This session examines the critical intersection between wholesaler ordering behavior and pharmaceutical market forecasting. Attendees will gain practical insights into reconciling weekly order patterns with monthly gross factory sales, optimizing launch forecasts, and interpreting intra-monthly sales dynamics. Steven shares actionable frameworks for distinguishing true market demand from inventory build, enabling more accurate forecasting and supply planning. The presentation introduces advanced methodologies for analyzing wholesaler purchase data, identifying seasonal and speculative buying patterns, and integrating multiple data sources into predictive models. Special emphasis is placed on managing the disconnect between wholesaler orders and end-user consumption—particularly during launches, patent expirations, and market disruptions. Attendees leave equipped with diagnostic tools and early warning systems to improve forecast accuracy and reduce supply chain costs.
