Is MKS Instruments stock undervalued or overvalued?
Valuing MKS Instruments stock is incredibly difficult, and any metric has to be viewed as part of a bigger picture of MKS Instruments's overall performance. However, analysts commonly use some key metrics to help gauge the value of a stock.
MKS Instruments's P/E ratio
MKS Instruments's current share price divided by its per-share earnings (EPS) over a 12-month period gives a "trailing price/earnings ratio" of roughly 31x. In other words, MKS Instruments shares trade at around 31x recent earnings.
That's relatively high compared to, say, the trailing 12-month P/E ratio for the NASDAQ 100 at the end of 2019 (27.29). The high P/E ratio could mean that investors are optimistic about the outlook for the shares or simply that they're over-valued.
MKS Instruments's PEG ratio
MKS Instruments's "price/earnings-to-growth ratio" can be calculated by dividing its P/E ratio by its growth – to give 0.61. A low ratio can be interpreted as meaning the shares offer better value, while a higher ratio can be interpreted as meaning the shares offer worse value.
The PEG ratio provides a broader view than just the P/E ratio, as it gives more insight into MKS Instruments's future profitability. By accounting for growth, it could also help you if you're comparing the share prices of multiple high-growth companies.
MKS Instruments's EBITDA

MKS Instruments share dividends
Dividend payout ratio: 12.38% of net profits
Recently MKS Instruments has paid out, on average, around 0% of net profits as dividends. That has enabled analysts to estimate a "forward annual dividend yield" of 0% of the current stock value. This means that over a year, based on recent payouts (which are sadly no guarantee of future payouts), MKS Instruments shareholders could enjoy a 0% return on their shares, in the form of dividend payments. In MKS Instruments's case, that would currently equate to about $0.88 per share.
While MKS Instruments's payout ratio might seem low, this can signify that MKS Instruments is investing more in its future growth.
MKS Instruments's most recent dividend payout was on 5 June 2025. The latest dividend was paid out to all shareholders who bought their shares by 26 May 2025 (the "ex-dividend date").
MKS Instruments share price volatility
Over the last 12 months, MKS Instruments's shares have ranged in value from as little as $54.702 up to $131.9396. A popular way to gauge a stock's volatility is its "beta".
Beta is a measure of a share's volatility in relation to the market. The market (NASDAQ average) beta is 1, while MKS Instruments's is 1.833. This would suggest that MKS Instruments's shares are more volatile than the average for this exchange and represent, relatively-speaking, a higher risk (but potentially also market-beating returns).
