"You get what you pay for" often applies to expensive stocks with best-in-class business models and execution. While their quality can sometimes justify the premium, they typically experience elevated volatility during market downturns when expectations change.

Separating true intrinsic value from speculation isn’t easy, especially during bull markets. That’s where StockStory comes in - to help you find high-quality companies that will stand the test of time. Keeping that in mind, here are two high-flying stocks expanding their competitive advantages and one climbing an uphill battle.

One High-Flying Stock to Sell:

Seadrill (SDRL)

Forward P/E Ratio: 199.5x

Operating in water depths reaching 12,000 feet below the surface, Seadrill (NYSE: SDRL) owns and operates drillships and semi-submersible rigs that drill oil and gas wells in deepwater offshore locations.

Why Is SDRL Risky?

1. Products and services are facing significant end-market challenges during this cycle as sales have declined by 10.5% annually over the last ten years
2. Gross margin of 34% reflects its high production costs and unfavorable asset base
3. Cash burn makes us question whether it can achieve sustainable long-term growth

At $46.14 per share, Seadrill trades at 199.5x forward P/E. Read our free research report to see why you should think twice about including SDRL in your portfolio.
