PEG Ratio

The current PEG ratio of 8.25x means that for each percentage point of expected earnings growth, investors are paying $8.25 per share of stock, which—unlike the simpler P/E ratio—factors in the company’s projected profit growth rate.

This level places KLAC far above its sector, where the median PEG ratio is 1.63x, and it ranks at the 100th percentile among its TECHNOLOGY peers, indicating it is the most expensively valued on this basis. The metric has been increasing sharply: although year-over-year data are not available, the quarter-over-quarter change is +1,131.3%, moving from 0.74x and 0.67x two and three quarters ago to 8.25x now. A high PEG ratio combined with a rapidly rising trend suggests that the stock’s price has far outpaced any improvement in expected growth, which may imply elevated downside risk if growth forecasts fail to materialize. This metric strongly contradicts the overall NEUTRAL verdict, as an extreme PEG ratio at the 100th percentile with an accelerating upward trend typically signals overvaluation rather than a balanced risk profile.
