Actelis Networks, Firefly Neuroscience, and Mobix Labs are the three Penny stocks to watch today, according to MarketBeat’s stock screener tool. Penny stocks are low-priced shares of very small or thinly traded companies—commonly defined in the U.S. as trading under $5 per share—and are often listed on over-the-counter markets or the “pink sheets” rather than major exchanges. They are highly volatile and illiquid, carrying elevated risk of large losses (and occasional large percentage gains) and are more susceptible to price manipulation and limited public information, so they are considered speculative investments. These companies had the highest dollar trading volume of any Penny stocks within the last several days.
