Top 20 U.S. stock trading volumes on August 14: Sandisk rose 13.67%, and the storage sector strengthened simultaneously

On Thursday, Micron Technology, the top stock by trading volume in the U.S. market, rose 4.23%, with a trading volume of $34.612 billion.

Strong positive signals from core artificial intelligence infrastructure partners have become an important catalyst for Micron Technology. The robust revenue forecasts and expanding backlog orders announced by major AI server manufacturers highlight the continued high spending by enterprises on data center computing hardware. The next-generation AI server platforms require a significant amount of dedicated high-bandwidth memory and advanced DRAM, and the optimistic server deployment guidance has directly boosted investor confidence in Micron as a key storage supplier.

The deeper reason supporting the stock's upward momentum is the structural supply-demand imbalance in the global storage industry. Recent statements from management at industry technology conferences further confirm that the growth rate of AI-driven storage hardware demand is outpacing the expansion rate of manufacturing capacity. The shift towards producing high-bandwidth memory for AI acceleration has significantly reduced the output of traditional storage chips, further tightening overall market supply. Company executives pointed out that the data center storage shortage is expected to last at least until 2027, providing Micron with strong pricing power and long-term revenue visibility through clear long-term commitments from customers.

SanDisk, in second place, rose 13.67%, with a trading volume of $32.618 billion.

On Thursday, SanDisk announced its long-term financial model at the 2026 Investor Day, outlining a series of financial targets to be achieved from fiscal year 2028 to fiscal year 2030, including maintaining mid-to-high double-digit revenue growth during this period. SanDisk also clarified market concerns about bit growth, stating that the available bit supply will be adjusted based on profitability optimization needs, while committing to returning 100% of remaining cash to shareholders after completing business investments.

Following the announcement, the market quickly voted with its stock price. SanDisk (SNDK) saw its intraday gains expand to 17.6% on Thursday; the storage sector also strengthened. By the close, SanDisk had risen nearly 14%.

NVIDIA, in fifth place, rose 0.54%, with a trading volume of $22.135 billion.
