Why is Cohance Life falling/rising?

As of 28-Aug, Cohance Lifesciences Ltd is experiencing a decline in its stock price, currently at Rs. 878.85, reflecting a decrease of 7.05 points or 0.8%. The stock has hit a new 52-week low of Rs. 856.9 today and has been on a downward trend, losing 2.15% over the last two days. Over the past month, the stock has fallen by 12.11%, significantly underperforming the benchmark Sensex, which has only decreased by 1.00%. Additionally, the company's operating profit growth has been poor, with a mere annual increase of 2.95% over the last five years, and a substantial drop in PAT of 41.1% compared to the previous quarter's average. The high percentage of pledged promoter shares, which has increased by 100% in the last quarter, adds further downward pressure on the stock.
In the broader market context, while the Sensex has shown a decline of 2.34% over the past week, Cohance Lifesciences Ltd has outperformed this benchmark slightly with a loss of only 1.50%. However, the stock's year-to-date performance is concerning, with a decline of 22.46% compared to the Sensex's gain of 2.48%. The stock's liquidity is adequate, but the overall sentiment is negative due to its poor long-term growth prospects and high valuation relative to its peers. This combination of factors has contributed to the stock's continued decline in a challenging market environment.
