Curis, Inc. (NASDAQ:CRIS) (up USD 0.5964, 83.54%): Thin Cash and No Trigger Identified

Curis (NASDAQ:CRIS) rose 83.54%, or USD 0.5964, to USD 1.3103 in pre-market trading on November 4, 2026, implying a Tuesday close of about USD 0.7139 (calculated). No press release, filing or clinical update dated November 2 to November 4, 2026 was identified, so the jump looks like speculative momentum in a very small biotech penny stock.

Cash was USD 5.1 million at June 30, 2026, down from USD 15.0 million at March 31, and the first half net loss was USD 32.8 million. A 1-for-20 reverse split took effect on July 2, 2026, and an August offering raised about USD 4.8 million net. Dilution is the main risk.

Darkiris Inc. (NASDAQ:DKI) (up USD 0.8297, 55.30%): A Small Mobile Games Operator Spikes

Darkiris (NASDAQ:DKI) rose 55.30%, or USD 0.8297, to USD 2.33 in pre-market trading on November 4, 2026, against a calculated Tuesday close of about USD 1.5003. No press release, filing or Earnings report dated November 2 to November 4, 2026 was identified, so the move appears to be momentum in a thinly traded small cap.

The Hong Kong based mobile games publisher reported fiscal 2025 revenue of USD 10.08 million, up 27.3%. It posted a net loss of USD 8.64 million, mostly from about USD 8.81 million of share based compensation, and cash was USD 1.80 million at September 30, 2025. As a Penny Stock it carries dilution risk, and it had received a Nasdaq notice over the USD 1.00 minimum bid price.

Helport AI Limited (NASDAQ:HPAI) (up USD 0.1024, 42.56%): Autonomous AI Labor Release Is a Plausible Catalyst

Helport AI (NASDAQ:HPAI) rose 42.56%, or USD 0.1024, to USD 0.343 in pre-market trading on November 4, 2026, from a calculated Tuesday close of about USD 0.2406. A company press release dated November 3, 2026 described moving a Southeast Asian Fintech customer toward autonomous AI labor, with a target of about 300 AI workforce units by the end of November 2026. The company has not linked the share move to that release.

First half 2026 revenue rose 7.7% to USD 17.7 million, but the company swung to a net loss of USD 1.7 million and gross Margin slipped to 51.4% from 54.6%. It also filed a Form NT 20-F on November 3, a late report notice whose contents were not reviewed, which is a compliance risk for a penny stock.

MIRA Pharmaceuticals, Inc. (NASDAQ:MIRA) (up USD 0.0911, 17.59%): No Fresh News for a Cash Strapped Biotech

MIRA Pharmaceuticals (NASDAQ:MIRA) gained USD 0.0911, or 17.59%, to USD 0.6089 in pre-market trading on November 4, 2026, from a calculated Tuesday close near USD 0.5178. No announcement dated November 2 to November 4, 2026 was identified, so momentum in low priced biotech shares is a possible driver, though not a confirmed one.

The latest items are pipeline updates, including a company press release dated October 22, 2026 on rat study results for oral MIRA-55 and a September 17, 2026 update that the Ketamir-2 Phase 2a study advanced toward site initiation. Cash was USD 3,609,442 at June 30, 2026, and the 10-Q raised substantial doubt about going concern.

PowerCompute, Inc. (NASDAQ:PWCM) (up USD 0.0904, 15.87%): Bitcoin Loan Cleared, No Fresh Trigger

PowerCompute (NASDAQ:PWCM) rose USD 0.0904, or 15.87%, to USD 0.66 in pre-market trading on November 4, 2026, from a calculated Tuesday close near USD 0.5696. No company release or filing dated November 2 to November 4, 2026 was identified, so no catalyst can be named.

According to a company press release dated October 8, 2026, the company repaid its Arch Facility with 267.4 BTC, cutting secured debt to USD 1.25 million at September 30, 2026 from USD 23.70 million a month earlier. Bitcoin held fell to 63.7 BTC. A proxy statement dated October 21, 2026 proposes another reverse split, and the Quarterly Report carried going concern language.

Where Things Stand

Four of these five penny stocks moved with no company announcement identified, while Helport AI had a November 3 release that may be a catalyst. Cash runway and dilution run through the group, from Curis and MIRA Pharmaceuticals to Darkiris and PowerCompute. Pre-market gains on thin Volume can fade quickly once regular trading opens.
