Mid-cap stocks have the best odds of scaling into $100 billion corporations thanks to their tested business models and large addressable markets. But the many opportunities in front of them attract significant competition, spanning from industry behemoths with seemingly infinite resources to small, nimble players with chips on their shoulders.
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 are two mid-cap stocks with long growth runways and one that may have trouble.
One Mid-Cap Stock to Sell:
CooperCompanies (COO)
Market Cap: $11.63 billion
With a history dating back to 1958 and a portfolio spanning two distinct healthcare segments, Cooper Companies (NASDAQ: COO) develops and manufactures medical devices focused on vision care through contact lenses and women's health including fertility products and services.
Why Does COO Fall Short?
- Muted 6.4% annual revenue growth over the last two years shows its demand lagged behind its healthcare peers
- Free cash flow margin dropped by 6 percentage points over the last five years, implying the company became more capital intensive as competition picked up
- Below-average returns on capital indicate management struggled to find compelling investment opportunities
At $59.62 per share, CooperCompanies trades at 12.9x forward P/E. Check out our free in-depth research report to learn more about why COO doesn’t pass our bar.
