Institutional ownership collapsed 45.5 percentage points in Q4'25 — the quarter MPWR delivered record revenue of $751.2 million. When the smart money races for the exits during peak performance, the question isn't whether something's wrong, but what they see that the 100% bullish analyst chorus doesn't.
The business executes with Swiss watch precision — 38 earnings beats in 39 quarters isn't luck, it's operational excellence
97.4% beat rate over 10 years with 26.4% revenue growth and 26.6% operating margins in Q4'25.
Management's 20-quarter selling streak signals their own assessment of value
Insiders have been net sellers for 20 consecutive quarters while delivering perfect execution — they know what their labor is worth.
At 0.39% earnings yield versus 4.33% treasuries, the math violates every value principle
Paying 64.6x earnings when risk-free assets yield 11x more — a -3.94% spread that no amount of growth assumptions can reconcile.
Is perfect execution at the wrong price still investable?
Great companies deserve premium valuations, especially with 26.4% growth and fortress balance sheet
Fast grower with simple story, $1.1B cash, zero debt, and consistent execution — worth waiting for a better entry at 2.4x PEG.
No business quality can overcome paying 64.6x earnings in a 4.33% treasury world

The pendulum has swung — smart money exits at peak euphoria
Universal analyst bullishness, metrics at historical peaks, and massive institutional flight despite record results — classic top formation.
Operational excellence remains intact regardless of ownership shifts
Business fundamentals haven't changed — 26.4% growth, expanding margins, and the same execution machine that's delivered for a decade.
Four of five legends lean bearish, creating dangerous consensus that the valuation story dominates. But MPWR's unusual positive correlation with rates (0.712) and counter-cyclical demand (-0.887 consumer sentiment correlation) suggest this isn't a typical growth stock vulnerable to typical growth stock risks.
All five frameworks miss MPWR's geopolitical concentration risk — 55.3% of revenue from China with 94.4% product concentration in DC-to-DC converters. The business that thrives on global supply chain complexity could be its biggest vulnerability if trade tensions escalate. No framework adequately prices the binary risk of losing half your revenue overnight.
If institutions dumped 45.5 percentage points of ownership the same quarter MPWR hit record revenue of $751.2 million, what do they know about 2026 that the 100% bullish analyst consensus doesn't?
