Why is Sanofi Consumer falling/rising?

As of 13-Nov, Sanofi Consumer Healthcare India Ltd's stock price is rising, currently at 4,986.40, reflecting an increase of 329.1 or 7.07%. The stock has outperformed its sector by 7.13% today and has experienced consecutive gains over the last two days, with an overall return of 8.63% during this period. It reached an intraday high of Rs 5072.45, indicating strong upward momentum. Despite this positive movement, there is a notable decline in investor participation, with delivery volume falling by 80.89% against the five-day average. The company boasts high management efficiency with a return on equity (ROE) of 73.93% and a low debt-to-equity ratio, which supports its healthy long-term growth, evidenced by significant increases in net sales and operating profit. However, the stock's valuation is considered very expensive, with a price-to-book value of 44.7, and its profits have decreased by 27% over the past year, which could temper investor enthusiasm.
In the broader market context, Sanofi's stock has shown a strong short-term performance, with a 5.35% increase over the past week, significantly outpacing the Sensex's 1.40% rise. Over the past month, the stock has gained 7.91%, again outperforming the benchmark's 2.61% increase. However, year-to-date, the stock's performance of 1.04% lags behind the Sensex's 8.11% return, indicating that while the stock is currently rising, it has not kept pace with the broader market over a longer timeframe. This divergence may reflect investor caution due to the company's recent profit decline despite its operational strengths.
