3 Penny Stocks to Watch Now: September 4, 2025 Edition

Penny stocks surge as retail traders chase explosive returns—here are three names catching fire this week.

Micro-Cap Momentum Plays

While Wall Street obsesses over blue-chips, these under-the-radar picks show unusual volume spikes and technical breakouts. Each trades under $5 with catalysts that could spark serious movement.

Sector-Specific Opportunities

From biotech innovators to emerging tech disruptors, these companies operate in high-growth niches. Their risk-reward profiles appeal to traders willing to stomach volatility for potential triple-digit runs.

Timing the Trade

Entry points matter more than fundamentals in this space—because let's be honest, most penny stock investors care more about charts than cash flow statements. Watch for volume confirmation and avoid chasing pumps.

Remember: these plays aren't for the faint-hearted. But for those who think 'due diligence' means reading two Twitter threads? Potential life-changing gains—or devastating losses—await.

We Leveraged the tool to pick the top three penny stocks with the highest Dollar Volume as of the close on September 3, 2025. Simply put, Dollar Volume is the number of shares traded on a particular day multiplied by the day’s share price.

(AIHS) – Senmiao is a Chinese technology company operating within the ride-hailing services sector, online automobile trading, and vehicle leasing. It leverages AI to enhance its offerings. On September 3, AIHS had a Dollar Volume of $668.75 million, while its stock price surged by 61%.

There was no specific news about Senmiao yesterday that could justify the stock price surge. However, the steep rise could be driven by speculative enthusiasm around its expansion in AI-driven urban mobility and rumors of potential partnerships with Chinese transportation firms.

(BTBD) – BT Brands owns and operates a diverse portfolio of fast-food restaurant concepts in the U.S. Yesterday, BTBD had a Dollar Volume of $318.87 million, accompanied by a stock price surge of nearly 64%.

BT Brands announced that it has entered into a definitive merger agreement with AERO Velocity to combine in an all-stock transaction, with Aero Velocity shareholders owning 89% of the combined company. The new company, named Aero Velocity Inc., will focus on advanced drone and AI technology for government and commercial use. The merger is expected to close by early 2026 and includes a $3 to $5 million equity investment from Aero Velocity shareholders.
