— Why it moved
Why AMIX Stock Quadrupled Today — August 4, 2026
A patent press release sparked a massive low-float squeeze on Autonomix Medical that gave traders a 291.7 percent window despite early turbulence.

What moved AMIX stock
Autonomix Medical is a micro-cap medical device company developing nerve-sensing catheter systems. Before the session's start, they issued a press release announcing a broad U.S. patent approval covering cancer-related nerve mapping technology. That single PR gave retail momentum chasers all the reason they needed to pile in.
The mechanics
This move wasn't about the intrinsic value of a patent. It was driven by a tiny floating supply of just 526,438 shares. Over 120 million shares flipped throughout the day, cycling the float over two hundred times as market makers scrambled for liquidity.
AMIX by the numbers
The alert window
The alert hit at 9:32 AM at $6.30. Anyone jumping in immediately sat through a harsh 16.8 percent drawdown as initial chasers dumped. After shaking those hands out, the stock pushed steadily higher over 372 minutes to peak at $24.68 at 3:44 PM, delivering a massive 291.7 percent run for those who held through the initial drop.
How AMIX's move ended
Prices cooled off slightly toward the bell, closing at $19.50 for a 209.5 percent gain from our alert. It was a massive tradeable window, but do not forget the context here. The company filed a debt prospectus supplement on July 31, so dilution risk remains a real factor.
The tell: When volume exceeds a tiny float by a factor of two hundred, fundamental details take a backseat to pure supply exhaustion.
