Google's TurboQuant data-compression technology triggered a semiconductor sector selloff based on the misconception that efficiency gains would reduce hardware demand. However, analysts argue this represents a classic market overreaction. Efficiency improvements historically create virtuous cycles of innovation, enabling larger and more complex AI models that actually require more powerful memory and storage. Companies like Micron, Western Digital, and Applied Materials remain well-positioned to benefit from accelerating AI infrastructure buildout, with their 2026 demand already sold out or fundamentally sound.

Three stocks—Opendoor Technologies, Newegg Commerce, and Sandisk—have delivered exceptional returns of over 350% in the past year following the April 2025 tariff announcement. A $10,000 investment in each would now be worth approximately $263,000. However, while Sandisk shows strong fundamentals with 42% revenue growth, Opendoor and Newegg are characterized as risky meme stocks with weak financials and significant downside risk.

REalloys is building the only non-Chinese supply chain for rare earth magnets, critical components in defense systems, medical devices, and consumer electronics. With a January 2027 Pentagon deadline requiring defense contractors to eliminate Chinese-sourced rare earths and global demand expected to triple by 2035, REalloys' exclusive offtake agreement and Ohio processing facility position it as a key player in a $20-30 billion market. The company's Saskatchewan facility is expected to reach full production in 2027, with Phase 2 expansion targeting 20,000 tonnes annually of heavy rare earth permanent magnets.

Western Digital is leading scalable rare earth recovery from end-of-life hard drives through successful pilot programs and partnerships, positioning itself as a key node in establishing a domestic feedstock network for the U.S. supply chain.
Micron Technology stock plummeted 9.60% on March 30, 2026, as investors shifted focus from record AI-driven growth to concerns that Google's new TurboQuant algorithm could reduce memory demand by compressing memory requirements up to six times. The broader market saw the S&P 500 slip 0.39% and Nasdaq Composite lose 0.73%, with semiconductor peers Sandisk and Western Digital also declining significantly.

AI Insight
Stock dropped 8.60% alongside other semiconductor memory peers due to investor concerns about reduced memory demand from more efficient AI algorithms.
While the S&P 500 has fallen 4.5% since a Middle East war began, three sectors remain resilient: energy stocks are surging due to spiked oil and gas prices; computer hardware and data storage companies continue benefiting from strong AI infrastructure demand; and cybersecurity firms are gaining as geopolitical tensions drive demand for security products.

Up 11% in March and 78% year-to-date, benefiting from surging AI-driven demand for data storage products
While the broader market has pulled back from all-time highs in 2026, Palantir Technologies and Sandisk continue to trade near their peaks. Palantir benefits from surging demand for its AI Platform in the commercial sector, though its valuation is expensive at 51x forward P/S. Sandisk is riding high on soaring NAND flash memory prices driven by AI infrastructure demand, trading at a cheap 8x forward P/E but remains speculative.

SanDisk stock has surged over 1,200% in the past year following its spinoff from Western Digital, driven by strong demand for memory and storage products. While some analysts have bullish price targets exceeding $800, the consensus target of $570 suggests potential downside of 23%. The author recommends caution, noting that high expectations are already priced into the stock and any slowdown in demand could be risky.

Federal Reserve Chair Jerome Powell warned that the escalating Middle East conflict will push U.S. inflation higher in the near term, though he ruled out stagflation and described the economy as resilient. The Fed held rates unchanged at 3.50%-3.75%. Powell noted that while higher oil prices would boost domestic drilling and corporate profits, there would still be downward pressure on spending and employment. Markets reacted negatively, with equities falling and several large-cap stocks declining significantly.

Dropped 2.83% as technology sector faced headwinds from rising yields and economic uncertainty
Sandisk stock has surged 1,200% in the past year, driven by exceptional earnings growth fueled by acute shortage of flash storage and enterprise SSDs demanded by AI data centers. With current market cap of $105 billion, the company would need a 10x jump to reach $1 trillion valuation. While analysts project potential 5x growth based on expected $86.02 EPS and tech sector multiples, this may not be sufficient for trillion-dollar status, though the rally appears sustainable given supply constraints expected through 2028.
The Motley Fool•Harsh Chauhan
AI Insight
Company benefits from the same supply shortage dynamics as Sandisk, with firm purchase orders for HDD shipments extending through 2027-2028. The article mentions Western Digital as a beneficiary of strong AI data center demand for storage products.
