New York, Dec 23, 2025 — US markets witnessed sharp stock-specific action on Tuesday, with extreme gains and steep declines dominating the list of trending movers, reflecting heightened speculative activity in micro- and small-cap counters.
🚀 Top Gainers Grabbing Investor Attention
Several low-float stocks posted outsized gains, becoming the most discussed names across trading platforms:
PicoCELA Inc. (PCLA) skyrocketed over 192%, emerging as the session’s top gainer amid heavy volume.
Australian Oilseeds Holdings (COOTW) surged 77%, continuing strong speculative momentum.
Hub Cyber Security (HUBCZ) climbed 71%, driven by renewed interest in cybersecurity-linked plays.
Nvni Group (NVNIW) advanced 63%, while
Sran & Company (SWAGW) rose 61%, rounding out the list of major gainers.
Market participants noted that most of these moves were concentrated in thinly traded names, often driven by short covering, retail momentum, or company-specific developments.
📉 Sharp Decliners Signal High Risk
On the downside, several stocks faced aggressive selling pressure:
X3 Holdings (XTKG) plunged over 90%, marking one of the steepest single-day declines in recent sessions.
Starfighters Space (FJET) dropped 59%, erasing recent gains.
WM Technology (MAPSW) fell 48%,
