Seagate Technology Holdings PLC

TradingKey - On September 14, memory sector stocks in the US market broadly weakened in pre-market trading. Micron Technology (MU) and SanDisk (SNDK) both fell more than 5%, SK Hynix (SKHY) dropped over 7%, and Western Digital (WDC) and Seagate Technology (STX) declined by over 4%.

TradingKey - STX closed near $904 after a 6.5% surge as HAMR adoption and cloud demand strengthen. Can $926 unlock $962-$1,013?

TradingKey - U.S. stocks generally weakened last Friday as strong non-farm payroll data heightened Fed rate hike expectations, sending the S&P 500 down 0.4% and the Nasdaq down 0.3%. However, the memory chip sector bucked the trend to become one of the market's strongest areas. The Roundhill Memory ETF surged 6.61%, while SanDisk (SNDK) jumped 11.90% to $1,740, becoming the best-performing stock in the S&P 500 that day. Micron (MU), Western Digital (WDC), and Seagate Technology (STX) all recorded gains of around 6%.

TradingKey - As artificial intelligence drives the rapid growth of global data volumes, storage chips and data center hard drives have become an indispensable component of AI infrastructure. While both SanDisk (SNDK) and Seagate Technology (STX) are major players in the storage industry, they differ in their target market segments, business models, and investment theses.

TradingKey - The expansion of AI computing power is driving up data center storage demand. Although HDDs receive less attention in AI storage discussions than high-performance storage media like HBM and NAND flash, they handle the long-term storage of AI training data, inference logs, and model versions.

TradingKey - As of Thursday (August 6) ET, futures for the three major US stock indices showed mixed performance in pre-market trading. Dow and S&P 500 futures edged higher, while Nasdaq 100 futures remained under pressure as the market continued to digest pullback pressures following AI capital expenditures, chip stock valuations, and earnings reports in the memory sector. Investors are also awaiting data on initial jobless claims, Q2 non-farm productivity, and unit labor costs to assess the latest shifts in US employment and inflationary pressures.

Micron led the decline in memory chip stocks, which may continue to face downward pressure.

TradingKey - After the market close on July 28, ET, global hard drive leader Seagate Technology (STX) announced its fiscal fourth-quarter 2026 results. Not only did revenue and earnings for the quarter exceed Wall Street expectations across the board, but the performance guidance for the next fiscal quarter was also significantly higher than market forecasts. Seagate shares fell 8.5% in regular trading prior to the earnings release but rebounded by more than 10% in after-hours trading.

Micron continued to surge to a record high today, poised to break through the $1,200 mark ahead of its earnings release.

TradingKey - Since the start of 2026, the Philadelphia Semiconductor Index (SOX) has surged by nearly 90%, with memory chips serving as the primary driving force. Against the backdrop of the index's upward trajectory, the market capitalizations of the DRAM "Big Three" have successively surpassed the $1 trillion mark. Meanwhile, two individual stocks in the NAND sector have surged over 45-fold over the past year, and hard disk drive (HDD) manufacturers have also undergone a valuation re-rating driven by AI data storage demand. So, which has been the strongest performer in this AI memory supercycle?
