ON vs MPWR vs ENTG vs POWI vs AMAT

For growth investors, Monolithic Power Systems, Inc.

(MPWR) is the stronger pick with 26. 4% revenue growth year-over-year, versus -15. 3% for ON Semiconductor Corporation (ON). Applied Materials, Inc. (AMAT) offers the better valuation at 50. 3x trailing P/E (39. 3x forward), making it the more compelling value choice. Analysts rate ON Semiconductor Corporation (ON) a "Buy" — based on 46 analyst ratings — the highest consensus in this comparison.

On trailing P/E, Applied Materials, Inc.

(AMAT) is the cheapest at 50. 3x versus ON Semiconductor Corporation at 355. 9x. On forward P/E, ON Semiconductor Corporation is actually cheaper at 33. 7x — notably different from the trailing picture, reflecting expected earnings growth. The PEG ratio (P/E divided by earnings growth rate) is the most growth-adjusted single valuation metric: Monolithic Power Systems, Inc. wins at 2. 28x versus Applied Materials, Inc. 's 2. 29x.

Over the past 5 years, Monolithic Power Systems, Inc.

(MPWR) delivered a total return of +404. 2%, compared to -1. 3% for Power Integrations, Inc. (POWI). Over 10 years, the gap is even starker: MPWR returned +25. 3% versus POWI's +239. 0%. Past returns do not guarantee future results, and the stock with the higher historical return may already have its best growth priced in.

By beta (market sensitivity over 5 years), ON Semiconductor Corporation (ON) is the lower-risk stock at 1.

91β versus Entegris, Inc. 's 2. 73β — meaning ENTG is approximately 43% more volatile than ON relative to the S&P 500. On balance sheet safety, Monolithic Power Systems, Inc. (MPWR) carries a lower debt/equity ratio of 1% versus 98% for Entegris, Inc. — giving it more financial flexibility in a downturn.

By revenue growth (latest reported year), Monolithic Power Systems, Inc.

(MPWR) is pulling ahead at 26. 4% versus -15. 3% for ON Semiconductor Corporation (ON). On earnings-per-share growth, the picture is similar: Applied Materials, Inc. grew EPS 0. 6% year-over-year, compared to -92. 0% for ON Semiconductor Corporation. Over a 3-year CAGR, MPWR leads at 15. 9% annualised revenue growth. Higher growth typically commands a higher valuation multiple — check whether the premium P/E or P/S is justified by the growth rate using the PEG ratio.

The PEG ratio (forward P/E divided by expected earnings growth rate) is the most precise measure of undervaluation relative to growth potential.

By this metric, Monolithic Power Systems, Inc. (MPWR) is the more undervalued stock at a PEG of 2. 28x versus Applied Materials, Inc. 's 2. 29x. Both stocks trade at elevated growth-adjusted valuations, so expected growth needs to materialise. On forward earnings alone, ON Semiconductor Corporation (ON) trades at 33. 7x forward P/E versus 67. 2x for Monolithic Power Systems, Inc. — 33. 6x cheaper on a one-year earnings basis. Analyst consensus price targets imply the most upside for POWI: 7. 8% to $79. 00.

In this comparison, POWI (1.

1% yield), AMAT (0. 4% yield), MPWR (0. 4% yield), ENTG (0. 3% yield) pay a dividend. ON does not pay a meaningful dividend and should not be held primarily for income.

Applied Materials, Inc. (AMAT) carries a higher beta of 2. 19 — meaning larger drawdowns in market downturns, which matters significantly when you cannot wait years for a recovery. Both have compounded well over 10 years (ON: +1033%, AMAT: +21. 4%), confirming both are viable long-term holds — but the lower-volatility option typically results in less emotional selling during corrections. Retirement portfolios generally favour predictability over maximum returns. Consult a financial advisor before making allocation decisions.

Both stocks operate in the Technology sector, making this a peer-level intra-sector comparison — the same macro tailwinds and headwinds will affect both.

In terms of investment character: ON is a mid-cap quality compounder stock; MPWR is a mid-cap high-growth stock; ENTG is a mid-cap quality compounder stock; POWI is a small-cap quality compounder stock; AMAT is a large-cap quality compounder stock. POWI pays a dividend while ON, MPWR, ENTG, AMAT do not, making them suitable for different income and tax situations. These fundamental differences mean investors should not choose between them on a single metric — the "better stock" depends entirely on which of these characteristics aligns with your investment strategy.
