Operating margins swung from -21.7% to 31.9% in 10 quarters while insiders dumped record shares at the peak.

Western Digital demonstrates classic late-cycle extremes — seven profitability metrics at 10-year highs while insiders execute their heaviest selling on record.

Is the price above or below what the business is worth?

This framework sees a business priced for perfection despite cyclical vulnerabilities. The market expects growth to double from current levels — a bet that storage demand will accelerate indefinitely. At 18,992% above intrinsic value, the margin of safety has inverted into a margin of speculation.

Where are we in the cycle?

The pendulum has swung to an extreme rarely seen — from the deepest trough to the highest peak in just 10 quarters. When seven metrics hit decade highs simultaneously, the cycle is extended beyond normal bounds. History suggests such extremes don't persist.

Where might consensus be wrong?

First-level thinking sees record margins and declares victory. Second-level thinking asks why insiders are selling most aggressively at the moment of greatest operational success. The consensus celebrates the recovery without questioning its sustainability.

Does upside significantly exceed downside?

The asymmetry tilts unfavorably — limited upside from already-peak margins versus substantial downside if the cycle turns. With 4.5x operating leverage, any revenue deceleration will savage profitability. The best-case scenario is already priced in.

Applying this framework reveals a classic late-cycle setup — operational metrics at extremes, insiders heading for exits, and prices that assume the best continues forever. The 53.6 percentage point margin swing from trough to peak in 10 quarters reminds us that what goes up fast can fall faster. When the CFO sells at the profit peak, should outside investors be buying?
