Trade Engine

Sienna Whitaker spent twelve years advising brands on pricing and mix before moving to the markets desk, where she covers consumer staples and discretionary. At Trade Engine she focuses on basket inflation, elasticity, and channel shift, helping readers parse throughput, inventory health, and promotion cadence. Expect clear breakdowns of what same-store sales and traffic actually signal, how private label competes with legacy names, and which cohorts drive ticket size. Her analyses have been featured in retail conferences and trade publications, with frequent media guest spots during the holidays and back-to-school cycles. Sienna’s field work includes store walks and app-based user tests to validate claims made on earnings calls. Away from screens she is an avid home cook who tracks pantry inflation in her own kitchen, translating shelf checks into actionable context.
