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. That said, 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:

Tecnoglass (TGLS)

Market Cap: $1.88 billion

The first-ever Colombian company to trade on the NASDAQ, Tecnoglass (NYSE: TGLS) is a manufacturer of architectural glass, windows, and aluminum products.

Why Are We Wary of TGLS?

  1. Incremental sales over the last two years were much less profitable as its earnings per share fell by 1.7% annually while its revenue grew
  2. Capital intensity has ramped up over the last five years as its free cash flow margin decreased by 10.9 percentage points
  3. Waning returns on capital imply its previous profit engines are losing steam

Tecnoglass’s stock price of $41.62 implies a valuation ratio of 16.3x forward P/E. To fully understand why you should be careful with TGLS, check out our full research report (it’s free).

Frontier (ULCC)

Market Cap: $1.31 billion

Recognizable for the colorful animals adorning each aircraft tail, Frontier Group Holdings (NASDAQ: ULCC) is an ultra low-cost airline that provides budget-friendly flights throughout the United States and select international destinations in the Americas.

Why Do We Avoid ULCC?

  1. 3.7% annual revenue growth over the last two years was slower than its consumer discretionary peers
  2. Shrinking returns on capital from an already weak position reveal that neither previous nor ongoing investments are yielding the desired results
  3. Depletion of cash reserves could lead to a fundraising event that triggers shareholder dilution

Frontier is trading at $5.64 per share, or 0.3x forward price-to-sales. Dive into our free research report to see why there are better opportunities than ULCC.

One Small-Cap Stock to Buy:

American Superconductor (AMSC)

Market Cap: $2.23 billion

Founded in 1987, American Superconductor (NASDAQ: AMSC) has shifted from superconductor research to developing power systems, adapting to changing energy grid needs and naval technology requirements.

Why Are We Bullish on AMSC?

  1. Market share has increased this cycle as its 43.3% annual revenue growth over the last two years was exceptional
  2. Free cash flow margin grew by 24.5 percentage points over the last five years, giving the company more chips to play with
  3. Historical investments are beginning to pay off as its returns on capital are growing

At $46.25 per share, American Superconductor trades at 48.9x forward P/E. Is now a good time to buy? Find out in our full research report, it’s free.
