October 31 Market Report: Intel's 29% Crash Consumed the Trading Day
Intel's 29% plunge swallowed the entire trading day.
According to Yonhap News, the Dow Jones Industrial Average fell 572.25 points (1.09%) to close at 51,770.31, and the S&P 500 dropped 140.32 points (1.82%) to 7,580.07 on the New York market on the 30th (local time). The Nasdaq tumbled nearly 2.9%, posting its worst monthly performance since March of last year. After Alphabet, Amazon and Intel's earnings fell short of expectations one after another, rekindling anxieties over artificial intelligence (AI) investment. As the Greek historian Herodotus' maxim goes—great opportunities come out of crises—and winners and losers diverged sharply among individual stocks amid the sell-off.

As the table shows, while semiconductor and AI hardware stocks were under pressure, the pharmaceutical, consumer and energy sectors finished higher instead. Eli Lilly led the rally with a gain of 0.07%, while Johnson & Johnson (+0.02%), Costco (+0.01%), Chevron (+0.01%) and Exxon Mobil (+0.01%) also held firm in a defensive trend. Notably, a rise of over 2% in international oil prices provided a tailwind for energy stocks.
Key Analysis: What the 'Intel Shock' Shook
The epicenter of this decline was Intel. According to Yonhap Infomax, Intel plunged 29.83% in a single day, marking its worst day in 50 years. The earnings themselves beat market forecasts, but investors' attention lay elsewhere: cash flow and the likelihood of a return on AI-related investments. Behind the stock's more than 20% collapse despite the earnings surprise lies the fact that investment sentiment toward AI hardware as a whole has already grown thin.
The shock spread across the entire semiconductor sector. The Philadelphia Semiconductor Index plunged 7.20%, and AMD fell 10.88%. SK Hynix's ADRs also dropped 7.95%. NVIDIA closed down 4.14% at $204.81, ceding its position as the world's most valuable company to Apple. Based on the closing prices, the gap between NVIDIA at $5.16 trillion and Apple at $5.09 trillion stands at roughly $70 billion, putting the two companies' battle for the crown back into a neck-and-neck race.
The Valuation Crossroads
After the crash, the valuation landscape has become even clearer. Alphabet trades at a P/E of 14.8, Micron at 12.6, and Berkshire Hathaway (Class B) at 13.6—the lowest tier among large-cap stocks. By contrast, Tesla's P/E of 443.2 combined with EPS growth of -4,709.0% confirms its earnings-based instability. Meta, too, saw EPS fall -256.0%, entering a phase where the reliability of its seemingly low P/E of 21.3 is being put to the test.
Looking at the flip side of AI beneficiaries, stocks that posted explosive earnings growth—such as NVIDIA (6,599.3%), Alphabet (3,419.4%) and TSMC (4,354.4%)—still maintain valuations in the 15-28x range. While there is no guarantee that such growth rates will continue, the contrast between companies whose profits grew ahead of their stock prices and those whose stock prices ran ahead of their profits will serve as a key criterion for investment decisions going forward.
Outlook: Cash Flow Is the Deciding Battleground
In the short term, volatility in the semiconductor sector is expected to widen. Even if the analysis holds, a psychological recovery will take time unless the catalyst the market wants emerges. On the other hand, this correction could serve as an opportunity for a re-rating of AI-related stocks with lighter valuation burdens, such as Alphabet and Micron, which trade at P/Es of around 15.
The key to turning crisis into opportunity ultimately lies in the numbers. The cash flow each company demonstrates in next quarter's earnings and the actual conversion of AI investments into profits will determine the direction of the market. As Tom Hanks put it, whether the opportunity is great precisely because it is hard—the data will deliver the verdict.
