Market Overview

Under the triple pressure of rising long-end U.S. Treasury yields, higher oil prices, and Walmart's disappointing earnings report, all three major indices fell on August 20. $Nasdaq Composite Index (.IXIC.US)$ The Nasdaq Composite dropped 1%, $S&P 500 Index (.SPX.US)$ the S&P 500 declined 0.87%, $Dow Jones Industrial Average (.DJI.US)$ and the Dow Jones Industrial Average fell 1.32% (marking its largest single-day point drop in 2026). Meanwhile, the memory storage and optical communication sectors bucked the trend to rebound, $PHLX Semiconductor Index (.SOX.US)$ with the Philadelphia Semiconductor Index rising 0.53%, $Micron Technology (MU.US)$ Micron Technology up 3.97%, $SanDisk (SNDK.US)$ SanDisk up 2.02%, $Marvell Technology (MRVL.US)$ and Marvell Technology up 5.79%. $Applied Optoelectronics (AAOI.US)$ Applied Optoelectronics surged more than 5% intraday.

SanDisk SNDK

Market Recap: $SanDisk (SNDK.US)$ SanDisk has continued to experience significant volatility at high levels over the past two days. On August 19, spurred by news of SK Hynix's share buyback, it opened 3.5% higher but retreated after an intraday peak, briefly breaking below the 1,600 integer support level to hit 1,542 before closing down 3.50%. On August 20, driven by a broader rebound in the memory sector, it rose 2.02%, reclaiming the 1,600 level and closing at $1,600.62, resulting in a cumulative two-day decline of 1.55%. The price action exhibited a wide-range oscillation pattern characterized by "higher open, lower close, followed by a bottom-fishing rebound," with intense battles between bulls and bears near the 1,600 mark.

Fundamentals: The logic behind the AI storage super-cycle remains intact, with backlog orders hitting a record high of $93.9 billion. Revenue for FY26 Q4 is projected to increase by 372% year-over-year. Demand for enterprise SSDs remains robust, and the supply-demand balance for NAND is tight.The breakdown during intraday trading on August 19 was driven more by technical selling pressure than by deteriorating fundamentals; the company's medium-to-long-term investment thesis remains solid.

Technical Analysis: On August 20, the stock reclaimed the 1,600 integer level and formed a MACD golden cross, signaling short-term stabilization. However, upside potential is capped by dual resistance from the 5-day moving average (MA5) at 1,645 and the 60-day moving average (MA60) at 1,660. A reversal can only be confirmed if the rebound is accompanied by heavy volume breakthrough. Support lies at 1,560–1,580, while resistance is at 1,645–1,660.

Price Forecast (1–2 Days): It is highly likely to consolidate within the 1,600–1,660 range. A high-volume breakout above 1,660 would target 1,700, while a drop below 1,560 would see further declines toward 1,500–1,528.

Tesla TSLA

Market Recap: Tesla rose initially before pulling back over the past two days. On August 19, it surged 4.23% on news that the Cybercab would potentially make its debut in Austin as early as late August. On August 20, it corrected 1.71% on lower volume, closing at $345.13, for a cumulative two-day gain of 2.43%. The pullback was accompanied by a noticeable decrease in volume, indicating healthy consolidation after profit-taking on positive news. The volume-price structure remains sound, and the bullish trend has not been broken.

Fundamentals: Q2 revenue increased 26% year-over-year, indicating expansion in its core automotive and energy storage businesses. However, net income fell 5% year-over-year, and free cash flow turned negative, putting pressure on earnings quality. Current valuations largely hinge on three long-term narratives: the commercialization of the Cybercab robotaxi, mass production of the Optimus humanoid robot, and scaling of energy storage and AI energy businesses. If the Cybercab debut in Austin proceeds as scheduled in late August, it will serve as the strongest short-term catalyst; any delay could lead to a disappointment-driven sell-off.

Technical Analysis: Short-term moving averages are in a bullish alignment, but the KDJ indicator has entered overbought territory, and the share price is approaching the upper Bollinger Band at 354, suggesting a need for a technical correction in the short term. Support lies at 330–338, with resistance at 354–355.

Price Forecast (1–2 Days): It is highly likely to oscillate at high levels within the 330–355 range while awaiting official announcements regarding the Cybercab. An official announcement accompanied by a high-volume breakout above 355 would target 365–375, while a drop below 338 would see a retest of 330.
