"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 is one high-flying stock to hold for the long term and two with big downside risk.

Two High-Flying Stocks to Sell:

Tesla (TSLA)

Forward P/E Ratio: 124.6x

Originally founded by Martin Eberhard and Marc Tarpenning in 2003, Tesla (NASDAQ: TSLA) is an electric vehicle company accelerating the world’s transition to sustainable energy.

Why Is TSLA Not Exciting?

1. Tesla's scale advantage in EV production leads to gross margins that exceed incumbents such as General Motors and Ford. However, a softer macroeconomic backdrop and tariff pressures have weighed on automobile sales, which are highly cyclical.
2. The company's execution ability is a question mark given its long history of delays, such as the Cybertruck and Robotaxi launches. Its sizeable investments in projects with uncertain return timelines, like Optimus, also raise skepticism from investors.
3. On the bright side, Tesla's Megapack product solves a critical problem for utilities needing renewable energy storage solutions. This innovation has made the energy segment the most profitable and fastest-growing business line for the company.

Tesla is trading at $326.92 per share, or 124.6x forward price-to-earnings. Dive into our free research report to see why there are better opportunities than TSLA.

RadNet (RDNT)

Forward P/E Ratio: 104.7x

With over 350 imaging facilities across seven states and a growing artificial intelligence division, RadNet (NASDAQ: RDNT) operates a network of outpatient diagnostic imaging centers across the United States, offering services like MRI, CT scans, PET scans, mammography, and X-rays.

Why Does RDNT Give Us Pause?

1. Smaller revenue base of $1.87 billion means it hasn’t achieved the economies of scale that some industry juggernauts enjoy
2. Capital intensity has ramped up over the last five years as its free cash flow margin decreased by 3.9 percentage points
3. Low returns on capital reflect management’s struggle to allocate funds effectively

RadNet’s stock price of $55.30 implies a valuation ratio of 104.7x forward P/E. If you’re considering RDNT for your portfolio, see our FREE research report to learn more.

One High-Flying Stock to Buy:

Nvidia (NVDA)

Forward P/E Ratio: 30.1x

Founded in 1993 by Jensen Huang and two former Sun Microsystems engineers, Nvidia (NASDAQ: NVDA) is a leading fabless designer of chips used in gaming, PCs, data centers, automotive, and a variety of end markets.

Why Is NVDA a Good Business?

1. Impressive 140% annual revenue growth over the last two years indicates it’s winning market share this cycle
2. Share repurchases over the last five years enabled its annual earnings per share growth of 80.2% to outpace its revenue gains
3. Impressive free cash flow profitability enables the company to fund new investments or reward investors with share buybacks/dividends, and its improved cash conversion implies it’s becoming a less capital-intensive business

At $141.80 per share, Nvidia trades at 30.1x forward P/E. Is now a good time to buy? Find out in our full research report, it’s free.
