This underperformance is further highlighted by the stock's negative returns over the past month and year, while the Sensex has shown positive returns in those periods. Although there has been a significant increase in investor participation, with delivery volume rising by 599.76% against the 5-day average, the overall market sentiment appears to be unfavorable, contributing to the stock's recent decline.
