Why is Chemtech Indust. falling/rising?

As of 14-Nov, Chemtech Industrial Valves Ltd is experiencing a significant decline in its stock price, currently at Rs. 101.05, reflecting a decrease of Rs. 11.85 or 10.5%. The stock has hit a new 52-week low of Rs. 95 today, following a consecutive fall over the last two days, resulting in a total drop of 11.36%. It opened with a substantial loss of 15.85% and has been trading below all key moving averages, indicating a bearish trend. Additionally, the stock has underperformed its sector by 11.37% today and has shown a drastic decline in investor participation, with delivery volume falling by 37.98% compared to the five-day average. Despite positive financial results reported in June, such as a record operating profit margin, the stock's valuation remains high with a Price to Book Value of 1.9, and it has underperformed the market significantly over the past year with a return of -51.97%.
In the broader market context, the stock's performance has been notably poor compared to the benchmark Sensex, which has gained 1.62% over the past week and 3.09% over the past month. While Chemtech has seen a remarkable increase of 436.07% over the last three years, its recent performance starkly contrasts with the overall market trend, where the BSE500 has generated returns of 8.00% in the last year. This underperformance, coupled with a high PEG ratio of 9.2, suggests that the stock is not only expensive relative to its earnings growth but also reflects a lack of confidence among investors, contributing to its declining price.
