PRISM Mid-Day Movers: Cybersecurity and MedTech are Today’s Leaders.

BIO-key International Inc. (NASDAQ: BKYI) shares surged 86.99% to $3.1415 by mid-day , up $1.4615 from Monday’s $1.68 close. The stock had reached $4.66 earlier in the session before retreating, but remained sharply higher on volume of more than 146 million shares—compared with average daily volume of about 98,000. BIO-key also announced a partnership with Al Majlis Group to expand its identity-security business across the Arabian Gulf, though the quote data alone cannot establish what drove the rally.

Quantum-Si Incorporated (NASDAQ: QSI) shares were up 24.03% at $0.986 today, gaining $0.191 from Monday’s $0.795 close. The stock had reached $1.00 during the session, while volume topped 14.4 million shares—more than five times its average daily volume of roughly 2.6 million. The move followed Quantum-Si’s release of interim data for its Proteus protein-sequencing platform, although the quote data alone does not establish what drove the gain.
