Why is Cohance Life falling/rising?

As of 24-Sep, Cohance Lifesciences Ltd is experiencing a decline in its stock price, currently at Rs 897.10, reflecting a decrease of Rs 1.7 or 0.19%. The stock has been on a downward trend, losing value for the past six consecutive days, resulting in a total decline of 9.35% during this period. Additionally, it is trading 4.48% above its 52-week low and is below all key moving averages, indicating weak performance. The company has shown poor long-term growth, with operating profit growing at only 2.95% annually over the last five years, and a significant drop in PAT by 41.1% in the most recent quarter. Furthermore, 100% of promoter shares are pledged, which can exert additional downward pressure in a falling market.
In the broader market context, Cohance Lifesciences has underperformed compared to the Sensex, with a one-week return of -7.23% against the benchmark's -1.18%. While the stock has shown a slight positive return of 1.13% over the past month, its year-to-date performance is significantly worse, with a decline of 20.85% compared to the Sensex's gain of 4.58%. This stark contrast highlights the stock's struggles relative to the market, compounded by falling investor participation, as evidenced by a 90.87% drop in delivery volume. Overall, the combination of poor financial results, high valuation, and pledged shares contributes to the stock's recent downward movement.
