Mid-cap stocks often strike the right balance between having proven business models and market opportunities that can support $100 billion corporations. However, they face intense competition from scaled industry giants and can be disrupted by new innovative players vying for a slice of the pie.

These dynamics can rattle 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 mid-cap stock with massive growth potential and two that could be down big.

Two Mid-Cap Stocks to Sell:

F5 (FFIV)

Market Cap: $15.07 billion

Originally named after the F5 tornado, the most powerful on the meteorological scale, F5 (NASDAQ:FFIV) provides security and delivery solutions that protect applications across cloud, data center, and edge environments for large organizations.

Why Does FFIV Worry Us?

  1. ARR has dropped by 12.3% over the last year, suggesting it lost long-term deals and renewals
  2. Estimated sales growth of 1.6% for the next 12 months implies demand will slow from its two-year trend
  3. Operating profits and efficiency rose over the last year as it benefited from some fixed cost leverage

At $258.88 per share, F5 trades at 4.8x forward price-to-sales. If you’re considering FFIV for your portfolio, see our FREE research report to learn more.

Encompass Health (EHC)

Market Cap: $10.83 billion

With a network of 161 specialized facilities across 37 states and Puerto Rico, Encompass Health (NYSE:EHC) operates inpatient rehabilitation hospitals that help patients recover from strokes, hip fractures, and other debilitating conditions.

Why Are We Wary of EHC?

  1. Annual revenue growth of 4.7% over the last five years was below our standards for the healthcare sector
  2. Capital intensity has ramped up over the last five years as its free cash flow margin decreased by 1.3 percentage points

Encompass Health is trading at $107.67 per share, or 19.1x forward P/E. Dive into our free research report to see why there are better opportunities than EHC.

One Mid-Cap Stock to Watch:

Toast (TOST)

Market Cap: $21.34 billion

Born from the frustrations of three friends waiting too long for their restaurant bill, Toast (NYSE:TOST) provides a cloud-based digital technology platform with software, payment processing, and hardware solutions built specifically for restaurants.

Why Are We Fans of TOST?

  1. Ability to secure long-term commitments with customers is evident in its 31.3% ARR growth over the last year
  2. Sales outlook for the upcoming 12 months implies the business will stay on its desirable two-year growth trajectory

Toast’s stock price of $36.27 implies a valuation ratio of 3.1x forward price-to-sales. Is now the right time to buy? See for yourself in our full research report, it’s free for active Edge members.
