Seagate Surges to Record High on 52.87% Jump in Daily Trading Volume as AI Storage Demand and HAMR Innovation Fuel Growth

Seagate Technology (STX) surged 4.34% on Thursday, with a trading volume of $1.01 billion, marking a 52.87% increase from the previous day. The stock climbed to an all-time high of $173.49, driven by surging demand for high-capacity storage in AI applications and advancements in heat-assisted magnetic recording (HAMR) technology.

Analysts highlighted Seagate’s strategic focus on HAMR innovation as a key growth driver. The company’s revenue rose 38.86% year-to-date, with cloud computing and nearline drive demand pushing June-quarter revenue up 36.29%. Nearline drives remain fully booked through mid-2026, underscoring long-term demand in data storage sectors. Institutional upgrades, including Benchmark’s $165 price target and TD Cowen’s $175 target, reinforced investor confidence in Seagate’s market position.

Seagate’s financial resilience is reflected in a “GREAT” health rating, a current ratio of 1.38, and a record 37.9% gross margin in Q4 2025. The firm’s 15-year consecutive dividend streak further signals stable capital returns. However, analysts caution that rising tax rates and potential HAMR adoption delays could temper growth, though Seagate’s emphasis on high-margin, high-capacity drives positions it to capitalize on AI storage expansion.

Backtest results for Seagate’s stock over recent months show consistent alignment with sector trends, particularly in AI-driven storage demand. The company’s disciplined capital allocation and technological edge in HAMR have historically outperformed cyclical downturns, validating its current momentum amid favorable macroeconomic conditions.
