Financial reports are explosive, yet stock prices plummet.

On August 5 after market close, two major U.S. memory giants—SanDisk and Western Digital—released their earnings simultaneously: ・SanDisk: Q4 revenue of $8.96 billion, up a staggering 372% year-on-year—far exceeding market expectations; approved a $14 billion share buyback. ・Western Digital: Revenue of $3.747 billion, up 44% year-on-year; net profit surged 12-fold—also comprehensively beating expectations. So what happened? SanDisk plunged 7% after hours; Western Digital tumbled 11%. This isn’t the first time. In July, SK Hynix reported its Q2 earnings: operating profit soared 18-fold year-on-year—yet its stock crashed 30% intraday. The better the earnings, the steeper the fall. This is the 'magical realism' of the memory chip sector. Why? Because memory chips are a textbook cyclical industry. Memory chip prices swing like a rollercoaster through distinct cycles: surging when supply falls short of demand—driving massive profits—and collapsing when oversupply hits—triggering losses. A full cycle typically lasts 3–4 years. Cyclical stocks follow a valuation logic diametrically opposed to that of typical growth stocks: Stage Industry Conditions Stock Price Performance Cycle Bottom Industry-wide losses, widespread pessimism Price quietly bottoms out and begins rising Early Upswing Earnings shift from loss to profit Price accelerates upward—largest gains occur here Mid Upswing Earnings sustain high growth and beat expectations Price continues rising—but at a decelerating pace Peak of Prosperity Earnings hit record highs, but growth slows Price peaks and begins falling Early Downturn Earnings still rise—but growth decelerates Price plunges rapidly Late Downturn Industry-wide losses return Price hits bottom—awaiting next cycle The core rule is simple: stock prices always lead earnings by 6–12 months. When earnings are strongest, that’s often precisely when the stock price has peaked. Why? Because savvy investors quietly take profits just as 'everyone is bullish and earnings shine brightest'—they know that after the peak comes the downturn. Where lies the 'crack' in SanDisk’s (and peers’) story? Specifically for this memory cycle, markets are growing concerned about: 1. Slowing price-increase momentum: DRAM contract price growth has shrunk—from over 90% quarter-on-quarter in Q1 to an expected 13%–18% in Q3—signaling a clear inflection point. 2. Weak consumer demand: While AI server demand remains robust, consumer electronics—including smartphones and PCs—have yet to stage a broad-based recovery, casting doubt on the sustainability of a cycle propped up by a single pillar. 3. Supply-side risks: Fueled by high profitability, Samsung and SK Hynix are ramping up expansion plans—potentially increasing future supply. 4. Guidance below expectations: SanDisk’s revenue guidance for next quarter—midpoint $10.55 billion—falls short of the market’s $11.16 billion consensus. This proved the final straw. Once markets sense 'the most profitable phase may already be behind us,' stock prices will drop—even while earnings continue rising. II. Four Core Reasons: Why 'Strong Earnings, Falling Stock Price' Is So Common Memory chips represent the most extreme case—but 'strong earnings, falling stock price' is by no means unique to memory. It has occurred across tech, consumer goods, pharmaceuticals, new energy… virtually every sector. The four underlying reasons, summarized, are:

When policy shifts from blueprint to performance, expectation gaps often pose the greatest risk.

NVIDIA’s financial report was explosive—but the market has learned to vote with its feet. On August 27, 2026, NVIDIA delivered a near-perfect result: Q2 revenue of $96.221 billion, up 106% year-on-year and 18% quarter-on-quarter—setting a new record for the 13th consecutive quarter. Adjusted EPS stood at $2.22, up 120% year-on-year. Data center revenue reached $89 billion—92% of total revenue—and grew 117% year-on-year. Even more surprising: NVIDIA issued revenue guidance one full year ahead—forecasting approximately 70% growth for fiscal year 2028, far surpassing the market’s prior estimate of 45%. Its Q3 revenue guidance of $108 billion (±2%) also exceeded the consensus range of $103–104 billion. Yet, before the earnings release, NVIDIA’s stock had fallen for seven consecutive trading days—the longest such streak in nearly four years. Though it rose over 4% after hours following the announcement, it still closed down 1.59% on Wednesday. Beating expectations has become the default script. Of NVIDIA’s previous six earnings releases, five were followed by next-day stock declines. What the market truly cares about is no longer whether results beat estimates—but whether next-generation tech products can sustain demand for computing power, whether hyperscale customers’ AI monetization is accelerating, and whether AI infrastructure build-out is shifting from 'spare-no-cost GPU acquisition' toward stricter capital discipline. As 'beating expectations' becomes routine, its marginal impact on sentiment is rapidly diminishing. A-Share euphoria: domestic and global forces align—but trading volume raises questions. NVIDIA’s earnings acted like a shot of adrenaline, directly igniting China’s A-share market on August 27. The STAR Market 50 Index surged 3.77%, closing at 1,693.48 points. The Shanghai Composite rose 1.13%, the Shenzhen Component Index gained 1.50%, and the ChiNext Index climbed 1.71%. Over 3,300 A-share stocks advanced. Total turnover across the Shanghai and Shenzhen exchanges reached RMB 2.13 trillion—up RMB 317.2 billion from the prior session. The semiconductor sector rose 4.22%, with main funds net-injecting RMB 18.254 billion; the electronic components sector gained 3.77%, attracting RMB 22.406 billion in net inflows. Memory chips, CPO, PCBs, and optical fiber—key hardware enablers of AI compute—saw wave after wave of涨停 (trading limit-ups). Yet two data points warrant caution: First, heavyweight sectors—including banking, premium liquor, and power equipment—declined against the trend. Second, only around a dozen stocks traded over RMB 10 billion in volume—while leading blue-chips showed divergent performance. This looks more like intra-market fund reallocation into tech—not a large-scale influx of fresh external capital. The market remains in a consolidation-and-bottoming phase, with the 3,900–4,000 point range likely to undergo repeated tests. Macroeconomic alignment: strong headline numbers—but structural divergence intensifies. On the same day, China’s National Bureau of Statistics released data lending macro-level support to the tech rally: January–July national industrial profits totaled RMB 4.58206 trillion, up 17.6% year-on-year. High-tech manufacturing profits surged 50.1% year-on-year—contributing 9.6 percentage points to overall industrial profit growth. The standout performer was the integrated circuit industry—its profits skyrocketed 18.5-fold year-on-year, contributing over 80% to the entire electronics sector’s profit growth. Optical fiber manufacturing profits jumped 468.4%, optical cable manufacturing rose 62.6%, and communications systems equipment manufacturing grew 55.0%.
