STEM Soars 23% – Hot Stock Today & Top Gainer (July 22, 2025)

Look out – Stem, Inc. (STEM) just exploded as the top gainer stock of today’s U.S. session! The energy-storage tech player rocketed +23.3% in one day, closing around $16.64/share. That surge crowns STEM as one of the hot stock today favorites – it nearly doubled traders’ money in a week (up ~90% in the past 5 trading days. Volume was off the charts too, with over 4 million shares changing hands (way above normal).
For context, STEM recently underwent a 1-for-20 reverse stock split to regain NYSE compliance, shrinking its float to ~8 million shares. Now after this rally, its market cap is still only about $138 million(a tiny micro-cap), so volatility is extreme. Interestingly, there was no big new announcement or earnings release today – this move seems fueled by momentum and trader enthusiasm.
So why STEM stock is up so much? A few likely reasons:
What’s Fueling the Surge?
Retail Frenzy & FOMO: STEM became a hot stock today on social media, with traders on forums jumping in. The massive volume spike shows heavy retail buying and likely some Fear of Missing Out as the price kept climbing.
Short Squeeze Fire: With ~20% of its float sold short, STEM was primed for a squeeze. As the stock took off, short sellers scrambled to cover, which only pushed the price higher in a classic squeeze scenario.
Turnaround Optimism: Fundamentally, some bulls are excited that Stem is pivoting toward higher-margin software services and cutting costs, aiming to improve its finances. After brutal losses last year, any hint of stabilization (new CFO, debt reduction, etc.) has revived confidence that this beaten-down stock could stage a comeback.
Now let’s hear from you:
Is STEM a legit turnaround story or just a meme-style spike that will fizzle out?
Can this top gainer keep climbing, or do you expect a pullback after such a fast move?
Would you buy STEM at ~$16, or is it too risky at this point?
