A stock can become overvalued when the price of a security becomes detached from its underlying fundamentals. In the short run, stocks can stray far from their intrinsic value, but in the long run, they will eventually move back closer to the true value of the underlying company.
Sometimes, this results in an opportunity to buy undervalued stocks, but it can also swing the other way. If you buy an overvalued stock, it will likely end up underperforming the market as the price eventually falls back to its real value.
Definition
What is an overvalued stock?
An overvalued stock is one that trades at a price significantly higher than its fundamental earnings and revenue outlooks suggest it should. It may also trade at a price-to-earnings (P/E) multiple higher than its peers when adjusted for future growth.

How to determine whether a stock is overvalued
You can use a variety of metrics to assess a stock's value. Two of the most common are the P/E ratio and the enterprise-value-to-EBITDA (earnings before interest, taxes, depreciation, and amortization) ratio, or EV/EBITDA. Both are measurements of the current stock price versus the underlying company's earnings or earnings potential.
It's also important to consider a company's future earnings growth. All else being equal, a fast-growing company absolutely should trade at a higher earnings multiple than a slow-growing company. Some investors look at the price/earnings-to-growth ratio (PEG ratio) as another indicator of whether a stock is overvalued.
The best way to determine whether a stock is overvalued is to dig into the company yourself. Make your own estimates for its future revenue growth, margin expansion (or compression), and how it all affects the bottom line. Sometimes, you might find something the rest of the market is missing.
The most overvalued
The most overvalued stocks
Here are three overvalued stocks:
Vistra
Vistra (VST 2.64%) has benefited greatly from the boom in artificial intelligence (AI) spending. As hyperscalers build out more and more massive data centers, Vistra has seen growing demand for its power generation capabilities. Vistra has inked several big deals while expanding its capacity.
Vistra is heavily focused on investing in zero-carbon power generation, which includes solar and nuclear. It’s also developing energy storage technology to use zero-emission power more effectively. Vistra gave its nuclear energy capacity a big boost in 2024 by acquiring Energy Harbor. That can help it serve more data center customers, as demand continues to boom.
But Vistra stock looks overvalued. Its enterprise value is roughly 11-times management’s expectations for 2025 EBITDA. That would be good value for a growth stock, but management’s guidance for EBITDA growth of single-digit percentage rate in 2026 doesn’t deserve such a high multiple. Comparable businesses trade for much lower multiples.
United Airlines
United Airlines (UAL -1.35%) stock took off in 2024 as travel demand climbed significantly faster than supply. United’s focus on more efficient planes and long-haul flights has benefited its margins amid soaring demand. That’s helped it fill more planes and generate greater revenue per flight. Still, operating margin remains below pre-COVID-19 pandemic levels, which averaged 11.3% from 2015 through 2019.
United faces a significant threat from a potential recession, which would curb leisure travel. Management said a recession would cut its earnings per share outlook for 2025 by roughly 35%. Meanwhile, competition increasing capacity could keep flight prices stable even if fuel costs continue to climb.
United’s stock value might look attractive at less than eight times forward earnings, but analysts are expecting negative earnings per share growth for the year. What’s more, that’s roughly in line with its historical average and the industry average. But United is spending heavily to update its fleet, leaving less capital for things like returning cash to shareholders. That makes it far less attractive than its peers.
Take Two Interactive
Take Two Interactive (TTWO -1.33%) is home to some of the biggest video game franchises in the industry: NBA 2K, Borderlands, and Mafia, just to name a few. But the biggest of them all is Grand Theft Auto. That’s why its stock fell significantly on news that GTA VI would be delayed six months until fiscal 2027 (May 2026).
GTA VI is anticipated to be one of the biggest video game releases of all time. As a result, investors have bid up the stock in anticipation. But that makes Take Two extremely risky, with its value based on a single release -- a release that already has high expectations built in. A shortfall (or another delay) could send the stock cratering.
The stock now trades for a forward price earnings ratio of 32. That’s far higher than competing game studios. If GTA VI doesn’t deliver, investors will see the stock price come down to earth.
