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.

These trade-offs can cause headaches for even the most seasoned professionals, which is why we started StockStory - to help you separate the good companies from the bad. Keeping that in mind, here is one small-cap stock that could amplify your portfolio’s returns and two that may have trouble.

Two Small-Cap Stocks to Sell:

Tennant (TNC)

Market Cap: $1.49 billion

As the world’s largest manufacturer of autonomous mobile robots, Tennant (NYSE: TNC) designs, manufactures, and sells cleaning products to various sectors.

Why Should You Dump TNC?

Sales trends were unexciting over the last two years as its 3% annual growth was below the typical industrials company
Earnings per share fell by 2.1% annually over the last two years while its revenue grew, showing its incremental sales were much less profitable
Free cash flow margin shrank by 4.4 percentage points over the last five years, suggesting the company is consuming more capital to stay competitive

Tennant’s stock price of $80.66 implies a valuation ratio of 13.2x forward P/E. To fully understand why you should be careful with TNC, check out our full research report (it’s free).

National Bank Holdings (NBHC)

Market Cap: $1.51 billion

Operating under familiar local brands like Community Banks of Colorado, Bank Midwest, and Bank of Jackson Hole, National Bank Holdings (NYSE: NBHC) operates regional banks across Colorado, Kansas, Missouri, Wyoming, Texas, and other western states, offering commercial, business, and consumer banking services.

Why Is NBHC Not Exciting?

Products and services are facing end-market challenges during this cycle, as seen in its flat sales over the last two years
Net interest margin dropped by 24 basis points (100 basis points = 1 percentage point) over the last two years, implying the firm’s loan book profitability fell as competitors entered the market
Projected 4.8 percentage point efficiency ratio increase over the next year signals its day-to-day expenses will rise

One Small-Cap Stock to Watch:

OSI Systems (OSIS)

Market Cap: $3.96 billion

With security scanners deployed at airports and borders worldwide and patient monitors used in hospitals across the globe, OSI Systems (NASDAQ: OSIS) designs and manufactures specialized electronic systems for security screening, patient monitoring, and optoelectronic applications.

Why Does OSIS Stand Out?

Market share has increased this cycle as its 15.8% annual revenue growth over the last two years was exceptional
Operating margin improvement of 2.6 percentage points over the last five years demonstrates its ability to scale efficiently
Earnings per share have massively outperformed its peers over the last two years, increasing by 22.7% annually
