If I had to sum up today in one line: the index smiled, but semiconductors cried. Two straight days of cooling inflation — CPI, then PPI — is genuinely good news, but the index gains actually came from mega-caps like Apple, Amazon, and Alphabet, while chips fell roughly 4% on the Micron shock. What stands out most is that Micron delivered a blowout beat (EPS +22% vs. consensus) and still fell 8% — a textbook case of 'good earnings, bad narrative, falling stock.' The volatility in newly listed names (SKHY, SPCX) also deserves continued attention. Double-digit daily swings recurring in week one of trading signal thin liquidity, and it likely takes more time before prices settle.
📊 Top Movers
🧭 Sector Performance
🇰🇷 Korean Investor Perspective
Today was 'rollercoaster day two' for SK Hynix ADR (SKHY) holders — after yesterday's surge, the stock corrected 9%, marking yet another double-digit swing less than a week after listing. Investors holding the domestic shares (000660) should keep in mind that this volatility can transmit to the Korean listing through the mutual-conversion structure. Meanwhile, Nasdaq-tracking ETFs like QQQ likely gained on Apple/Amazon/Alphabet strength, while semiconductor-heavy ETFs like SOXX likely fell on the Micron shock — a reminder that 'US stocks' can mean opposite outcomes depending on which index you track. USD/KRW extended its decline to ₩1,486 (a stronger won), continuing to work against unhedged investors' won-denominated returns.
📊 Market Overview
US stocks closed higher on Wednesday, July 15, as June's Producer Price Index also came in below expectations — a second straight day of cooling-inflation signals. The S&P 500 rose 0.38% to 7,572.40, the Nasdaq Composite gained 0.62% to 26,269.23, and the Dow Jones Industrial Average added 0.29% to 52,658.64. Apple set a fresh all-time high of $327, pushing its market cap toward $5 trillion, while Amazon, Alphabet, and Microsoft all climbed 2-4%.
Beneath the index-level gains, however, was a sharp rotation. Memory-chip bellwether Micron plunged 8% in a single day, dragging Intel, AMD, and Marvell down with it, while SK Hynix's Nasdaq ADR (SKHY) — which had surged the day before — also pulled back on profit-taking. It was a day defined by 'Big Tech up, semiconductors down.'
🔑 Key Issues
1. PPI also undershoots — a second straight day of cooling inflation June's Producer Price Index fell 0.3% month-over-month, below the flat consensus. Core PPI (ex food and energy) rose just 0.2%, also below the 0.3% expected. Coming a day after the CPI surprise, back-to-back soft inflation prints further eased worries about a July rate hike.
2. Apple hits a fresh record — up 20% year-to-date Apple shares hit an all-time high of $327, marking the stock's 15th intraday record of 2026, with market cap nearing $5 trillion. Citigroup raised its target from $315 to $365, citing record 25% smartphone share, continued PC share gains, and pricing power evidenced by a 48-49% gross margin guide maintained even amid a memory-chip shortage.
3. Micron plunges 8% on China competition fears Micron fell 8%, breaking below its $900 support level, after reports that Apple is testing memory chips from China's CXMT (ChangXin Memory Technologies) for devices sold in China. Ironically, Micron's own fiscal Q3 results beat consensus handily — revenue of $41.46B versus $35.69B expected, adjusted EPS of $25.11 versus $20.49 expected — but China-competition fears overwhelmed the earnings beat. The shock spread across the sector: Intel -4.4%, AMD -3.5%, Marvell -7%.
4. SK Hynix ADR (SKHY) pulls back 9% on profit-taking SK Hynix's Nasdaq ADR (SKHY), which had surged the prior day, closed at $176.46 — down roughly 9% from the previous close. Extreme volatility has continued since listing, likely driven by a combination of Micron-triggered memory-competition worries and valuation-driven profit-taking. With double-digit daily swings recurring in its first week of trading, holders of the domestic shares (000660) should note that the ADR's volatility can transmit back to the Korean listing through the mutual-conversion structure.
5. Wall Street split ahead of Netflix earnings Ahead of tomorrow's (7/16) earnings, Morgan Stanley cut its Netflix target from $115 to $90 while maintaining a Buy rating, citing subscriber-churn risk from price hikes, seasonal softness, and a lighter content slate. Yet the same note called engagement worries "largely overblown," seeing second-half live events and sports as a potential rebound catalyst.

🚀 SPCX (SpaceX) Update
SPCX closed at $135.27, dipping below its $150 IPO price for the first time since its June 12 listing. Barely a month after debut, the stock has now fallen through its offer price, as early-investor profit-taking continues amid broader volatility across chips and growth names. No launch- or contract-related negatives were identified for the session.
⚠️ Investor Considerations
Two straight days of soft inflation prints don't guarantee a rate cut is locked in. Micron's episode is also a reminder that a single piece of news — a China-competitor report — can overwhelm even a strong earnings beat from a quality company. The extreme volatility in newly listed names (SKHY, SPCX) also bears continued watching.
