1 Mid-Cap Stock to Target This Week and 2 We Find Risky

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 best left ignored.

Two Mid-Cap Stocks to Sell:

Donaldson (DCI)

Market Cap: $10.62 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 Cautious About DCI?

1. Core business is underperforming as its organic revenue has disappointed over the past two years, suggesting it might need acquisitions to stimulate growth
2. Anticipated sales growth of 4.3% for the next year implies demand will be shaky
3. Diminishing returns on capital suggest its earlier profit pools are drying up

At $91.79 per share, Donaldson trades at 2.8x forward price-to-sales. Read our free research report to see why you should think twice about including DCI in your portfolio.

Penske Automotive Group (PAG)

Market Cap: $10.37 billion

With a diverse global network spanning the US, UK, Canada, Germany, Italy, Japan, and Australia, Penske Automotive Group (NYSE:PAG) operates automotive and commercial truck dealerships across the globe, selling new and used vehicles while providing service, parts, and financing options.

Why Do We Think PAG Will Underperform?

1. Weak same-store sales trends over the past two years suggest there may be few opportunities in its core markets to open new locations
2. Commoditized inventory, bad unit economics, and high competition are reflected in its low gross margin of 13%
3. Incremental sales over the last three years were much less profitable as its earnings per share fell by 10.5% annually while its revenue grew

Penske Automotive Group’s stock price of $157.69 implies a valuation ratio of 11.7x forward P/E. If you’re considering PAG for your portfolio, see our FREE research report to learn more.

One Mid-Cap Stock to Buy:

Erie Indemnity (ERIE)

Market Cap: $14.1 billion

Operating under a unique business model dating back to 1925, Erie Indemnity (NASDAQ:ERIE) serves as the attorney-in-fact for Erie Insurance Exchange, managing policy issuance, claims handling, and investment services for this reciprocal insurer.

Why Do We Love ERIE?

1. Market share has increased this cycle as its 11.5% annual revenue growth over the last two years was exceptional
2. Balance sheet strength has increased this cycle as its 14% annual book value per share growth over the last five years was exceptional
3. Stellar return on equity showcases management’s ability to surface highly profitable business ventures

Erie Indemnity is trading at $273.83 per share, or 20.1x forward P/E. Is now the time to initiate a position? See for yourself in our comprehensive research report, it’s free.
