Why is Sanofi India falling/rising?

As of 22-Sep, Sanofi India Ltd's stock price is currently at 5,020.00, reflecting a decrease of 15.85 points or 0.31%. The stock has been experiencing a downward trend, having fallen for the last three consecutive days, resulting in a total decline of 0.81% during this period. Over the past week, the stock has underperformed with a return of -0.41%, while the Sensex has gained 0.46%. Additionally, the stock has shown a significant decline of 30.22% over the past year, with profits decreasing by 9.4%. Despite having high management efficiency and a low debt-to-equity ratio, the stock is trading at a premium compared to its peers, which may be contributing to its poor performance.
In the broader market context, Sanofi India's short-term performance has lagged behind the benchmark, as indicated by its negative returns compared to the Sensex's positive returns. The stock's long-term growth prospects appear weak, with net sales and operating profit declining over the last five years. Furthermore, the company has reported below-par performance in both the near and long term, which has led to its underperformance relative to the BSE500 index. Although there is rising investor participation, the overall sentiment remains cautious due to the company's flat results and declining profitability.
