— Why it moved
Why CUPR Stock Tripled Then Halved Today — June 12, 2026
Cuprina's first Stock Pulse fire: a reverse-split microcap regained Nasdaq compliance and tripled on a 921K float — three days before the MEDIFLY FDA news that made the ticker famous.
## What moved it The news on the day was housekeeping: a 6-K saying Cuprina regained Nasdaq minimum-bid compliance after its 1-for-8 reverse split, cancelling a July delisting hearing. The tape treated it as a green light anyway. The bigger headline — FDA 510(k) clearance for MEDIFLY, its maggot-based wound debridement product — didn't drop until the following Monday, so the June 12 move ran ahead of anything fundamental. The ticker fired Stock Pulse again on June 24; that re-run is broken down separately, and it topped in a minute.
## The mechanics A 921K-share float on a $6.5M cap, freshly compressed by the reverse split. It gapped 93% and traded 83M shares, turning the float over about ninety times. That structure is how $2.41 becomes $8.23 in a morning.
## Numbers - Cap: ~$6.5M / float: 921K - Day volume: 83M (float turned ~90x) - Prev close: $2.41 → gap +93% - 52w range: $1.76–$76 split-adjusted
## Where it ended up Stock Pulse flagged it premarket at 9:15 AM, $4.61. Forty-one minutes later it printed $8.23. Then the unwind — it gave back the entire post-alert move and closed at $3.97, 14% below the alert while still up 65% on the day.
## Reality check - The whole run from alert to top lasted under an hour, and the close came back below the alert price. - Compliance-regained is not a business event. The FDA clearance was real news, but it wasn't public yet on June 12. - This already happened. It's a breakdown of why it ran, not a reason to buy it.
