Why is Sanofi India falling/rising?

As of 15-Sep, Sanofi India Ltd's stock price is currently at 5,040.50, reflecting a decline of 29.0 points or 0.57%. The stock has been experiencing a downward trend, having fallen for the last two days with a total return of -0.7% during this period. Additionally, it is trading below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating a bearish momentum. The stock has underperformed significantly over various time frames, with a year-to-date decline of 17.36% and a one-year drop of 29.52%. Despite having high management efficiency and a low debt-to-equity ratio, the stock's poor long-term growth, with net sales decreasing at an annual rate of -8.57%, and a recent flat performance in quarterly results, have contributed to its negative price movement.
In the broader market context, Sanofi India's recent performance contrasts sharply with the benchmark Sensex, which has gained 1.24% over the past week and 1.47% over the past month. This underperformance is further highlighted by the stock's significant decline compared to the Sensex's 4.67% increase year-to-date. The falling investor participation, as evidenced by a 28.98% drop in delivery volume, also suggests a lack of confidence among traders. While the stock has high institutional holdings, which typically indicate a level of confidence in the company's fundamentals, the overall negative sentiment surrounding its recent financial results and long-term growth prospects has led to its current decline.
