Hindsight Markets Recaps Small-cap stocks on September 23, 2026
ONCO, September 23: a quiet day, then two halts and $1.15
ONCO opened near its previous close, then ran to $1.15 through two halts during the session.
What happened
No news, then a run
ONCO had no headline today and sat near its $0.68 close until mid-afternoon. Then it ran from $0.67 to $0.88 by 3:02, up 30%.
Stop It's 3:07. ONCO is at $0.94, against a $0.68 previous close. It ran hard over the last few minutes, and $1.00 is just above. Would you buy here?
Press play: the real Level 2, tape and chart run from 3:04 p.m. and stop at 3:07 p.m. ET for your call.
It kept going to $1.01. At 3:07:48 a volatility pause halted it there.
A lower reopen
The reopen at 3:12:48 came 10% lower, at $0.91.
It then swung between $0.84 and $1.10. By 3:20 more shares had traded than the whole float. A large bid built at $1.07, just under the price.
A bid at $1.07
Stop It's 3:24. ONCO is at $1.09. A large bid has been building at $1.07, just below, since 3:23. Would you buy here?
Press play: the real Level 2, tape and chart run from 3:21 p.m. and stop at 3:24 p.m. ET for your call.
It topped at $1.15 that minute. Then sellers ate the $1.07 bid: 126K shares in 12 seconds. At 3:27:04 a second halt froze it at $0.92. It fell to $0.72 by 3:37 and closed at $0.91.
What to take from it: Here the big bid did not hold; sellers ate it in seconds and the price fell.
