Investors looking for hidden gems should keep an eye on small-cap stocks because they’re frequently overlooked by Wall Street. Many opportunities exist in this part of the market, but it is also a high-risk, high-reward environment due to the lack of reliable analyst price targets.

Luckily for you, our mission at StockStory is to help you make money and avoid losses by sorting the winners from the losers. Keeping that in mind, here is one small-cap stock that could be the next big thing and two that could be down big.

Two small-cap stocks to sell:

Ridgepost Capital (RPC)

Market cap: $1.02 billion

Operating as a bridge between institutional investors and hard-to-access private market opportunities, Ridgepost Capital (NYSE: RPC) is an alternative asset management firm that provides access to private equity, venture capital, impact investing, and private credit opportunities in the middle and lower middle markets.

Why Do We Think Twice About RPC?

1. Incremental sales over the last two years were less profitable as its 5.7% annual earnings per share growth lagged its revenue gains

At $9.29 per share, Ridgepost Capital trades at 8.2x forward P/E. If you’re considering RPC for your portfolio, see our FREE research report to learn more.

Old National Bank (ONB)

Market cap: $9.54 billion

Tracing its roots back to 1834 when Andrew Jackson was president, Old National Bancorp (NASDAQ: ONB) is a bank holding company that provides commercial and consumer loans, deposit services, wealth management, and treasury solutions primarily throughout the Midwest region.

Why Does ONB Fall Short?

1. Estimated net interest income growth of 5.7% for the next 12 months implies demand will slow from its five-year trend
2. Performance over the past five years shows its incremental sales were less profitable, as its 6.9% annual earnings per share growth trailed its revenue gains
3. 3.1% annual tangible book value per share growth over the last five years was slower than its banking peers

Old National Bank’s stock price of $25.21 implies a valuation ratio of 1.1x forward P/B. Dive into our free research report to see why there are better opportunities than ONB.

2. Revenue outlook for the upcoming 12 months is outstanding and shows it’s on track to gain market share
