#股票交易分享挑战 Profits surged 12-fold, yet the stock price plunged 13%—why did the “perfect earnings report” from a U.S. storage giant become a death knell for the capital market?
On August 6, 2026, local time, the U.S. stock market gave every investor who believed that “performance is king” a harsh lesson. On that very day, the global storage giants had just delivered earnings reports that could be called “epic”: Western Digital’s net profit surged 12-fold year over year, SanDisk’s revenue soared 372% year over year, and its gross margin climbed above 80%, reaching a historic extreme. If you looked only at these figures, they clearly appeared to be money-printing machines running at full speed. Yet the capital market’s reaction was extremely cold. Western Digital’s stock price plunged more than 13%, SanDisk fell nearly 7%, and a host of giants including SK Hynix collectively tumbled. Panic even crossed the Pacific, triggering a chain reaction in Asia-Pacific markets. On one side was an industry celebration of “demand outstripping supply and record profits”; on the other was a brutal secondary-market “vote with their feet,” marked by a stampede for the exits.
What underlying logic lies behind this intensely dramatic split?
01. “Flawless” Expectations
Many ordinary investors were completely confused: If AI demand is so strong and major manufacturers’ profits are so high, why couldn’t their stock prices hold up? The answer lies in a vast gap between industrial reality and the capital market. Under Wall Street’s rules of the game, when an industry’s gross margin is pushed above the absolute extreme of 80%, the market no longer values it as a “cyclical stock,” but prices it as a “perfect asset.” For SanDisk, whose gains this year have already exceeded 400%, and Western Digital, which has risen nearly 200%, the positive news from the past several quarters had long since been fully priced in by investors. At that point, merely being “good” was not enough; it had to be “better than expected” to sustain the stock price. When SanDisk provided revenue guidance of $10.3 billion to $10.8 billion for the next quarter, and when the slope of Western Digital’s gross-margin growth began to flatten, even a slight hint of “conservatism” immediately became the perfect excuse for investors to take profits.
The subtext among Wall Street traders was blunt: The day earnings are delivered is the day the good news runs out. When everyone is crowded onto the same boat, any signal of marginal slowing will trigger a stampede of retreat among the bulls.
02. Musk’s “Industrial Truth”
As the market was engulfed in anguish, Musk made a rare statement during SpaceX’s earnings call. He said bluntly that storage had become the most critical bottleneck in the AI industry, with supply growing only 20% annually while demand was increasing by as much as 200% or more. As the head of Tesla and SpaceX, Musk is positioned on the procurement side of the AI industry’s upstream chain. What he sees is the physical world as it truly is: AI servers consume several times more DRAM and HBM than traditional models, cloud providers are competing for capacity at any cost, and high-end capacity has long been locked up by long-term supply contracts. From an industrial perspective, his assessment is entirely sound. But the capital market considers far more than the current boom.
Wall Street elites are worrying about two hidden risks:
First, the “two extremes” on the consumer side. Demand for AI servers is booming, but the recovery of consumer electronics terminals such as smartphones and PCs remains weak. When large amounts of capacity are directed toward high-margin server chips, once the pace of AI capital-expenditure expansion slows, the consumer market alone will struggle to absorb the enormous capacity now in place.
Second, the “reverse surge in costs” under Moore’s Law. As DRAM advances toward high-end products such as HBM4, complex 3D packaging and stringent yield requirements are causing the cost curve for advanced memory to turn sharply upward. Future price increases will no longer be driven purely by a supply-demand mismatch, but supported by a permanently higher physical cost structure. How long can this kind of “passive price increase” sustain extraordinary profits?
03. The Fate of Cyclical Stocks
The massive storage sell-off that took place in the summer of 2026 delivered a vivid lesson in philosophy. From an industry perspective, there is indeed a supply-demand imbalance in memory chips, and the incremental demand brought by AI is real. But the stock market trades on expectations about the future. When valuations get too far ahead of reality, the logic that supply and demand determine prices over the medium and long term must give way to the risk of a reversal in expectations. We cannot crudely equate the industrial insights of leading figures with inevitable stock-market gains. Even industries where demand exceeds supply can experience sharp stock-price corrections. Dividends do not move upward in a straight line; they inevitably include repeated volatility and shakeouts.
For ordinary investors, understanding this logic is crucial. Do not be misled by headlines about “profits surging,” but neither should you completely dismiss the long-term trend in AI computing power because of a short-term plunge. In this uncertain market, the true moat is neither blindly chasing prices higher nor panic selling, but maintaining clarity amid extreme prosperity and discerning common sense throughout the cycle. After all, in the capital market, those who survive are always the ones who remain humble before expectations.
