Seagate Technology (STX) fell 9.48% to $772.12 on Thursday amid a broader selloff in storage and memory stocks. The decline followed a sharp intraday drop after an initial 1.2% gap up, as the stock hit a session low of $771.00. The move appears linked to broader market sentiment and comparisons with peer Western Digital, which also slid despite beating Q2 earnings.

What Happened

Seagate opened at $863.11, reflecting a modest gap up from the previous close, but quickly reversed course. The stock peaked at $881.00 shortly after the open before declining sharply, reaching a session low of $771.00 by 10:00 AM ET. The decline coincided with a broader sell-off in the storage sector, as Western Digital fell 16% and SanDisk dropped 11%. Analysts highlighted Seagate’s recent results in their coverage, which may have contributed to investor caution. Additionally, recent insider sales by the CEO and other executives were disclosed, adding to the bearish tone.

What The Data Shows

The stock has traded between $144.75 and $1145.00 over the past 52 weeks. It currently trades at a P/E of 61.4 and has a beta of 2.10, indicating high volatility. Over the last eight sessions, the stock rose 16.1% from $747.30 to $867.36. However, Thursday’s volume of 0.7 million shares was just 0.2 times the 3-month average, suggesting limited participation. Recent insider transactions show 22 sales totaling $127.2 million in the last 90 days, with no insider purchases recorded. Congressional trades include recent sales by Donald J. Trump, though no direct connection to Seagate was made.

What To Watch

Seagate has no scheduled earnings report in the provided data. Investors may monitor the breadth of coverage and any follow-up analysis from analysts who highlighted Seagate’s performance in relation to Western Digital.
