We recently published a list of 10 Penny Stocks With Huge Upside Potential According To Analysts. In this article, we are going to take a look at where Rapid Micro Biosystems, Inc. (NASDAQ:RPID) stands against other penny stocks with the biggest upside potential.

Penny stocks trade below $5 and attract investors looking for high returns with a small initial investment. These stocks are often associated with small-cap and mid-cap companies, which have traditionally outperformed large-cap stocks due to their growth potential and higher risk. However, in recent years, these smaller firms have struggled to keep pace, as large-cap stocks—particularly major tech companies—have led market gains. A key factor behind this trend is the changing makeup of major stock indices. The broader market, heavily influenced by a handful of mega-cap stocks, has skewed overall market performance. If the so-called Magnificent Seven stocks were excluded, the wider market’s advantage over the small-cap Russell index would be significantly reduced. Historically, small-cap stocks have tended to outperform large caps following periods of market volatility.

At the end of December 2024, Fundstrat’s Tom Lee told CNBC that with the Fed cutting rates and a pro-business administration taking over, companies would likely see 2025 as a prime time for expansion, including mergers and acquisitions. He believes this will create a strong market for small and mid-cap stocks, with financials, cyclicals, and industrials benefiting the most. Lee also pointed out that Trump’s tariff policies and potential labor market disruptions from mass deportations could impact the stock market. Another risk is if the Fed focuses too much on inflation and weakens the labor market. On a different yet interesting note, he predicted Bitcoin could hit $250,000 in 2025, with Ethereum reaching $5,000-$6,000. He was also optimistic about Solana and other altcoins.

Similarly, Jill Carey Hall, who is BofA’s Head of US Small/Mid Cap Strategy, recently commented that financials and healthcare tend to see more mergers and acquisitions under Republican administrations, which could mean a strong market in 2025 if macro conditions stay favorable. She expects banks to benefit from a more relaxed regulatory environment, improving their margins and efficiency. While there is optimism around deregulation for small-cap stocks, she cautioned that in the recent past, they did not perform as well despite deregulation because their success was tied to tariffs, trade policies, and the manufacturing recession.

Further insights came from Chris Retzler, portfolio manager for Needham’s Small Cap Growth Fund, who shared his outlook for small-caps on CNBC’s Squawk Box on January 17, 2025. He noted that small-cap companies are looking for policy certainty, and once the new administration’s direction becomes clearer, we could see growth accelerate. Globally, the EV sector is thriving, even as it faces some hurdles in the United States.

Meanwhile, innovation in semiconductors, new materials, and infrastructure, especially data centers, is driving investment, creating opportunities for small caps as well. Retzler emphasized that if the government prioritizes American manufacturing, more infrastructure will be needed, benefiting small-cap stocks. He also highlighted the potential upside of moderate, well-implemented tariff policies and deregulation, which could boost M&A activity. When small caps are acquired and integrated into larger platforms, it helps recycle assets and reduce costs. IPOs may soon pick up, and Retzler sees a strong and optimistic market for small caps in the long run.
