The stocks featured in this article have all approached their 52-week highs. When these price levels hit, it typically signals strong business execution, positive market sentiment, or significant industry tailwinds.
But not every company with momentum is a long-term winner, and plenty of investors have lost money betting on short-term fads. On that note, here are three stocks that are likely overheated and some you should look into instead.
Tenable (TENB)
One-Month Return: +18.6%
Starting with the widely-used Nessus vulnerability scanner first released in 1998, Tenable (NASDAQ: TENB) provides exposure management solutions that help organizations identify, assess, and prioritize cybersecurity vulnerabilities across their IT infrastructure and cloud environments.
Why Does TENB Worry Us?
- Offerings struggled to generate meaningful interest as its average billings growth of 7.1% over the last year did not impress
- Estimated sales growth of 6.9% for the next 12 months implies demand will slow from its two-year trend
- Operating margin improvement of 5.1 percentage points over the last year demonstrates its ability to scale efficiently
Tenable is trading at $41.60 per share, or 4.2x forward price-to-sales. Dive into our free research report to see why there are better opportunities than TENB.
Amplitude (AMPL)
One-Month Return: +14.3%
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 Are We Wary of AMPL?
- Net revenue retention rate of 104% trails the industry benchmark of 110%+ and shows it has a tough time increasing customer spending
- Poor expense management has led to operating margin losses
- Ability to fund investments or reward shareholders with increased buybacks or dividends is restricted by its weak free cash flow margin of 6.7% for the last year
Amplitude’s stock price of $15.61 implies a valuation ratio of 4.5x forward price-to-sales. Read our free research report to see why you should think twice about including AMPL in your portfolio.
Revvity (RVTY)
One-Month Return: +20.1%
Formerly known as PerkinElmer until its rebranding in 2023, Revvity (NYSE: RVTY) provides health science technologies and services that support the complete workflow from discovery to development and diagnosis to cure.
Why Do We Avoid RVTY?
- Annual sales declines of 10.6% for the past five years show its products and services struggled to connect with the market during this cycle
- Absence of organic revenue growth over the past two years suggests it may have to lean into acquisitions to drive its expansion
- Earnings per share decreased by more than its revenue over the last five years, showing each sale was less profitable
At $154.38 per share, Revvity trades at 27.6x forward P/E. Check out our free in-depth research report to learn more about why RVTY doesn’t pass our bar.
