Today's U.S. Stock Market Summary: SK Hynix Listing Ignites Storage Sector, Technicals Remain Bullish

**Overall Market: Broad Gains**
The U.S. stock market saw broad gains, with the S&P 500 rising 0.81%. The Nasdaq was stronger, up 1.3%, breaking above the upper trendline of a triangle consolidation pattern on the daily chart. If it can successfully break out of this range, there is potential for a new leg higher. The Russell 2000, representing small- and mid-cap stocks, performed well, gaining 1.37%. The Dow Jones Industrial Average continued to climb and hit new highs, indicating that traditional mature companies are also rising steadily in this rally.

AI concept stocks and software stocks surged. The IGV tech software ETF rose 2.3%, and the software sector gained about 1.38%. There was clear divergence among mega-caps: Meta rebounded strongly, Tesla and Apple edged up, while Google, Amazon, Nvidia, and Microsoft lagged or fell slightly. In contrast, defensive sectors such as consumer staples, energy, utilities, and healthcare underperformed. When semiconductors rise, defensive sectors fall; when semiconductors fall, defensive sectors play catch-up.

**Meta's Blockbuster Moves: A Complete Reversal in One Day**
Meta released its next-generation code model, MuseSpark 1.1, today, costing only about one-seventeenth of top-tier models like Anthropic. The news was met with strong market enthusiasm, reversing Meta's stock from a 4% intraday decline to a final gain of over 2%. At the same time, Meta is advancing multiple business lines: first, it continues to expand computing power, planning to build a 1-gigawatt-scale data center in Alberta, Canada, indicating that AI computing demand has not become oversupplied as the market feared. Second, in partnership with Broadcom and manufactured by TSMC, it is launching its own custom chip, IISAI, aimed at reducing computing costs and reducing dependence on Nvidia and AMD. Third, it introduced a new model, MSpark, with official API pricing 75% cheaper than comparable models from OpenAI and Anthropic, sparking a price war.

From a valuation perspective, Meta currently has a market cap of $1.6 trillion and a P/E ratio of about 23x, compared to Google's $4.3 trillion market cap and 27x P/E, making Meta's valuation relatively attractive. Broadcom, as a beneficiary of this custom chip chain, will continue to benefit from the demand for custom ASIC chips from various manufacturers.

**SK Hynix Lands on U.S. Stock Market**
The biggest market focus in recent days is undoubtedly SK Hynix's U.S. stock listing. The ADR trades under ticker SKHY, with an IPO price set at $149 (only 3.1% above the closing price in Seoul), a fundraising range of $25.7 billion to $28 billion, and a 7x oversubscription rate.

To secure cheaper shares during the July 9 pricing bookbuilding, institutions had been driving down the stock price in Seoul, causing SK Hynix to plunge as much as 14.6% in a single day and Samsung to fall 9.1%, followed by a V-shaped rebound with a single-day gain of over 8%. This was not a fundamental issue but rather the market using the opportunity to force deleveraging of highly leveraged, overextended positions, combined with institutions deliberately depressing prices before the offering. Once the IPO price was set, institutions rushed to grab shares, resulting in the 7x oversubscription. Samsung's Q2 earnings guidance showed a record operating profit, about 19 times last year's, but the stock fell 7% on the day due to slightly weaker-than-expected revenue. This precisely shows that the decline was sentiment-driven, not fundamental. The shortage of HBM memory chips is expected to last at least until 2028.

However, a reminder on cross-border arbitrage risks is necessary. In theory, if the ADR premium becomes too high, institutions can convert shares purchased in Korea into ADRs via custodian banks to arbitrage the premium on the U.S. market. Ordinary investors should never blindly chase highs at the hottest moment of the opening, and it is even more inadvisable to go all-in. Institutions have tools like automated monitoring, large-scale share conversion, and short selling through borrowed shares; individual investors can hardly participate in this arbitrage effectively.

On the first trading day (July 10), the stock traded under a temporary ticker SKHYW on a "when-issued" basis. It will switch to the official ticker SKHY next Monday (July 13) and settle on the 14th. Sharp volatility at the open and during the session is normal.

Micron Technology announced an immediate $3 billion investment, raising its total U.S. investment plan from $200 billion to over $250 billion by 2035. The news triggered a 9% surge in the stock price. The South Korean government, Samsung, and SK Hynix have also previously announced capacity expansion plans worth hundreds of billions of dollars.

