Old-School Tech Stocks Suddenly Steal the Spotlight

Monday, September 22, 2025


​From AI Darlings to Disk Drives
Forget the glitzy AI giants for a second — the hottest stocks this year aren’t futuristic moonshots, but old-school players making hard drives and memory chips. Seagate is the best performer in the S&P 500, soaring 156%, while Western Digital isn’t far behind with a 137% gain. Micron also surged 93% after a 12-day winning streak.

Bubble Talk or Real Growth?
For bulls, it’s proof that AI infrastructure demand is unstoppable and lifting even the most “boring” tech names. For skeptics, it’s a glaring red flag: when money chases second-tier trades, markets may be in bubble territory. As one strategist put it, this looks like a late-cycle stampede.

Big Tech Still Spending Big
Behind the surge is relentless spending by giants like Microsoft and Alphabet, pouring billions into semiconductors, storage, and electricity to fuel data centers. Nvidia and TSMC have already hit trillion-dollar valuations, but now even overlooked firms like Seagate and Western Digital are cashing in on the AI arms race.

The Snooze-Worthy Heroes
These companies may not scream excitement — after all, hard drives debuted in the 1950s — but their products are suddenly critical. Training massive AI models requires oceans of data, making memory chips and storage the unsung heroes of the boom.

Hype Meets Reality
Not everyone’s convinced. Some fund managers warn that AI is overhyped, like the early internet, and its real-world applications will take longer than markets expect. Still, chipmakers, storage firms, and even power producers like Vistra are enjoying wild rallies as AI keeps sucking up infrastructure dollars.

Valuations Rising Fast
Despite their old-school vibes, these stocks aren’t cheap anymore. Seagate now trades at 20 times earnings, up from just 10 earlier this year. Analysts see room for more upside — one recently set a $250 price target, above its current $221 — but warn the pace is stretching forecasts.

Time to Cash Out?
​With prices outrunning Wall Street’s targets, some pros suggest locking in profits. History shows cyclical tech stocks peak when valuations look healthiest — and that might be exactly where we are now.
