Why is Krishna Defence falling/rising?

As of 20-Oct, Krishna Defence & Allied Industries Ltd is currently priced at 789.25, reflecting an increase of 5.55, or 0.71%. The stock's performance today is in line with its sector, although it is experiencing a decline in investor participation, with delivery volume dropping by 38.42% compared to the 5-day average. The stock is trading higher than its 200-day moving average but lower than its 5-day, 20-day, 50-day, and 100-day moving averages. Over the past year, the stock has shown a positive return of 14.73%, significantly outperforming the Sensex, which has only increased by 3.98%. However, in the short term, the stock has seen a decline of 3.60% over the past week, indicating some recent weakness.
In the broader market context, the Sensex has gained 2.44% over the past week, contrasting with Krishna Defence's decline, suggesting that the stock is underperforming relative to the market. Year-to-date, while Krishna Defence has a modest gain of 1.10%, it still lags behind the Sensex's 9.30% increase. This underperformance in the short term, coupled with falling investor participation, may indicate a cautious sentiment among investors, despite the stock's strong long-term performance over three years, where it has surged by 671.51%.
