Why is Shakti Pumps falling/rising?

As of 31-Jul, Shakti Pumps (India) Ltd is experiencing a decline in its stock price, currently at Rs 892.10, which reflects a decrease of Rs 12.9 or 1.43%. Today's price summary indicates that the stock has underperformed its sector by 1.23% and has fallen after two consecutive days of gains. The stock reached an intraday low of Rs 885, representing a drop of 2.21%. Over the past week, Shakti Pumps has seen a return of -2.70%, and over the past month, it has decreased by 6.68%, while its year-to-date performance shows a significant decline of 16.16%. Despite these short-term challenges, the company has demonstrated strong long-term growth, with net sales increasing at an annual rate of 45.73% and operating profit rising by 160.52%. However, the stock is currently trading below all its moving averages, indicating a bearish trend.
In the broader market context, Shakti Pumps has underperformed the benchmark Sensex, which has declined by only 1.22% over the past week and 3.00% over the past month. The stock's recent struggles may be attributed to falling investor participation, as evidenced by a 31.84% drop in delivery volume compared to the five-day average. While the company has shown high management efficiency and consistent returns over the last three years, its current valuation appears expensive with a high Price to Book Value ratio of 9.5. This combination of factors, including a decline in short-term performance and the stock's relative weakness compared to the benchmark, contributes to the current downward movement in Shakti Pumps' stock price.
