31.3% net margins can't justify 28x earnings for 2.4% growth — insiders selling while institutions pay fast grower prices for stalwart returns.
A cash-rich stalwart with monopoly-like margins trades at fast grower prices despite 2.4% growth and insiders heading for exits.
What kind of company is this and what should we expect?
This framework classifies CPRT as a stalwart masquerading as a fast grower. The 2.4% growth rate is classic stalwart territory, but the 31.3% margins and dominant market position give it fast grower characteristics without the growth.
Are we paying a fair price for the growth we're getting?
Applying this lens reveals extreme overvaluation — paying 28x earnings for 2.4% growth yields a PEG over 11x, far above Lynch's 1.0 threshold. The market prices this stalwart like a fast grower, creating significant downside risk.
Are insiders buying or selling with their own money?
This framework sees a clear signal — insiders have been net sellers for years. Lynch taught that insiders sell for many reasons but buy for only one, and CPRT insiders aren't buying despite the stock's 47.7% drawdown.
Can you explain in one sentence why this company grows?
The growth story is simple but limited: CPRT runs online auctions for salvage vehicles with pricing power tied to inflation. However, 2.4% growth reveals this story is mature, not exciting, making the 28x P/E inexplicable through this lens.
Applying this framework reveals a paradox: CPRT has the margins of a fast grower, the growth rate of a stalwart, and the valuation of a hot tech stock. The 31.3% net margins and dominant market position are exactly what Lynch sought, but paying 28x earnings for 2.4% growth violates his fundamental principle — the P/E should roughly equal the growth rate. With insiders consistently selling and $5.1 billion earning below treasury yields, this looks like a wonderful business at a terrible price. Would Lynch pay 11x PEG for any stock, no matter how good the business?
