Sounds simple, right? Not always.
While the strategy may sound straightforward, it comes with risks. Misjudging value opportunities can lead to investing in value traps. These are stocks that seem attractive at first but continue to underperform because the issues pulling their prices down aren’t temporary.
That’s where the PEG ratio can be useful.
What is the PEG ratio?
The PEG ratio, or price/earnings to growth ratio, is a valuation metric that helps investors assess if a stock is undervalued or overvalued by considering both its current earnings and its expected future growth.
It builds upon the traditional P/E ratio by incorporating the company’s growth rate, making it particularly useful for comparing companies with different growth rates.
The PEG ratio is calculated by dividing a company’s P/E ratio by its earnings per share (EPS) growth rate.
A lower PEG ratio suggests that a stock may be undervalued, while a higher PEG ratio may indicate overvaluation.
A PEG ratio of 1 is often used as a benchmark, suggesting that a stock is fairly valued relative to its growth rate.
In this article, we will look at stocks with PEG ratios less than 1.

Conclusion
Low-PEG stocks attract investors because they combine the best of both worlds—reasonable valuations and strong earnings growth potential.
However, the PEG ratio has its limits. It doesn’t always capture shifts in growth rates, sector-specific risks, or external factors such as regulations and competition.
That’s why investors should treat it as one piece of a larger puzzle rather than the complete picture. Looking at it alongside metrics such as return on equity, cash flow, debt, and industry outlook gives a far more reliable view.
Happy investing!
