The stock has recently hit a new 52-week high of Rs 4,346.2 but has underperformed its sector by 10.59% today, following a trend reversal after six consecutive days of gains. Despite this decline, the stock has shown impressive returns over various periods, including a 192.23% increase year-to-date and a 496.03% rise over the past three years. Positive factors contributing to its performance include strong long-term growth in net sales and operating profit, as well as increased participation from institutional investors, which indicates confidence in the company's fundamentals.

However, the stock's recent decline today contrasts with its overall positive trajectory and the sector's gain of 5.73%. The liquidity of the stock remains healthy, with a notable increase in delivery volume, suggesting ongoing interest from investors despite the current price drop.
