The stock has recently experienced a trend reversal, gaining after five consecutive days of decline. However, it is trading below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating a bearish trend. Additionally, investor participation has decreased, with delivery volume falling by 15.8% compared to the 5-day average. Over the past week, the stock has underperformed the benchmark Sensex, declining by 4.58% while the Sensex increased by 1.58%. Year-to-date, the stock has a positive return of 7.70%, outperforming the Sensex's 5.43%.
In the broader market context, the stock's recent performance contrasts sharply with the benchmark, particularly in the short term, where it has seen a significant decline compared to the Sensex's gains. The stock's performance over the past month also shows a decline of 3.99%, while the Sensex rose by 2.21%. Despite a positive year-over-year return of 10.42%, the stock's longer-term performance over three and five years lags behind the benchmark, which has increased by 40.01% and 109.60%, respectively. This underperformance relative to the market may be contributing to the cautious sentiment among investors, reflected in the falling delivery volumes and overall liquidity.
