Evidence of durable competitive advantage in the filed financials (10 years of history).
The 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
16.0% 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 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 $1,383.15, 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 (~7.3% of price), so swings of about that size each day are normal — handy for setting a stop that isn't too tight.
Support & resistance. Over the last month MPWR found buyers near $1,258.66 (support) and sellers near $1,666.69 (resistance); its 52-week range is $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 model on sample fundamentals — not a forecast or investment advice. Outputs are only as good as your assumptions.
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.
The case against MPWR:
- A rich 103.5x earnings multiple prices in a lot of growth.
- Limited free cash flow at today's price.
Valuation risk — at 103.5x earnings, disappointing results could compress the multiple.
Market risk — sector rotation, the economic cycle, and broad sentiment move the stock regardless of fundamentals.
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 103.5x earnings, which our model scores Neutral (54/100). Weigh this against your own goals and time horizon — this is educational information, not a recommendation.
