Why is Roto Pumps falling/rising?

As of 01-Aug, Roto Pumps Ltd is experiencing a decline in its stock price, currently at Rs 86.40, reflecting a decrease of Rs 2.4 or 2.7%. The stock has underperformed its sector by 1.54% today and has been on a consecutive downward trend for the last two days, accumulating a total loss of 6.54% during this period. Over the past week, the stock has decreased by 4.21%, and in the last month, it has fallen by 12.54%. Despite a high management efficiency indicated by a return on capital employed (ROCE) of 24.19% and a low debt-to-equity ratio of 0.07, these positive factors have not been sufficient to counteract the recent negative price movements.
In the broader market context, Roto Pumps' recent performance contrasts sharply with the Sensex, which has only declined by 1.06% over the past week. This suggests that the stock's short-term performance is significantly lagging behind the benchmark. Additionally, while the stock's delivery volume has increased by 56.97% against the five-day average, indicating rising investor participation, the overall market sentiment appears to be unfavorable, contributing to the stock's decline.
