SanDisk Shares Rise 3% as $620M Volume Dips 39% to 144th in Market Activity
Sandisk (SNDK) closed 3.00% higher on Sept. 26, 2025, with a trading volume of $620 million, marking a 39.26% decline from the previous day’s volume and ranking 144th in overall market activity. The stock’s performance followed reports of renewed supply chain adjustments in the NAND flash sector, which analysts noted could stabilize pricing dynamics amid ongoing inventory rebalancing. Recent industry data highlighted growing demand for high-capacity storage solutions in AI infrastructure and cloud computing segments, areas where SandiskSNDK-- maintains a competitive edge in enterprise-grade SSDs.
Market participants observed that Sandisk’s recent partnership with a major hyperscaler to expand data center storage capacity had not yet translated into immediate revenue visibility. However, the company’s Q3 guidance, which emphasized cost optimization and yield improvements, was seen as a positive catalyst for near-term margins. Short-term technical indicators suggested continued consolidation above key support levels, though mixed sentiment lingered over macroeconomic risks to enterprise IT spending cycles.
To run this back-test precisely I need to pin down a few practical details that aren’t fully specified yet: 1) Market universe—should I use all U.S. listed common stocks (NYSE + NASDAQ + NYSE Arca) or another region/universe? 2) Weighting & capital allocation—should the 500 selected names each be held with equal dollar weight (i.e., 0.2% of equity per name) and the portfolio fully invested every day? 3) Re-investment of proceeds—confirm that each day we (a) sell yesterday’s basket at that day’s close and (b) immediately reinvest all proceeds into today’s new top-500 basket, so the strategy remains 100% long at all times. 4) Transaction cost assumptions (commission & slippage)—if none are provided I will default to 0 bp (idealized). 5) Benchmark (optional)—would you like the results compared with a benchmark such as SPY? Once I have these points confirmed I can fetch the required data, generate the daily baskets and run the back-test from 2022-01-03 (first trading day of 2022) through today.
