PEG Ratio

The PEG ratio combines the price-to-earnings (P/E) multiple with the company’s expected earnings growth rate, so a 2.30x PEG means investors are paying $2.30 for every 1% of projected annual earnings growth.

This ratio sits well above the sector median of 0.97x and places MPWR in the 76th percentile among its sector peers, indicating it is more expensive relative to growth than most comparable companies. Over the last eight quarters the PEG ratio has been decreasing, but the most recent quarter-over-quarter change shows a +5.5% increase from 2.18x to 2.30x; year-over-year data is not available. A high PEG ratio combined with a recent uptick suggests the stock remains richly valued versus its growth prospects, though the longer-term downward trend may point to gradual improvement in that valuation. This mix of elevated level and mixed trend introduces uncertainty, making it neither a clear opportunity nor a pronounced risk. Thus, the metric supports the overall NEUTRAL verdict because the valuation is not cheap enough to be a strong buy nor alarmingly high to warrant a sell.
