Why is Chemtech Indust. falling/rising?

As of 29-Sep, Chemtech Industrial Valves Ltd is experiencing a decline in its stock price, currently at Rs 117.00, reflecting a decrease of Rs 5.8 or 4.72%. The stock has underperformed its sector by 5.35% today and has been on a downward trend for the last two days, accumulating a total loss of 8.77% in that period. Despite opening with a gain of 2.61% and reaching an intraday high of Rs 126, it fell to a low of Rs 115.5. Over the past week, the stock has seen a significant decline of 12.03%, and its year-to-date performance shows a staggering drop of 45.66%. Although there were positive results reported in June, including the highest PBDIT and operating profit margins, the stock's overall performance has been overshadowed by its substantial losses over the past year and its high valuation metrics, such as a Price to Book Value of 2.2.
In the broader market context, the stock's recent performance contrasts sharply with the benchmark Sensex, which has only declined by 2.18% over the past week. The stock's long-term returns are also concerning, with a 55.92% drop over the past year, indicating a significant underperformance compared to the BSE500 index. The falling investor participation, evidenced by a 69.73% decrease in delivery volume, further exacerbates the stock's challenges. Despite a high return on equity of 8.2% and a PEG ratio of 0.9 indicating potential value, the stock's expensive valuation and poor performance relative to its peers suggest that investors remain cautious, contributing to the ongoing decline in its price.
