Which Stocks Posted the Biggest One-Month Losses Across the Sectors?

As screened on Friday, October 23, 2026, nine laggards fell between 65.81% and 98.42% over the past month, and all are penny stocks at screen prices under $5. DarkIris (NASDAQ:DKI) lost 98.42% after a $6 million offering and a 1-for-50 consolidation, Hub Cyber Security (NASDAQ:HUBC) 96.26% after a third reverse split and a Nasdaq notice, and Wellchange (NASDAQ:WCT) 95.74% after a $7.5 million offering. CL Workshop Group (NASDAQ:NWGL) fell 93.63% facing a November 2 Nasdaq deadline, Treasure Global (NASDAQ:TGL) 89.53% despite 122% revenue growth and YYForce (NASDAQ:YFOR) 87.83% amid robotics announcements.

DarkIris: How Much of a 98.42% Drop Is the 1-for-50 Consolidation?

DarkIris was screened at $2.00, down 98.42% over the past month, 33.77% over the week and 11.11% on October 23. A 1-for-50 consolidation effective October 22 by itself cuts a per-share price reading by 98% (calculated), so the monthly figure is consistent with a comparison spanning that date. On October 8 it priced a $6 million offering of units at $1.44 with warrants exercisable at $2.04, and on October 6 shareholders approved a reverse split in two stages of 50-to-1, the second only if the closing price stays below $1.00.

Hub Cyber Security: What Does a Third Reverse Split Do to a $0.153 Stock?

Hub Cyber Security fell 96.26% over the past month to $0.153, including 60.78% over the week and 24.14% on October 23. A 1-for-25 split announced September 10, after 1-for-50 in April and 1-for-20 in June, cut the share count to about 1.8 million from about 44.9 million. Nasdaq's September 23 letter set a March 22, 2027 deadline to regain the $35 million minimum market value, and the equity is worth roughly $0.28 million (calculated). A pending $8.7 million sale of QPoint Group is meant mainly to repay debt.

Wellchange: What Did a 50 Million Share Offering at $0.15 Leave Behind?

Wellchange fell 95.74% over the past month to $0.3283, including 14.06% over the week. It priced 50 million shares at $0.15 for about $7.5 million on August 28, equal to $0.75 after the 1-for-5 reverse split effective September 8 (calculated), well above the screen price. That followed a 1-for-50 split on March 6. The Hong Kong-based software provider has announced no operating catalyst, and the one-month figure implies a price near $7.71 a month ago (calculated).

CL Workshop Group: How Large Is a $200 Million Offering Program Against a $5.3 Million Company?

CL Workshop Group, an integrated forestry company, fell 93.63% over the past month to $0.0796, including 65.09% over the week. On October 15 it named an exclusive sales agent for an at-the-market program of up to $200 million, about 38 times its roughly $5.3 million market value (calculated). Nasdaq's bid-price compliance period ends November 2, and regaining compliance needs ten consecutive closing bids of $1.00 or more. No reverse split announcement appears among the filings reviewed.

Treasure Global: Why Did Shares Fall 89.53% Despite 122% Revenue Growth?

Treasure Global fell 89.53% over the past month to $0.2199 even as preliminary fiscal 2026 results showed revenue up roughly 122% to about $5.17 million and a net loss narrowed about 53% to $11.1 million. A non-binding memorandum for a $38 million purchase of 51% of Mestiz Century Logic is about 25 times the $1.52 million market value shown on October 19 (calculated). Three board members agreed on October 15 to buy about $1.2 million of stock, with shares to be issued by December 4.

YYForce: Why Did a Run of Robot Announcements Coincide With an 87.83% Slide?

YYForce fell 87.83% over the past month to $0.2093, including 58.72% over the week. The shares closed down 45.51% on October 13, the day it announced a service-robot memorandum with a Singapore hotel precinct. First-half revenue rose 26.8% to $32.66 million, but gross margin fell to 10.1%, the net loss was $7.06 million and the outlook was withdrawn. A $20 million at-the-market agreement is about 9.5 times a market value near $2.1 million (calculated).

SMX (Security Matters): Can an Equity Line Fund Losses After Eight Reverse Splits?

SMX fell 81.49% over the past month to $1.76, including 53.32% over the week. Filings show eight reverse splits since January 2025 and a standby equity purchase agreement raised from $100 million to $250 million, under which about $50.5 million net had been drawn by June 30. The first-half net loss widened to $45.45 million from $24.62 million. No release in the period gives a financial reason for the slide.

ReTo Eco-Solutions: How Did a 20-for-1 Share Combination Change the Picture?

ReTo Eco-Solutions fell 75.52% over the past month to $0.83 after a $15 million registered direct offering in mid-September and a 20-for-1 share combination effective October 2, which cut shares from 145.8 million to about 7.3 million. Prices before and after the combination differ by a factor of 20 unless adjusted, and $0.83 sits below Nasdaq's $1.00 minimum bid. Fiscal 2025 revenue rose 84.3% to $3.37 million, but the net loss widened 47.7% to $12.34 million. Earnings are expected on November 3.

XCF Global: Does a 195.39 Million Share Resale Pool Outweigh Revenue Growth?

XCF Global fell 65.81% over the past month to $0.1573, the mildest decline of the nine. A business combination completed October 16 enlarged the share base, and a resale registration covers up to 195.39 million shares, about 47% of 415.3 million outstanding (calculated). Operations are growing: September gross product sales exceeded $12 million on about 1.4 million gallons, and on October 20 it agreed to acquire a renewable fuel facility in Paramount, California. Earnings are estimated for mid-November, though the company has not confirmed the date.

Biggest Laggards Compared: How Far Did Each Fall Behind Its Sector?

Against sector one-month moves, the shortfalls (calculated) are: Hub Cyber Security 106.11 points behind Commercial Services, which rose 9.85%; Treasure Global 99.38 and YYForce 97.68 behind the same group; DarkIris 95.73, Wellchange 93.05 and SMX 78.80 behind Technology Services, down 2.69%; CL Workshop Group 83.70 and ReTo 65.59 behind Non-Energy Minerals, down 9.93%; and XCF Global 78.51 behind Energy Minerals, up 12.70%. The steepest fall, DarkIris, is 32.61 points deeper than the mildest, XCF Global (calculated).

Share structure is the common thread. DarkIris, Wellchange, Hub Cyber Security, SMX and ReTo have completed or announced a reverse split in 2026, five of the nine (calculated). Financing is large against size: the CL Workshop Group program is about 38 times its market value, Treasure Global's proposed acquisition about 25 times and YYForce's facility about 9.5 times (calculated).

What to Watch Next: November 2 Nasdaq Deadline, November 3 ReTo Earnings and March 22, 2027

CL Workshop Group's compliance period ends November 2, and ReTo reports on November 3. XCF Global's results are estimated for mid-November, and Treasure Global's board placement is due by December 4. DarkIris must hold above $1.00 after its October 22 consolidation to avoid the second 50-to-1 stage, Wellchange faces possible further financing, and Hub Cyber Security has until March 22, 2027 to regain Nasdaq's market value requirement.
