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 $1,537.88, around its 50-day average ($1,546.42) and 200-day average ($1,145.10). 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 50 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 $112.82 (~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 $1,405.00 (support) and sellers near $1,714.09 (resistance); its 52-week range is $671.18–$1,714.09. A decisive break beyond either edge often marks the next move.
Volume. The latest session traded 2.3× the 20-day average — heavier than usual, which adds conviction to the move. 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 117.0x earnings multiple prices in a lot of growth.
- Limited free cash flow at today's price.
Valuation risk — at 117.0x earnings, disappointing results could compress the multiple.
Market risk — sector rotation, the economic cycle, and broad sentiment move the stock regardless of fundamentals.
