Growth is oxygen. But when it evaporates, the consequences can be severe - ask anyone who bought Cisco in the Dot-Com Bubble or newer investors who lived through the 2020 to 2022 COVID cycle.
Luckily for you, our job at StockStory is to help you avoid short-term fads by pointing you toward high-quality businesses that can generate sustainable long-term growth. Keeping that in mind, here is one growth stock expanding its competitive advantage and two whose momentum may slow.
Two Growth Stocks to Sell:
Amplitude (AMPL)
One-Year Revenue Growth: +18.3%
Born from the realization that companies were flying blind when it came to understanding user behavior in their digital products, Amplitude (NASDAQ:AMPL) provides a digital analytics platform that helps businesses understand how people use their digital products to improve user experiences and drive revenue growth.
Why Do We Think Twice About AMPL?
- Struggled to drive increased usage of its software, demonstrated by its subpar 104% net revenue retention rate
- Poor expense management has led to operating margin losses
- Low free cash flow margin of 6.7% for the last year gives it little breathing room, constraining its ability to self-fund growth or return capital to shareholders
At $11.60 per share, Amplitude trades at 3.7x forward price-to-sales. Read our free research report to see why you should think twice about including AMPL in your portfolio.
RadNet (RDNT)
One-Year Revenue Growth: +18.9%
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 Are We Hesitant About RDNT?
- Incremental sales over the last five years were much less profitable as its earnings per share fell by 7.8% annually while its revenue grew
- Ability to fund investments or reward shareholders with increased buybacks or dividends is restricted by its weak free cash flow margin of 1.9% for the last five years
- ROIC of 5.7% reflects management’s challenges in identifying attractive investment opportunities, and its falling returns suggest its earlier profit pools are drying up
RadNet’s stock price of $70.56 implies a valuation ratio of 104.6x forward P/E. Dive into our free research report to see why there are better opportunities than RDNT.
One Growth Stock to Watch:
Cactus (WHD)
One-Year Revenue Growth: +21.8%
Named for the spiky wellhead equipment that reminded founders of desert cacti, Cactus (NYSE:WHD) manufactures wellheads, valves, and spoolable pipes used in drilling and producing oil and gas wells.
Why Do We Like WHD?
- Annual revenue growth of 28.5% over the last ten years was superb and indicates its market share increased during this cycle
- EBITDA margin failed to increase over the last five years, indicating the company couldn’t optimize its expenses
- Robust free cash flow margin of 21.7% gives it many options for capital deployment
Cactus is trading at $69.84 per share, or 22x forward P/E. Is now a good time to buy? See for yourself in our comprehensive research report, it’s free.
