Seagate Technology’s (STX) explosive 5.83% intraday surge has ignited market chatter, fueled by a $2.59 EPS beat and Mizuho’s $155 price target upgrade. The stock’s trajectory to $157.45—a 56.7% YTD gain—highlights its role as a cornerstone in the AI storage revolution. With cloud demand and HAMR innovation driving momentum, the question is whether this is a sustainable rally or a correction setup.

Mizuho Upgrade and Earnings Outperform Drive STX’s Surge
Seagate’s 5.83% rally was catalyzed by Mizuho’s price target hike to $155 and its reaffirmed 'Outperform' rating, reflecting confidence in the company’s Q2 results. The firm reported $2.59 EPS (beating estimates of $2.45) and $2.44B revenue (surpassing $2.40B forecasts), driven by 29.5% YoY growth. Mizuho also raised 2026–2027 forecasts, citing HAMR technology’s margin expansion and cloud demand. Additionally, the $5B buyback plan signaled management’s belief in undervaluation, further bolstering investor sentiment.

Storage Sector Rally Intensifies as Western Digital Surges 9.63%
Seagate’s 5.83% gain aligns with a broader storage sector upswing, led by Western Digital (WDC)’s 9.63% intraday surge. Both stocks benefit from AI-driven cloud demand and HAMR adoption, but Seagate’s 33.79% gross margin and $8.54B trailing revenue outpace WDC’s metrics. The sector’s momentum is underpinned by long-term data storage tailwinds, with Seagate’s cutting-edge HAMR positioning it as a key beneficiary.
