Is MPWR undervalued?

MPWR closed at 1,261.08 on 5 Nov 2026, more than 30% above the GLS average fair value of 467.50. Only 0 of the 9 models that produced a value sit above the price. By our models the shares are priced well beyond what the filed earnings, cash flow and book value support; the "below fair value" Wheel Trade Filter keeps names like this under 70.

The 9 models disagree widely: DDM gives 111.24 while GLS Growth gives 1,112.93. A spread that wide means the average is sensitive to which methods you trust; the model table below shows where each one lands, and the Quote page lets you switch any of them off.

Ranked against every other company we cover, MPWR is clearly faster-growing than it is cheap, so the nightly engine files it under Growth (value score 6, growth score 84, out of 100).

Nine valuation models for MPWR

Each model turns the latest filed numbers into a value per share; the GLS fair value is the simple average of the ones that produce a positive number. The last two rows are shown for reference and never enter the average. The Quote page lets you switch any model off and add your own margin of safety.

Quality and financial health

Financial health is average - MPWR passes 5 of the nine Piotroski tests, which falls one point short of the "Piotroski 6 or more" Wheel Trade Filter. The Financials tab on the Quote page shows which tests fail. The GLS Moat score is 8.7 out of 10 - high returns on capital, steady margins and growth that held up through bad years point to a durable business.

Returns on capital are high - ROIC 17.3%, ROE 17.4%, ROA 14.7% - with debt at 0.01 times equity and a free-cash-flow yield of 1.0%.

The dividend yield is 0.60% with a payout ratio of 40% - a small yield that leaves most of the earnings in the business. Revenue comes mainly from DC To DC Products 99%, Lighting Control Products 1% (quarter Q3 FY2024).

Institutional ownership scores 10/10, insider activity 1/10 and Congressional trading 1/10 on the GLS smart-money scales.

Wheel Score 41: Weak

MPWR scores 41 out of 100 on the Wheel Score, in the Weak band (under 50): it fails filter 3, below fair value - trades 170% above our fair value; and filter 4, financially healthy - Piotroski 5/9 (under 6), and the parts are thin too - value weak, premium strong, moat strong, health fair, red flags good, option trading fair, stability good. The score is not a judgement on the company; it says the price, quality and premium do not line up for selling puts on it today.

Implied volatility is 61% on the near-the-money contracts 20-60 days out - above the 60% top of the sweet spot. It still passes the 25-80% filter, but the Wheel Score rewards it less because volatility this high usually comes with a reason. Chain open interest is 10,763 contracts across all expiries - enough for the wheel at normal size.

Volume runs at 1.2M shares a day on a market cap of $61.5B, with a beta of 1.72 - a high beta, so the stock tends to move more than the market and a strike can be gapped through; the Stability part of the Wheel Score rates that good.
