U.S. stock markets are closed today (Sunday), but that doesn't mean traders are resting. A look at Friday's closing data — the last trading session — reveals several names that pulled extraordinary volume and extreme price moves, exactly the kind of stocks that capture day-trader and short-term speculator attention.

HCW Biologics (HCWB) — A 262% Surge

The standout name is HCW Biologics, a biotech company with a market cap of roughly $8.2 million. The stock surged 262% on Friday, with trading volume of nearly 390 million shares — an extraordinary figure for a company of this size.

HCW Biologics operates in the immunotherapy drug development space, a sector known for high volatility around clinical trial announcements and FDA decisions.

P3 Health Partners (PIII) — A 180% Jump

P3 Health Partners, a healthcare services company with a market cap of around $82 million, climbed 180% on volume exceeding 64 million shares. The company provides care management and administrative services to healthcare networks across the United States.

Murano Global Investments (MRNO) — Up 94%

UK-based real estate firm Murano Global Investments, with a market cap of roughly $45 million, completed a 94% surge on Friday. Daily volume reached approximately 322 million shares — many multiples of its normal trading average.

Broader Context: A Quiet Weekend, Traders Planning

With markets closed on Sunday, day traders are using the time for analysis and positioning. Current focus is on micro-caps with extreme volatility — small names that can move hundreds of percent in a single session. The healthcare sector in particular drew attention at the weekly close.

Important caveat: Micro-cap stocks posting triple-digit single-day gains are extremely risky. Volatility of this magnitude means equally sharp drawdowns are possible. This article does not constitute investment advice.
