"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 three high-flying stocks with strong fundamentals.

2. Performance over the past two years shows its incremental sales were extremely profitable, as its annual earnings per share growth of 30.8% outpaced its revenue gains
3. Robust free cash flow margin of 19.7% gives it many options for capital deployment, and its improved cash conversion implies it’s becoming a less capital-intensive business
