Economic Moat
Evidence of durable competitive advantage in the filed financials (10 years of history).
Profit margins and economic moats, explainedThe filed history looks like a business competitors struggle to attack: high and steady margins, revenue that grows through cycles, and strong returns on capital.
55.5% average over the last 3 years
±1.1 pts around 55.7% across 10 years
grew in 9 of the last 9 year-over-year periods
positive in 10 of 10 years
15.0% latest fiscal year
A moat can't be proven by numbers alone — this scores the evidence a durable advantage leaves behind (pricing power, consistency, returns on capital), computed the same way for every stock. Pair it with the business overview before concluding anything.
Technical Analysis (Educational)
Technical analysis reads price and volume to judge momentum and timing. It complements the fundamentals above — it does not replace them. Here is what MPWR's chart says today, with each tool explained.
Trend — moving averages. A moving average is the average closing price over a window, which smooths out daily noise. MPWR trades near $1,221.16, around its 50-day average ($1,542.35) and 200-day average ($1,169.20). Price tangled in its moving averages means there is no clear trend — the stock is ranging.
Momentum — RSI. The Relative Strength Index runs 0–100 and measures how strong recent gains are versus losses. Above 70 is "overbought", below 30 "oversold". At 32 it is in neutral territory — neither stretched nor washed out.
MACD. MACD compares two moving averages to flag shifts in momentum. Its histogram is currently negative — short-term momentum is fading.
Volatility — ATR. Average True Range is the typical daily move. MPWR's is $100.67 (~8.2% of price), so swings of about that size each day are normal — handy for setting a stop that isn't too tight.
Support & resistance. In the month to Jul 6, 2026, MPWR found buyers near $1,258.66 (support) and sellers near $1,666.69 (resistance); its 52-week range then was $686.87–$1,714.09. A decisive break beyond either edge often marks the next move.
Volume. The latest session traded 1.0× the 20-day average — about normal. Rising volume on up-days suggests real buying; on down-days, real selling.

Educational scenario model, not a forecast or investment advice. It starts from the latest annual revenue in SEC filings. By default, growth is trailing revenue growth (held between 3% and 45% a year), the net margin is the latest one (held between 3% and 50%, so a loss-making company is modeled with a small profit), and the Base case P/E runs from 60% to 100% of today's. Carrying recent growth forward five years can miss badly in either direction. Outputs are only as good as the assumptions.
Bull Case
The case for MPWR:
- Revenue is growing 23.9% a year, a sign of real demand.
- High net margins (23.0%) point to pricing power or efficiency.
- Strong return on equity (19.2%) shows capital is put to work well.
- A conservative balance sheet (debt/equity 0.0x) lowers risk.
Bear Case
The case against MPWR:
- A rich 91.4x earnings multiple prices in a lot of growth.
- Limited free cash flow at today's price.
Key Risks
Valuation risk — at 91.4x earnings, disappointing results could compress the multiple.
Market risk — sector rotation, the economic cycle, and broad sentiment move the stock regardless of fundamentals.
Investment Thesis
On balance, the picture is mixed: Monolithic Power Systems is a large-cap information technology business still growing nicely, with solid profitability, and a sound balance sheet. It trades at 91.4x earnings, which our model scores Neutral (54/100). Weigh this against your own goals and time horizon — this is educational information, not a recommendation.

How is the 5-year projection for MPWR calculated?
It's a scenario model. It starts from the latest annual revenue and net margin in SEC filings, grows revenue at an assumed rate (trailing revenue growth by default), and applies a P/E range built around today's multiple to show the resulting share-price range.
