"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.

Finding the right balance between price and quality can challenge even the most skilled investors. Luckily for you, we started StockStory to help you identify the real opportunities. Keeping that in mind, here are two high-flying stocks expanding their competitive advantages and one where the price is not right.

One High-Flying Stock to Sell:

Myriad Genetics (MYGN)

Forward P/E Ratio: 68.5x

Founded in 1991 as one of the pioneers in translating genetic discoveries into clinical applications, Myriad Genetics (NASDAQ: MYGN) develops genetic tests that assess disease risk, guide treatment decisions, and provide insights across oncology, women's health, and mental health.

Why Should You Sell MYGN?

1. Muted 4.6% annual revenue growth over the last two years shows its demand lagged behind its healthcare peers
2. Negative returns on capital show management lost money while trying to expand the business, and its decreasing returns suggest its historical profit centers are aging
3. Diminishing returns on capital from an already low starting point show that neither management’s prior nor current bets are going as planned

Myriad Genetics’s stock price of $4.59 implies a valuation ratio of 68.5x forward P/E. Read our free research report to see why you should think twice about including MYGN in your portfolio.

Two High-Flying Stocks to Watch:

Apple (AAPL)

Forward P/E Ratio: 29.1x

Creator of the iPhone and App Store, Apple (NASDAQ: AAPL) is a legendary developer of consumer electronics and software.

Why Do We Watch AAPL?

1. Apple's revenue base is so large because nearly everyone in the U.S. has an iPhone, but this is a double-edged sword. Growth must now come from upgrades, a harder pitch that has resulted in sluggish top-line performance recently.
2. Still, Apple's devices have endured for decades, speaking to its brand, design ethos, and technological chops. Its success is rare in the world of consumer electronics, which is fraught because of commoditization, competition, and obsolescence risk.
3. The company may not have the best gross margin because of its hardware orientation, but it still manages to produce elite operating and free cash flow margins. This shows it doesn’t need over-the-top marketing campaigns to convince people to buy its products.

At $252.50 per share, Apple trades at 29.1x forward price-to-earnings. Is now the time to initiate a position? Find out in our full research report, it’s free.

Corning (GLW)

Forward P/E Ratio: 41.4x

Supplying windows for some of the United States’s earliest spacecraft, Corning (NYSE: GLW) provides glass and other electronic components for the consumer electronics, telecommunications, automotive, and healthcare industries.

Why Should GLW Be on Your Watchlist?

1. Annual revenue growth of 9.9% over the last two years beat the sector average and underscores the unique value of its offerings
2. Exciting sales outlook for the upcoming 12 months calls for 15.7% growth, an acceleration from its two-year trend
3. Earnings per share grew by 22% annually over the last two years, massively outpacing its peers

Corning is trading at $131.57 per share, or 41.4x forward P/E. Is now the right time to buy? See for yourself in our comprehensive research report, it’s free.
