$BEAT is stealing the spotlight after a meteoric 92% surge, marking its fifth consecutive day of gains. The spike comes on the heels of FDA clearance for HeartBeam’s 12-lead ECG synthesis software, a breakthrough that could redefine cardiac monitoring. Trading volume has exploded to 260 million shares, far above the average, reflecting a surge of investor interest and bullish sentiment.

$ENVB soared nearly 74% in after-hours trading, fueled by a combination of strong news flow and speculative enthusiasm. Enveric Biosciences appears to be benefiting from growing investor confidence in its pipeline, and the stock’s jump suggests that traders are pricing in potential near-term catalysts. After-hours activity indicates heightened demand as the market digests recent developments.

$IRBT continues its rally with a 48% jump, driven largely by its status as a heavily shorted stock. Short interest has risen to 13% of the float, creating a potential short squeeze scenario. Elevated trading volume underscores the intensity of buying pressure, signaling that market sentiment has swung sharply in favor of the robot-maker.

$PLAB gained 45% after delivering strong Q4 results and raising guidance for Q1. Photronics beat earnings and revenue estimates, reporting non-GAAP EPS of $0.60 and revenue of $215.77 million. The company also outlined a $330 million CapEx plan, targeting U.S. and Korean expansion amid growing AI and high-end IC packaging demand. Traders responded enthusiastically to the combination of solid financial performance and aggressive growth plans.

$SIDU climbed nearly 42% as Sidus Space completed the LizzieSat-3 commissioning, advancing its goal of providing AI-driven on-orbit data services. The milestone represents tangible progress in its space technology offerings, and investors are rewarding the company’s execution with a surge in trading volume and stock price.

$WRBY rose 27% after breaking above average analyst price targets. Warby Parker’s stock is signaling renewed optimism among investors, even as its RSI shows overbought conditions, suggesting momentum-driven buying has dominated the session.

On the downside,
$RUBI has fallen for the fifth consecutive day, losing 15%, reflecting lingering investor caution.

$EVTL dropped 17% despite news of expansion into UK and French Riviera airspace, indicating that broader market sentiment may be outweighing strategic developments.

$MIND declined 24% following its Q3 call, even with promising post-quarter orders, suggesting concerns over near-term execution.

$MBRX fell 27% after announcing warrant exercises, while $TGL plunged 40% after a registered direct offering, highlighting dilution concerns and market skepticism.
