Volume-Price Dynamics: While volume surged, delivery volumes declined, suggesting a mix of short-term trading and cautious accumulation by longer-term investors.

The stock’s ability to rally strongly on 20 May amid a subdued Sensex environment, coupled with a technical trend upgrade on 21 May, underscores its resilience and renewed investor focus. Despite a slight pullback on the final trading day, the overall weekly performance and technical indicators suggest a positive momentum foundation.
