  • From news to the move: the first trade 20% above the previous close came less than a minute after the latest news item before it (PRNewsWire, 4:28 p.m.).
  • Volume, from the one-minute bars: 104 shares before the 9:30 a.m. open (0%), 5 in the first 30 minutes (0%), and 1.78 million in the rest of the day to 8 p.m. (100%).
  • Float rotation, the volume since 4 a.m. against the float of 787,731 shares: past it once at 4:37 p.m., twice at 5:50 p.m.
  • Other days BIYA met the small-cap rule in our recaps: 3, the latest on October 7, 2026.
  • The next session, September 30, 2026, it was down 2.4% from its previous close at the 4:00 p.m. close.

On the day's lists: the intraday runners, after-hours movers. It is here because it met the small-cap rule on the intraday runners: price $2 to $20, up 10% or more, relative volume 5× or more, float under 20 million shares, its high reached $1 or more and it started the day at $20 or under (the rule every page uses).

Analysis

Written by AI from the facts above and checked against them, number by number. A reading of the price action, not advice.

BIYA spent the regular session going nowhere, opening at 2.03 after a 1.9% gap down and trading between 2.00 and 2.07 before its last print under the bell at 2.04. Nearly all of the 1.78 million shares came after the close rather than during the day, since only 104 shares traded before the open and 5 in the first 30 minutes. The catalyst arrived at 4:28 p.m. with the first-half fiscal 2026 results from PRNewsWire, and the first trade 20% above the previous close followed within a minute. After-hours price reached 2.74 at 4:28 p.m., and by 4:37 p.m. volume had passed the whole 787,731-share float, then passed it twice by 5:50 p.m. The exchange's halt feed shows no halts, so the thin float rotated without a pause.
