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.

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:

Zillow (ZG)

Forward P/E Ratio: 35.9x

Founded by Expedia co-founders Lloyd Frink and Rich Barton, Zillow (NASDAQ: ZG) is the leading U.S. online real estate marketplace.

Why Are We Out on ZG?

1. Products and services have few die-hard fans as sales have declined by 7.6% annually over the last five years
2. Suboptimal cost structure is highlighted by its history of operating margin losses
3. Eroding returns on capital from an already low base indicate that management’s recent investments are destroying value

Zillow’s stock price of $67.36 implies a valuation ratio of 35.9x forward P/E. If you’re considering ZG for your portfolio, see our FREE research report to learn more.

Two High-Flying Stocks to Watch:

Roblox (RBLX)

Forward EV/EBITDA Ratio: 62x

Best known for its wide assortment of user-generated content, Roblox (NYSE: RBLX) is an online gaming platform and game creation system.

Why Should RBLX Be on Your Watchlist?

1. Daily Active Users have increased by an average of 22.1% annually, giving it the potential for margin-accretive growth if it can develop valuable complementary products and features
2. Brand halo makes it a customer acquisition machine that onboards new users at scale without spending much money
3. Disciplined cost controls and effective management resulted in a strong two-year EBITDA margin of 20.5%

At $105.35 per share, Roblox trades at 62x forward EV/EBITDA. Is now the right time to buy? Find out in our full research report, it’s free.

e.l.f. Beauty (ELF)

Forward P/E Ratio: 34.8x

Short for "eyes, lips, face", e.l.f. Beauty (NYSE: ELF) is a developer of high-quality beauty products at accessible price points.

Why Is ELF on Our Radar?

1. Market share has increased over the last three years as its 49.6% annual revenue growth was exceptional
2. Products command premium prices and result in a best-in-class gross margin of 71%
3. Earnings growth has massively outpaced its peers over the last three years as its EPS has compounded at 58.6% annually
