Expensive stocks often command premium valuations because the market thinks their business models are exceptional. However, the downside is that high expectations are already baked into their prices, leaving little room for error if they stumble even slightly.

Determining whether a company’s quality justifies its price causes headaches for nearly all investors, which is why we started StockStory - to help you separate the real opportunities from the speculative ones. That said, here are two high-flying stocks with strong fundamentals and one climbing an uphill battle.

One High-Flying Stock to Sell:

PAR Technology (PAR)

Forward P/E Ratio: 87.2x

Originally founded in 1968 as a defense contractor for the U.S. government, PAR Technology (NYSE: PAR) provides cloud-based software, payment processing, and hardware solutions that help restaurants manage everything from point-of-sale to customer loyalty programs.

Why Does PAR Give Us Pause?

1. Cash-burning history makes us doubt the long-term viability of its business model
2. Negative returns on capital show management lost money while trying to expand the business

PAR Technology is trading at $34.00 per share, or 87.2x forward P/E. Check out our free in-depth research report to learn more about why PAR doesn’t pass our bar.

Two High-Flying Stocks to Watch:

CrowdStrike (CRWD)
