Why is Chemtech Indust. falling/rising?

As of 07-Jul, Chemtech Industrial Valves Ltd is currently priced at 121.95, reflecting an increase of 1.2 (0.99%). The stock has been gaining for the last three days, with a total return of 2.44% during this period, outperforming its sector by 0.54%. However, despite this recent uptick, the stock has underperformed over the past week, down 1.61%, and has significantly lagged behind the benchmark indices over the past month and year, with returns of -9.80% and -37.46%, respectively. Positive factors include a notable growth in profit after tax and net sales, but the stock faces challenges due to weak long-term fundamentals, indicated by a low return on equity and a high debt-to-EBITDA ratio, which may contribute to its valuation concerns.
Broader market context shows that while Chemtech's recent performance has been positive, it remains in a challenging position compared to the broader market. The Sensex has shown a slight decline of 0.20% over the past week, but Chemtech's performance is still significantly worse over longer periods, particularly with a year-to-date decline of 43.36% against the Sensex's gain of 6.79%. This stark contrast highlights the stock's ongoing struggles despite recent gains, suggesting that investor sentiment may still be cautious due to its long-term performance and fundamental weaknesses.
