NEW YORK — Shares of Elon Musk’s aerospace giant, SpaceX, slipped below their debut-day closing price on Wednesday, raising fresh concerns among retail investors, particularly South Korean investors colloquially known as "Seohak Gaemi," who aggressively purchased the stock immediately following its historic public listing last month.

On July 8 (local time), SpaceX concluded trading on the New York market at $148.30 per share, marking a 0.78% decrease from the previous trading day. This drop officially broke through the $150 threshold—the precise level where the stock settled on its high-profile first day of trading on June 12. The descent highlights a sharp reversal for the company, whose shares briefly surged to an all-time high of $201.80 shortly after going public amid massive market enthusiasm.

Despite the recent downward momentum, market analysts point out that SpaceX is still trading above its initial public offering (IPO) price of $135. The stock's correction coincides with a broader pullback in Elon Musk's corporate empire, with electric vehicle manufacturer Tesla also sliding by 2.19% during the same trading session.

The slide comes at a particularly surprising time, just one day after SpaceX was officially integrated into the prestigious Nasdaq 100 Index. Under normal circumstances, inclusion in major benchmarks triggers a wave of programmatic buying, as passive index funds and exchange-traded funds (ETFs) rebalance their portfolios to match the new index composition. However, institutional accumulation was not enough to offset the selling pressure; on its very first day of index inclusion, SpaceX stock cratered by 6.8%, signaling that short-term valuation anxieties are currently overshadowing structural passive inflows.

Market experts maintain that while SpaceX commands an unparalleled, monopolistic position within the global aerospace and artificial intelligence infrastructure sectors—guaranteeing immense long-term growth potential—its near-term stock trajectory remains highly vulnerable to volatility due to stretched valuation multiples.

Meanwhile, the broader New York stock market finished the day with mixed results as geopolitical anxieties resurfaced. Renewed tensions between the United States and Iran weighed heavily on investor sentiment, preventing a coordinated market-wide rally and leaving the three major indexes fragmented.

The Dow Jones Industrial Average shed 576.76 points (1.09%) to close at 52,348.39, while the S&P 500 Index finished at 7,482.71, down 21.14 points (0.28%).

Conversely, the tech-heavy Nasdaq Composite managed to stave off losses and secure a modest gain, climbing 51.96 points (0.20%) to close at 25,870.65. The index was primarily rescued by a series of positive corporate developments among mega-cap semiconductor giants. Broadcom led the tech advance, surging 4.8% following news that Apple Inc. expanded its semiconductor supply agreement with the firm in a massive $30 billion deal. Similarly, AI bellwether Nvidia climbed 3.7% following reports that Chinese regulatory authorities will permit domestic AI firms to purchase Nvidia's specialized H200 chips under a restricted framework.

Other semiconductor players rode the coattails of this momentum. Micron Technology edged up by 1.11%, while SanDisk witnessed a robust 6.77% rally. These collective gains propelled the Philadelphia Semiconductor Index up by 2.2% by the closing bell.

This strong recovery in global chip stocks is expected to have immediate ripple effects in Asian markets. Financial analysts in Seoul are closely watching the Korea Composite Stock Price Index (KOSPI) today, anticipating a potential rebound for domestic technology titans Samsung Electronics and SK Hynix, which typically trade in lockstep with Wall Street's semiconductor sector.
