Why is Sanofi India falling/rising?

As of 13-Aug, Sanofi India Ltd's stock price is currently at 5,063.20, reflecting a decrease of 30.25 points or 0.59%. The stock has been underperforming, as evidenced by its performance today, where it has fallen for three consecutive days, resulting in a total decline of 2.99%. Additionally, it is trading below all key moving averages, indicating a bearish trend. Over the past week, the stock has dropped by 5.11%, and its year-to-date performance shows a significant decline of 16.99%. Despite high management efficiency and positive financial results in March, the stock's long-term growth prospects appear poor, with net sales and operating profit declining over the last five years. This has contributed to a negative sentiment surrounding the stock, reflected in its substantial underperformance compared to the broader market.
In the broader market context, Sanofi India's recent performance contrasts sharply with the Sensex, which has shown a slight decline of only 0.01% over the past week. While the Sensex has gained 3.07% year-to-date, Sanofi India has faced a steep decline, highlighting its struggles relative to the market. The stock's negative returns over various periods, including a 24.04% drop in the last year, further emphasize its underperformance against the benchmark indices. The falling investor participation, with a significant drop in delivery volume, suggests a lack of confidence among investors, which is compounded by the stock's inability to generate positive returns in both the short and long term.
