3 European Penny Stocks With Market Caps Up To €100M

The European stock market has been buoyed by expectations of a U.S. Federal Reserve rate cut, with major indices like the STOXX Europe 600 Index seeing gains. In this context, penny stocks—typically smaller or newer companies—remain an intriguing investment area for those looking to explore growth opportunities beyond mainstream options. Though often considered niche, these stocks can offer a blend of affordability and potential when backed by strong financials, making them worth considering for investors seeking long-term success in under-the-radar companies.

Market Cap: €82.74M

Kamux Oyj, with a market cap of €82.74 million, operates in the used car sector across Finland, Sweden, and Germany.

Market Cap: NOK1.12B

Instabank ASA, with a market cap of NOK1.12 billion, offers banking products in Norway. Despite a seasoned management team and stable weekly volatility, the bank faces challenges such as declining net profit margins (26.5% from 31.8% last year) and negative earnings growth (-0.7%) over the past year compared to industry averages. While trading below its estimated fair value, Instabank's high level of bad loans (8.5%) and low return on equity (8.8%) are concerns for investors in penny stocks seeking stability or rapid growth potential amid its primarily low-risk funding structure and appropriate loan levels.
