Many investors pay attention to mid-cap stocks because they have established business models and expansive market opportunities. However, their paths to becoming $100 billion corporations are ripe with competition, ranging from giants with vast resources to agile upstarts eager to disrupt the status quo.
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 huge upside potential and two that could be down big.
Two Mid-Cap Stocks to Sell:
Somnigroup (SGI)
Market Cap: $13.62 billion
Established through the merger of Tempur-Pedic and Sealy in 2012, Somnigroup (NYSE: SGI) is a bedding manufacturer known for its innovative memory foam mattresses and sleep products
Why Do We Think SGI Will Underperform?
- Annual revenue growth of 11.6% over the last five years was below our standards for the consumer discretionary sector
- Free cash flow margin is not anticipated to grow over the next year
- Waning returns on capital from an already weak starting point displays the inefficacy of management’s past and current investment decisions
Somnigroup’s stock price of $64.25 implies a valuation ratio of 19.8x forward P/E. Check out our free in-depth research report to learn more about why SGI doesn’t pass our bar.
Donaldson (DCI)
Market Cap: $10.54 billion
Playing a vital role in the historic Apollo 11 mission, Donaldson (NYSE: DCI) manufacturers and sells filtration equipment for various industries.
Why Are We Hesitant About DCI?
- Annual revenue growth of 4.1% over the last two years was below our standards for the industrials sector
- Weak constant currency growth over the past two years indicates challenges in maintaining its market share
- Diminishing returns on capital suggest its earlier profit pools are drying up
At $90.23 per share, Donaldson trades at 21.3x forward P/E. If you’re considering DCI for your portfolio, see our FREE research report to learn more.
