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. That said, here are three small-cap stocks to swipe left on and some alternatives you should look into instead.

Standex (SXI)

Market Cap: $3.03 billion

Holding over 500 patents globally, Standex (NYSE: SXI) is a manufacturer and distributor of industrial components for various sectors.

Why Does SXI Give Us Pause?

1. Annual revenue growth of 6% over the last two years was below our standards for the industrials sector
2. Free cash flow margin dropped by 4.4 percentage points over the last five years, implying the company became more capital intensive as competition picked up
3. Diminishing returns on capital suggest its earlier profit pools are drying up

At $249.98 per share, Standex trades at 28.6x forward P/E. If you’re considering SXI for your portfolio, see our FREE research report to learn more.

Trinity (TRN)

Market Cap: $2.19 billion

Operating under the trade name TrinityRail, Trinity (NYSE: TRN) is a provider of railcar products and services in North America.

Why Do We Pass on TRN?

1. Products and services are facing significant end-market challenges during this cycle as sales have declined by 2.2% annually over the last five years
2. Sales are projected to tank by 3.5% over the next 12 months as its demand continues evaporating
3. Free cash flow margin dropped by 23.4 percentage points over the last five years, implying the company became more capital intensive as competition picked up

Trinity’s stock price of $27.35 implies a valuation ratio of 10.7x forward P/E. Read our free research report to see why you should think twice about including TRN in your portfolio.

Enphase (ENPH)

Market Cap: $4.58 billion

The first company to successfully commercialize the solar micro-inverter, Enphase (NASDAQ: ENPH) manufactures software-driven home energy products.

Why Do We Steer Clear of ENPH?

1. Declining unit sales over the past two years suggest it might have to lower prices to accelerate growth
2. Falling earnings per share over the last two years has some investors worried as stock prices ultimately follow EPS over the long term
3. 9.2 percentage point decline in its free cash flow margin over the last five years reflects the company’s increased investments to defend its market position

Enphase is trading at $34.97 per share, or 17.3x forward P/E. Dive into our free research report to see why there are better opportunities than ENPH.
