High YoY From Weak Base Masks Sequential Stall — QoQ Is the Real Diagnostic

When a company reports high YoY growth (>50%) but near-zero QoQ sequential growth (<5%), the YoY is likely flattered by a weak prior-year comparable rather than reflecting genuine business momentum. Investors anchoring on the headline YoY will miss that the company has plateaued. The QoQ number is the unambiguous signal: it has no base-period distortion and reflects current momentum directly.

Evidence

• FIGR Q4 FY25: 90.8% YoY growth headlines look exceptional. But Q4 FY24 was $84m — a weak base. Q4 FY25 revenue of 160monthatbaseinflatestheYoY.QoQwasonly2.3156m → $160m), meaning the company was essentially flat sequentially. Operating margin simultaneously compressed from 33.7% → 18.1%. WSM analysis flagged immediately: "The QoQ tells the real story." One-quarter ultimatum set: if Q1 FY26 doesn't reaccelerate, sell.

Implication

When screening for deceleration or stall signals, always read YoY alongside QoQ. If YoY is high (>50%) but QoQ is near-zero (<5%), investigate the prior-year base period: IPO quarter, product transition, one-time disruption, or prior-year miss. Any of these produce an artificially low base that flatters the current YoY. In these cases, treat QoQ as the primary signal and YoY as noise — the opposite of the typical weighting. Flag as a stall candidate and set a one-quarter proof window before sizing up.
