Parabolic Technologies (NASDAQ:PARA) (up USD 4.27, 252.45%): A Huge Jump on the Final Day of a Delisting Appeal Window

Parabolic Technologies (NASDAQ:PARA) rose 252.45% to USD 5.96 in regular trading on November 3, 2026, a gain of USD 4.27. No company announcement dated November 2 or November 3, 2026 was identified as a direct trigger. The jump arrived on the last day to appeal a Nasdaq delisting determination dated October 27, 2026.

The company is the new name of Banzai International, a Marketing and sales software provider. Preliminary Q3 2026 Revenue was about USD 4.7 million, up 65% from USD 2.8 million, and full results are scheduled for November 16, 2026. The main risk is listing status: without a successful appeal, trading would be suspended at the open on November 5, 2026, and more authorized shares leave room for dilution.

Rising Dragon Acquisition (NASDAQ:RDAC) (up USD 5.92, 116.08%): A SPAC Surges After a Merger Is Called Off

Rising Dragon Acquisition (NASDAQ:RDAC) rose 116.08% to USD 11.02 in regular trading on November 3, 2026, a gain of USD 5.92. A company press release dated November 3, 2026 announced a mutual termination of its merger agreement with HZJL Cayman Limited. Neither party owes a termination fee.

It is a blank check company. Its trust account held USD 18,370,925 as of June 30, 2026, which works out to roughly USD 10.90 per redeemable share (calculated). With no announced target and thin trading, a 116.08% move can reverse sharply.

Cerenome (NASDAQ:CNSY) (up USD 1.58, 92.40%): A Penny Stock Rally Ahead of Interim Trial Data

Cerenome (NASDAQ:CNSY), formerly Plus Therapeutics, rose 92.40% to USD 3.29 in regular trading on November 3, 2026, a gain of USD 1.58. No press release or filing dated October 30 to November 3, 2026 was identified as a clear catalyst, so the move looks like momentum ahead of a data event.

Interim results from ReSPECT-LMM, covering the first 10 patients, will be presented on November 13, 2026. The company reported trailing twelve-month revenue of about USD 4.20 million against a net loss of about USD 26.09 million. A financing Facility of up to USD 20 million make dilution a continuing risk, and early stage data come from small patient numbers.

Mercer International (NASDAQ:MERC) (up USD 0.0938, 74.44%): Shares Climb as a Prepackaged Chapter 11 Plan Takes Shape

Mercer International (NASDAQ:MERC) rose 74.44% to USD 0.2198 in regular trading on November 3, 2026, a gain of USD 0.0938. The move follows a November 2, 2026 announcement of a recapitalization that would exchange about USD 1.1 billion of senior notes for Equity through a prepackaged Chapter 11 case.

The plan would remove about USD 96 million of annual cash interest. The risk for shareholders is stark: existing common stock would be cancelled, with holders receiving about 8.5% of the new common stock. The company also expects a Nasdaq delisting notice, and third quarter results are due on November 5, 2026.

Hub Cyber Security (NASDAQ:HUBC) (up USD 0.0290, 35.37%): A Penny Stock Moves After a Court Hearing Over the QPoint Sale

Hub Cyber Security (NASDAQ:HUBC) rose 35.37% to USD 0.1110 in regular trading on November 3, 2026, a gain of USD 0.0290. No company release or filing dated November 2 or November 3, 2026 was identified. A Tel Aviv court hearing on a receiver application over the QPoint share pledge was set for November 1, 2026.

The QPoint divestiture was agreed on August 4, 2026 for about USD 8.7 million. The company faces a Nasdaq compliance deadline of March 22, 2027 for the USD 35 million Market Value requirement, and a 1-for-25 reverse split cut shares outstanding to about 1.8 million, so a gain of this size can reverse quickly.

Where Things Stand

The five gainers share a pattern: sharp moves in small, thinly traded names where the company itself explained little. Two face listing pressure, one is a shell, one is restructuring Debt and one awaits clinical data. Dates worth watching include the Parabolic Technologies results on November 16, 2026, the Mercer International report on November 5, 2026, the Cerenome data on November 13, 2026 and any court ruling on the QPoint sale.
