10. Yunhong Green CTI Ltd. (NASDAQ:YHGJ)
Yunhong Green, formerly CTI Industries, rallied by 64 percent last week to close at $1 apiece as investors gobbled up shares in the company to boost its price above the $1 minimum requirement of the Nasdaq exchange to remain as a listed firm.
On October 21, YHGJ received a letter from Nasdaq notifying the company of its noncompliance with the minimum threshold. The letter was based on its share price, which fell below the $1 level for 30 consecutive days since September 10, 2024.
YHGJ said it was given 180 days upon receipt of the letter, or until April 21, 2025, to comply with the threshold; otherwise, it could face a potential delisting.
To meet the requirements, the closing bid price of Yunhong Green CTI’s common stock must reach $1.00 or more per share for at least 10 consecutive business days within this period.

2. CervoMed Inc. (NASDAQ:CRVO)
CervoMed saw its share prices increase by 191 percent on Friday versus its $2.21 close on March 7 following positive results from the extension phase of its phase 2b clinical study of Neflamapimod for the treatment of Dementia with Lewy Bodies (DLB).
A total of 159 participants enrolled in the initial phase of the study. Of the number, 152 completed the initial phase, and 149 entered the extension phase, during which all participants received Neflamapimod.
In a statement last week, John-Paul Taylor, professor of translational dementia research at Newcastle University in the UK, said that the results from the extension phase of the study were highly persuasive.
DLB is the third most common degenerative disease of the brain after Alzheimer’s disease (AD) and Parkinson’s disease. According to CRVO, patients with the disease accumulate protein deposits called Lewy bodies in the brain’s nerve cells. This negatively affects cognitive ability, including attention, judgment, and reasoning, along with motor function.
