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 is one high-flying stock with strong fundamentals and two climbing an uphill battle.

Two High-Flying Stocks to Sell:

Woodward (WWD)

Forward P/E Ratio: 35.7x

Initially designing controls for water wheels in the early 1900s, Woodward (NASDAQ: WWD) designs, services, and manufactures energy control products and optimization solutions.

Why Do We Think Twice About WWD?

2. Earnings growth underperformed the sector average over the last five years as its EPS grew by just 7.1% annually
3. 11.2 percentage point decline in its free cash flow margin over the last five years reflects the company’s increased investments to defend its market position
