop of more than 10%.
• Micron (-4%), AMD (-5%+), Sandisk (-5%+), Intel (-4%), Lam Research (-5%+) and KLA (-3%+) all fell together.
• The Nasdaq closed down 1.88% at 26,692.87 and the S&P 500 fell 1.11% to 7,718.94. The VIX jumped 12.9% to 17.24. AI infrastructure network names CoreWeave (-15%) and Nebius (-10%+) took direct hits.

Chase's take: A six-day losing streak, the first in a year and a half. One stat worth remembering: of the 39 six-day losing streaks since the SOX's 1994 inception, 24 were followed by a higher close on day seven. Maximum fear has historically been close to the bounce zone.

5. KOSPI Falls for Sixth Straight Day… Barely Holds 6,000

NewsPim, 2026-10-14

• The KOSPI closed down 0.44% at 6,008.81, giving back an early 2%+ rally in the afternoon. Six straight down days.
• Foreigners sold for a seventh straight session — ₩1.18 trillion on the day, smaller than the previous session's ₩5 trillion-plus but still concentrated in Samsung and SK Hynix.
• Samsung Electronics closed flat at ₩232,000; SK Hynix fell 1.66% to ₩1,419,000. Both gave back intraday rebounds of 3–4%.

Chase's take: Foreign selling shrank but the direction hasn't changed. With buyback programs finished, the supply-demand gap stays open — rallies will stay weak until foreign buying returns.

6. SEDEX 2026: Samsung vs. SK Hynix Face Off Over PIM

Global Economic, 2026-10-14

• At SEDEX 2026, which opened October 14, Samsung and SK Hynix battled for next-generation memory leadership — both putting processing-in-memory (PIM) front and center.
• Samsung showed working LPDDR-based PIM silicon, alongside HBM4E hardware, zHBM and zNAND-O mock-ups, 2.3D Cube-E and 3D Cube-H packaging, and a CPO model. SK Hynix countered with LPDDR6-PIM, 7th-generation HBM4E and high-bandwidth flash (HBF) — plus an HBM4E wafer personally signed by NVIDIA CEO Jensen Huang.
• In the opening keynote, SK Hynix development chief Ahn Hyun projected AI infrastructure performance will grow 19x by 2030 versus 2026, laying out a roadmap to 3D-stacked DRAM and HBF.

Chase's take: The axis of memory competition is shifting from "capacity and bandwidth" to "compute in memory (PIM)." Both companies' bets on the post-HBM game meet today at the JEDEC standardization table.

7. JEDEC Forum Opens Today (10/15) at COEX… AI Memory Standards on the Table

The Elec, 2026-10-14

• The Korea Semiconductor Industry Association hosts the 2026 JEDEC Forum at COEX on October 15, themed "AI Memory Architectures, Testing, and Ecosystem Readiness."
• Samsung and SK Hynix will present LPDDR-PIM technology and standardization trends; Intel, MediaTek and Synopsys also participate. Advantest will address HBM bump testing challenges, and Keysight will present validation technology for the DDR6/LPDDR6 transition.
• JEDEC is the international standards body for the semiconductor industry — the specs set here decide the shape of the memory market.

Chase's take: JEDEC standards are "market power," not just "technology." Whoever leads LPDDR-PIM standardization decides the on-device AI memory landscape for the next five years.

8. Semtech Reserves Tower Semi Fab Capacity… Price Undisclosed

The Inference, 2026-10-13

• US chipmaker Semtech signed a deal reserving dedicated silicon-germanium capacity at Tower Semiconductor fabs in the US, Israel and Japan. No dollar amount or wafer count was disclosed.
• Semtech shares fell 10.15% to $168.28 on the news — the market read "undisclosed price" as uncertainty, not confidence.
• Semtech holds its analyst day today (10/15), presenting long-term financial targets. Its interconnect chips move data between AI servers.

Chase's take: A "price-undisclosed capacity reservation" is both a statement of demand confidence and an admission of inventory risk. The speed of the 800G → 1.6T → 3.2T transition decides whether this bet pays off.

Frequently Asked Questions

Q1. When does TSMC report, in Korea time? The conference call runs 3:00–4:30 PM KST on October 15 (2:00 AM ET). Q3 revenue of NT$1.49 trillion is already confirmed — watch for gross margin guidance (65–67%) achievement, the N2 ramp and Q4 guidance.

Q2. ASML posted record earnings — why did the stock fall? The market is reacting to valuation and macro, not demand. With September CPI beating expectations and rate-hike fears rising, even great earnings couldn't lift the stock. In "good news can't rally" phases, the price debate dominates the numbers.

Q3. How serious is the SOX's six-day losing streak? It's down more than 10% over six days, the first such streak in a year and a half. But of 39 six-day losing streaks since 1994, 24 bounced on day seven. Maximum fear has historically sat close to the bounce zone.

Q4. What should I watch today (October 15)? TSMC Q3 earnings (3 PM), the JEDEC Forum (COEX), day two of SEDEX 2026, and the Semtech analyst day. By tomorrow morning we'll see how the US market reacted to TSMC's numbers.

Figures and quotes are based on public reports from October 14–15, 2026; intraday figures may change.
