Why is Krishna Defence falling/rising?

As of 22-Sep, Krishna Defence & Allied Industries Ltd is experiencing a price increase, with the current price at 819.35, reflecting a change of 9.8 or 1.21% upward. The stock has outperformed its sector by 1.9% today, although it is currently trading higher than its 20-day, 50-day, and 200-day moving averages, but lower than its 5-day and 100-day moving averages. Despite this positive movement, there has been a notable decline in investor participation, with delivery volume on 19 September falling by 43.17% compared to the 5-day average. The stock has shown a year-to-date return of 4.96%, which is lower than the benchmark Sensex's return of 6.59% during the same period.
In the broader market context, the stock's recent performance over the past week shows a decline of 4.07%, while the Sensex has gained 0.53%, indicating that Krishna Defence has underperformed relative to the benchmark in the short term. However, over the last month, the stock has increased by 2.65%, outperforming the Sensex's 1.34% gain. This suggests that while the stock has faced short-term challenges, its longer-term performance remains strong, particularly over the past year with a return of 12.56% compared to the Sensex's decline of 2.28%. Overall, the combination of positive price movement today and the stock's historical performance contrasts with the recent drop in investor participation, which may be a concern for future trading activity.
