SanDisk has a long way to fall because it is a budget SSD maker trading at a P/E of 36. The leveraged SanDisk fund is already down 89%. x.com

Sandisk lacks a real moat now that China has replicated high-performance NAND, unlike Micron's slight edge in HBM, which could spell trouble for it versus Micron. Apple has switched to Chinese suppliers for its international products, though Sandisk may have some special data-center advantage. x.com
Micron's cheaper forward valuation, stronger revenue growth and higher five-year ROIC make it the better buy than Sandisk, alongside its exposure to AI-driven HBM demand. Per StockAnalysis, Micron's revenue growth is 256% versus 175%, forward P/E is 5.12 versus 5.84, and five-year ROIC is 27.24% versus 21.47%. Sandisk leads on projected EPS growth, at 23.96% versus Micron's 17.16%. x.com x.com x.com
SanDisk has run up about 3,000% since its 2025 IPO, turning a $10,000 investment into nearly $300,000 in a year. x.com
Sandisk's earnings growth makes its valuation look unusually low, with guidance showing no slowdown. Revenue rose 378% year over year, and $52.5 GAAP EPS implies a 6.1 annualized P/E, below Micron's. Sandisk's roughly 85% gross margin also compares favorably with SK hynix's apparently sub-50% NAND margin. Next-quarter guidance calls for $12.2 billion-$12.6 billion of revenue and $55-$57 non-GAAP EPS. x.com x.com x.com
SanDisk's share price has run beyond the reach of most investors. With no circuit breaker in place, the rally looks like a retail trap, with momentum chasers buying near $1,500 likely to get hurt. x.com x.com
Sandisk looks risky at these levels because China's YMTC is stabilizing cutting-edge NAND yields and ramping production, a predictable threat not yet priced into the stock. Per @jukan05, YMTC plans to mass-produce its most advanced NAND at Wuhan Fab 3 from H2 2026, is winning major overseas customers, and is projected to surpass SK Hynix and Micron in NAND output by year-end. x.com x.com
The need for more memory evident in every company's earnings report makes the market's negative view of Sandisk hard to understand. Yet splitting a stock above $1,000 is one of the dumbest moves a company can make: it hands market makers the ability to manipulate the shares through options, a risk for Sandisk. x.com x.com
Sandisk's growth is coming entirely from higher prices, not more bits shipped, which makes it hard to sustain. Revenue grew 97% quarter over quarter as almost every hyperscaler raised capex to cover rising prices. Its roughly 80% gross margin is excessive and customers resent it; as long as demand far exceeds supply it can keep both, but supply eventually catches up and margins will erode. The open questions are how long new fabs take and whether Sandisk or rivals add the supply. x.com x.com … Show more
Samsung Electronics is ridiculously undervalued given that it sells more NAND than SanDisk and Kioxia combined. NAND alone is worth about half its market cap, so adding its DDR business makes it a much cheaper company on a lower multiple. @insane_analyst notes it is the only one of its peers with an internal logic foundry, logic design group, silicon photonics node and CPO group. x.com x.com
Rising memory contract prices strengthen the case for memory stocks still far below their highs. JPMorgan forecasts Q4 DRAM prices up 13% and NAND up 18%; Micron is 28% below its 52-week high, Seagate 44%, Sandisk 47% and Western Digital 55%. x.com
SanDisk has likely topped for this cycle, and memory stocks such as Micron are rolling over even though fundamentals still look incredible. In cycles, price weakens first, estimates and targets fall later, and the narrative flips only after the damage is done, with vicious failed rallies along the way. SanDisk already guided lower, its gross margin has plateaued and price action has been terrible, so it likely goes lower. Sell on technicals rather than waiting for fundamentals to erode. x.com … Show more
