MPWR's exceptional balance sheet and liquidity (score: 95) provide a solid financial foundation, but the weak catalyst score (25) driven by heavy CEO insider selling (~$39.7M, zero buys) significantly undermines…

Factor checklist — research, not advice
A check leans with a bullish reading. A cross leans against it. A dash is unavailable or mixed.
- Insider Pulls against a bullish reading. Selling cluster — sale value, no purchase value
- Congress Pulls against a bullish reading. STOCK Act sale disclosures outnumber purchases
- Narrative Pulls against a bullish reading. Stored narrative reading is in the bearish band
- Timing Supports a bullish reading. Interesting trend — weekly bias up
- Financial indicators Supports a bullish reading. Current ratio 5.91 · operating margin 26%
Suggested stop 1377.61, nearest stored support minus 0.5 ATR(6.5% under the last close). Reward/risk to the next stored resistance is 0.98. Wait — that reward/risk is under 2. Research, not advice. Not an order.
