3 Mid-Cap Stocks with Questionable Fundamentals

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.

This is precisely where StockStory comes in - we do the heavy lifting to identify companies with solid fundamentals so you can invest with confidence. That said, here are three mid-cap stocks to avoid and some other investments you should consider instead.

Bentley Systems (BSY)

Market Cap: $12.13 billion

Pioneering the concept of "digital twins" for infrastructure projects long before it became an industry buzzword, Bentley Systems (NASDAQ:BSY) provides software solutions that help engineers design, build, and operate infrastructure projects across sectors including roads, bridges, utilities, mining, and industrial facilities.

Why Does BSY Worry Us?

1. Customers had second thoughts about committing to its platform over the last year as its average billings growth of 10.9% underwhelmed
2. Projected sales growth of 9.8% for the next 12 months suggests sluggish demand
3. Operating profits and efficiency rose over the last year as it benefited from some fixed cost leverage

At $38.59 per share, Bentley Systems trades at 8.1x forward price-to-sales. If you’re considering BSY for your portfolio, see our FREE research report to learn more.

Yum China (YUMC)

Market Cap: $17.17 billion

One of China’s largest restaurant companies, Yum China (NYSE:YUMC) is an independent entity spun off from Yum! Brands in 2016.

Why Are We Hesitant About YUMC?

1. Poor same-store sales performance over the past two years indicates it’s having trouble bringing new diners into its restaurants
2. Gross margin of 20.1% is below its competitors, leaving less money for marketing and promotions
3. Earnings per share lagged its peers over the last six years as they only grew by 5.5% annually

Yum China is trading at $48.51 per share, or 17.4x forward P/E. To fully understand why you should be careful with YUMC, check out our full research report (it’s free).

Clean Harbors (CLH)

Market Cap: $13.91 billion

Established in 1980, Clean Harbors (NYSE:CLH) provides environmental and industrial services like hazardous and non-hazardous waste disposal and emergency spill cleanups.

Why Are We Wary of CLH?

1. Organic sales performance over the past two years indicates the company may need to make strategic adjustments or rely on M&A to catalyze faster growth
2. Estimated sales growth of 3.3% for the next 12 months implies demand will slow from its two-year trend
3. Earnings per share lagged its peers over the last two years as they only grew by 5% annually

Clean Harbors’s stock price of $259.82 implies a valuation ratio of 33.2x forward P/E. Read our free research report to see why you should think twice about including CLH in your portfolio.
