Why is Sanofi India falling/rising?

As of 16-Sep, Sanofi India Ltd is experiencing a decline in its stock price, currently at 5,029.45, which reflects a decrease of 11.05 points or 0.22%. The stock has underperformed its sector by 0.74% today and has been on a downward trend for the last three days, accumulating a total loss of 1.15% during this period. Over the past week, the stock has also shown a slight decline of 0.21%, while its performance over the last month is down by 1.19%. Notably, despite a high management efficiency indicated by a return on equity (ROE) of 35.83% and a low debt-to-equity ratio, the stock has generated a significant return of -30.10% over the past year, alongside a 9.4% drop in profits. This combination of factors suggests that while the company has some positive attributes, the overall financial performance and recent results have led to negative sentiment among investors.
In the broader market context, Sanofi India's recent performance contrasts sharply with the Sensex, which has increased by 1.58% over the past week and 2.21% over the last month. The stock's long-term growth prospects appear poor, with net sales declining at an annual rate of 8.57% and operating profit down by 5.45% over the last five years. Additionally, the company's recent quarterly results showed a significant drop in profit before tax and profit after tax compared to previous averages, further contributing to its underperformance against the benchmark indices. The high institutional holdings at 28.67% indicate that more informed investors are also cautious, reflecting a lack of confidence in the stock's future performance amidst its declining returns.
