— Why it moved
Why PLSM Stock Nearly Quadrupled Today — June 24, 2026
Ouma Health picked Pulsenmore's home ultrasound for its maternity telehealth platform, and a 1.5M-share float did the rest — then the stock spent the whole session giving it back.
## What moved it Ouma Health, the largest maternity telemedicine provider in the US, selected Pulsenmore's FDA-authorized home ultrasound for its virtual prenatal care platform. A real partnership, but no financial terms were disclosed.
## The mechanics The float is about 1.5 million shares on a $22M cap. When news hits something that small, price discovery breaks. It gapped 227% overnight and traded roughly 1,800 times its normal volume.
## Numbers - Cap: ~$22M / float: 1.5M - Day volume: 57.6M (~1,800x avg) - Prev close: $3.41 → gap +227% - 52w range: $3.00–$10.28
## Where it ended up Stock Pulse flagged it at 7:19 AM premarket, $11.27, after the stock had already more than tripled. Thin premarket prints touched $19.52 minutes later, but no size traded there. Where real volume showed up, the high was $12.97 just after the bell. From there it bled for six straight hours and closed at $6.57, 42% below the alert.
## Reality check - The close was half the regular-session high. Anyone who chased the morning rode a halving. - That $19.52 premarket print is the number pump accounts will quote. Nobody got filled there in size. - Partnership with no disclosed terms, on a company this small, is a headline — not revenue. - This already happened. It's a breakdown of why it ran, not a reason to buy it.
