Product Segmentation: Group products by their volatility index to understand which market segments are most sensitive to change.
Pricing Strategy Audit: Assess the effectiveness of promotional campaigns by observing the seven-day rebound or stabilization after an initial price change.
Risk Assessment: Use the change percentage as a risk indicator for inventory management or investment decisions.
