Sandisk shares gained 4.12% to $1323.43 in Wednesday premarket trading as upbeat AI infrastructure demand signals from CoreWeave and Super Micro Computer boosted sentiment across memory and data-storage names. Micron Technology, Western Digital and Seagate also traded higher, reflecting investor expectations that stronger AI data-center spending could translate into firmer demand for storage and memory hardware. The broader market added support, with Nasdaq futures up 0.69% and S&P 500 futures up 0.24%. Technically, Sandisk remains in a longer-term uptrend, trading about 50% above its 200-day simple moving average of $883.31, although its intermediate trend is weaker with the stock 20.7% below the 50-day SMA of $1,671.54 and 3.6% below the 100-day SMA of $1,375.07. Momentum indicators improved, with MACD (moving average convergence divergence) above its signal line and a positive histogram, suggesting selling pressure is easing. Key resistance is $1,446.50 and support is $1,277.50. Sandisk carries a consensus Buy rating with an average price forecast of $2,114.77. Recent analyst actions included an Aug. 10 upgrade to Buy from Argus Research, while RBC Capital Markets kept Sector Perform and raised its target to $1,300 on Aug. 6, and Wells Fargo maintained Equal-Weight while lowering its target to $1,400 the same day. The stock also has sizable weightings in several ETFs, including Invesco S&P 500 Pure Growth ETF, Global X Nasdaq 100 Covered Call ETF and First Trust US Equity Opportunities ETF, meaning fund flows may add to buying or selling pressure.
