Small-cap stocks can be incredibly lucrative investments because their lack of analyst coverage leads to frequent mispricings. However, these businesses (and their stock prices) often stay small because their subscale operations make it harder to expand their competitive moats.

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 could be down big.

Two Small-Cap Stocks to Sell:

EnerSys (ENS)

Market Cap: $4.98 billion

Supplying batteries that power equipment as big as mining rigs, EnerSys (NYSE: ENS) manufactures various kinds of batteries for a range of industries.

Why Is ENS Not Exciting?

1. Declining unit sales over the past two years indicate demand is soft and that the company may need to revise its strategy
2. Demand will likely be soft over the next 12 months as Wall Street’s estimates imply tepid growth of 1.6%
3. Competitive supply chain dynamics and steep production costs are reflected in its low gross margin of 26.1%

At $131.37 per share, EnerSys trades at 12.3x forward P/E. To fully understand why you should be careful with ENS, check out our full research report (it’s free for active Edge members).

Columbia Banking System (COLB)

Market Cap: $8.11 billion

Created through the merger of two Pacific Northwest banking institutions with deep regional roots, Columbia Banking System (NASDAQ: COLB) operates Umpqua Bank, providing commercial, consumer, and wealth management services across eight western states.

Why Are We Hesitant About COLB?

1. Annual tangible book value per share declines of 1.2% for the past five years show its capital management struggled during this cycle

Columbia Banking System’s stock price of $27.75 implies a valuation ratio of 1x forward P/B. Read our free research report to see why you should think twice about including COLB in your portfolio.

One Small-Cap Stock to Watch:

Impinj (PI)

Market Cap: $4.83 billion

Founded by Caltech professor Carver Mead and one of his students Chris Diorio, Impinj (NASDAQ: PI) is a maker of radio-frequency identification (RFID) hardware and software.

Why Do We Watch PI?

1. Market share has increased this cycle as its 20.2% annual revenue growth over the last five years was exceptional
2. Incremental sales over the last five years have been highly profitable as its earnings per share increased by 49.4% annually, topping its revenue gains
3. Free cash flow margin jumped by 15.8 percentage points over the last five years, giving the company more resources to pursue growth initiatives, repurchase shares, or pay dividends

Impinj is trading at $162 per share, or 61x forward P/E. Is now a good time to buy? See for yourself in our in-depth research report, it’s free for active Edge members.