**Macro Focus: Iran Tensions Escalate, SPR Reserves Running Low**
Geopolitical tensions remain high. Trump declared the previous ceasefire agreement over, and the U.S. military conducted airstrikes on about 90 Iranian military and naval targets for two consecutive nights. Iran retaliated by launching missiles at U.S. bases in Kuwait, Bahrain, and a command center in Jordan. Although the Strait of Hormuz has resumed traffic, transit volume has halved. More alarmingly, the U.S. Strategic Petroleum Reserve (SPR) is only 19 million barrels above its estimated minimum operating level, meaning that if a major supply disruption occurs in the Strait of Hormuz, the U.S. safety buffer is nearly exhausted. The market currently prices only about a 33% probability of a U.S.-Iran nuclear deal this year, near historical lows. This geopolitical line is unlikely to cool down significantly in the short term.

Treasury yields retreated after spiking, with the 10-year yield around 4.54%. The Fed's balance sheet reduction (ongoing Treasury holdings reduction) itself pushes bond yields higher, and the market is also pricing in the inflation risk from potential renewed war.

The market has largely become desensitized to this.

**Macroeconomic Data: Labor Market Still Resilient, Housing Data Slightly Cooler**
Initial jobless claims came in slightly below expectations, indicating continued labor market resilience. Existing home sales were slightly below expectations, which helped push Treasury yields lower and bonds stronger, also prompting a rebound in gold and silver prices.

**Market Sentiment Indicators: Extreme Optimism, Almost No Hedging, but High Expected Volatility for Tech**
Several sentiment indicators are noteworthy. The S&P 500 put-call skew has dropped to 0.71, near an all-time low, suggesting investors are paying almost no hedge costs for a potential pullback in the broad market—a relatively dangerous state of extreme optimism. Meanwhile, the ratio of the Nasdaq 100 Volatility Index (VXN) to the S&P 500 Volatility Index (VIX) has risen to 1.7, the highest since 2002, indicating that the market expects tech stocks to experience much sharper swings than the broader market. The AAII Investor Sentiment Survey is neutral, with roughly equal bullish and bearish proportions.

**Technical Analysis: S&P and Nasdaq Bullish, Small-Caps a Concern**
The S&P 500 (SPY) daily momentum has turned positive and is pointing upward, establishing a structure of higher lows. Key resistance tomorrow is around 752-756. Any short-term pullback would be an opportunity to add long positions. However, if the technical structure deteriorates and turns back downward, it would indicate that this bullish attempt has failed, and the market would likely retest lows again.

The Nasdaq 100 (QQQ) has repaired relatively cleanly, recovering from a false breakdown above the wedge. The previous bearish divergence signal has played out. Among the three major indices, QQQ has the clearest and most tradable trend. The expected intraday range is roughly a low of 714 and a high of 732. The ideal scenario would be a healthy pullback first before continuing higher.

The Russell 2000 (IWM) is a different story—it is the most concerning of the three indices. The daily chart shows extremely rare multiple bearish divergences (quadruple RSI, triple MACD), suggesting a potential weekly-level correction. Moreover, IWM is already at a relatively high level, making chasing longs here risky. It is likely to see only a weak bounce without making new highs. Recommendation: Focus on the S&P and Nasdaq; set aside IWM for now.

The VIX is compressed very low and likely to remain in a low range around 15 in the near term. However, there is an important timing to note: This month's VIX options expiration coincides with a potential high point for the market. If the market has rallied significantly by then, there is a risk of a sharp reversal around that time. Be prepared mentally; don't be caught off guard by sudden volatility.

**Summary**
Today's core logic is clear: SK Hynix's listing and Micron's increased investment boosted sentiment in storage and semiconductors. Meta's consecutive blockbuster moves also reignited market imagination for the AI application and custom chip tracks. Overall market technicals remain within a bullish channel.

However, several points require attention: The options market shows almost no hedging for a pullback, tech stock volatility expectations are elevated, geopolitical risks from Iran and the tight SPR remain, and the Russell 2000 (IWM) technicals have issued a rare warning. The overall stance remains constructively bullish, viewing a potential pullback in August-September as an opportunity to buy the dip. The previous view of S&P 500 first to 7800 then 7000-7200 remains unchanged, but it will not be a sharp decline; the topping process is likely a volatile grind lower with lower highs and lower lows, during which individual stocks and sectors will still offer many opportunities. In terms of trading rhythm, pay extra attention to the sharp volatility around the VIX options expiration.
