PRFX is trading at 5% up now at $1.43 after a volatile stretch driven by enthusiasm around its DeepSolar Predict AI renewable-energy platform and PRF‑110 post‑operative pain candidate, which previously sent the stock up over 200% on headlines. Today’s move looks like continuation of speculative, momentum-driven trading in a low-float micro-cap rather than a fresh, company-specific catalyst, with no new filings or press releases reported so far.
