Why is Chemtech Indust. falling/rising?

As of 25-Aug, Chemtech Industrial Valves Ltd is experiencing a price increase, currently at Rs. 106.30, reflecting a change of 0.7 (0.66%) upward. The stock has recently outperformed its sector by 0.65% and has shown a trend reversal by gaining after three consecutive days of decline. However, it has hit a new 52-week low of Rs. 95.95 today. Over the past week, the stock has underperformed with a return of -1.71%, and it has significantly declined by 60.98% over the past year, despite a 58% increase in profits during the same period. The company's fundamentals are weak, indicated by a low return on equity (ROE) of 8.7 and a high debt-to-EBITDA ratio of 3.81, which contribute to its classification as a strong sell.
In the broader market context, the stock's short-term performance has been notably worse than the benchmark, with the Sensex gaining 0.45% over the past week while Chemtech has fallen. The stock's long-term performance is also concerning, as it has underperformed the market significantly over the past year, with the BSE500 index returning -2.11%. Despite the recent positive operational results, the overall sentiment remains negative due to the company's weak long-term fundamentals and high valuation metrics, which overshadow the recent price increase.
