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.
Luckily for you, our mission at StockStory is to help you make money and avoid losses by sorting the winners from the losers. Keeping that in mind, here are two mid-cap stocks with huge upside potential and one that could be down big.
One mid-cap stock to sell:
Align Technology (ALGN)
Market cap: $11.23 billion
Pioneering an alternative to traditional metal braces with nearly invisible plastic aligners, Align Technology (NASDAQ: ALGN) designs and manufactures Invisalign clear aligners, iTero intraoral scanners, and dental CAD/CAM software for orthodontic and restorative treatments.
Why Are We Cautious About ALGN?
- Muted 2.1% annual revenue growth over the last five years shows its demand lagged behind its healthcare peers
- Earnings per share were flat over the last five years and fell short of the peer group average
- Diminishing returns on capital suggest its earlier profit pools are drying up
Align Technology’s stock price of $159.46 implies a valuation ratio of 13.9x forward P/E. To fully understand why you should be careful with ALGN, check out our full research report (it’s free).
