Why is Sanofi India falling/rising?

As of 24-Sep, Sanofi India Ltd's stock price is currently at 4,994.30, reflecting a decrease of 10.6 points or 0.21%. The stock has been on a downward trend, losing value for the last five consecutive days, with a total decline of 1.31% over the past week. It has underperformed significantly over longer periods, with a year-to-date drop of 18.12% and a staggering 30.37% decrease over the past year. Despite a high return on equity (ROE) of 35.83% and low debt levels, the company's financial performance has been disappointing, with net sales and operating profit declining over the last five years. Recent quarterly results also showed substantial falls in net sales and profit before tax compared to previous averages, contributing to the stock's negative sentiment.
In the broader market context, Sanofi India's recent performance has been worse than the benchmark Sensex, which has seen a slight increase of 0.50% over the past month. The stock's performance is particularly concerning given its long-term underperformance relative to the BSE500 index, indicating a lack of investor confidence. While there has been a rise in investor participation, as evidenced by an increase in delivery volume, the overall liquidity and trading conditions suggest that the stock is not attracting sufficient positive momentum to counteract its recent declines.
