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 are three mid-cap stocks to avoid and some other investments you should consider instead.
Masco (MAS)
Market Cap: $12.93 billion
Headquartered just outside of Detroit, MI, Masco (NYSE: MAS) designs and manufactures home-building products such as glass shower doors, decorative lighting, bathtubs, and faucets.
Why Are We Out on MAS?
- Absence of organic revenue growth over the past two years suggests it may have to lean into acquisitions to drive its expansion
- Estimated sales growth of 1.7% for the next 12 months is soft and implies weaker demand
- Eroding returns on capital suggest its historical profit centers are aging
At $65.61 per share, Masco trades at 15.7x forward P/E. Dive into our free research report to see why there are better opportunities than MAS.
Ball (BALL)
Market Cap: $14.7 billion
Started with a $200 loan in 1880, Ball (NYSE: BLL) manufactures aluminum packaging for beverages, personal care, and household products as well as aerospace systems and other technologies.
Why Are We Wary of BALL?
- Sales stagnated over the last two years and signal the need for new growth strategies
- Gross margin of 21.3% reflects its high production costs
- Ability to fund investments or reward shareholders with increased buybacks or dividends is restricted by its weak free cash flow margin of -0.3% for the last five years
Ball is trading at $54.92 per share, or 13.9x forward P/E. To fully understand why you should be careful with BALL, check out our full research report (it’s free).
Antero Resources (AR)
Market Cap: $11.85 billion
Holding roughly 521,000 net acres across West Virginia, Ohio, and Pennsylvania, Antero Resources (NYSE: AR) drills and produces natural gas, natural gas liquids, and oil from underground rock formations in the Appalachian Basin.
Why Does AR Worry Us?
- Sales trends were unexciting over the last five years as its 5.6% annual growth was below the typical energy upstream and integrated energy company
- Efficiency has decreased over the last five years as its EBITDA margin fell by 5.1 percentage points
Antero Resources’s stock price of $38.25 implies a valuation ratio of 8.5x forward P/E. Read our free research report to see why you should think twice about including AR in your portfolio.
