— Why it moved
Why VTAK Stock Doubled Today — July 8, 2026
Stale patent news met a 2.3-million-share float, and Catheter Precision ran 144% above yesterday's close before giving most of the spike back.
What moved VTAK stock
Catheter Precision is a medical device maker behind the VIVO line and the Cardionomix heart-failure portfolio. The catalyst was real but stale: on July 6 it announced two new patents — a European grant covering VT ablation targeting from signals stored in pacemakers and defibrillators, plus a second in the Cardionomix portfolio. The stock barely reacted that day; it jumped after hours on the 7th, and July 8 was the blow-off.
The mechanics
The float is 2.3 million shares, and that is most of the story. It gapped 71% into the bell and 189M shares turned the float over roughly 80 times — two-day-old patent filings don't do that on their own, momentum does.
VTAK by the numbers
The alert window
The alert fired at 9:25 AM, five minutes before the bell, at $1.22. The peak was $1.74 at 10:06 — a 41-minute window for 42.6%. A real-time reader had the open and the first half hour; everything after 10:06 was lower.
How VTAK's move ended
It spent the rest of the session bleeding and closed at $1.346, +10.3% from the alert — three quarters of the spike given back by the close. Trailing revenue is about $819K against quarterly losses near $1.7M, February's $36.5M institutional financing keeps the dilution tap on, and the stock is still down 95% from its 52-week high. This was the second fire in two weeks, and the June 24 run faded too. When a stock ignores its own news for two days and then gaps 71%, the buyers are trading the gap, not the patent.
