CONVERGENCE
WHERE 5 FRAMEWORKS LAND

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.

WHERE THEY AGREE

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.

Buffett · Lynch · Mauboussin

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.

Buffett · Marks · Graham

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.

WHERE THEY DISAGREE

Is perfect execution at the wrong price still investable?

LYNCH

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.

VS
GRAHAM · MARKS · MAUBOUSSIN

No business quality can overcome paying 64.6x earnings in a 4.33% treasury world

Negative ROIC-WACC spread of -6.73%, institutions fleeing down 45.5pp, and requiring 9.65% perpetual growth to justify current price.

Does the 45.5pp institutional exodus in Q4'25 mark the top or create opportunity?

MARKS

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.

VS
BUFFETT · LYNCH

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.

CONSENSUS RISKHIGH

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.

THE BLIND SPOT

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.

THE QUESTION

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?
