Why is Bayer CropSci. falling/rising?

As of 05-Sep, Bayer CropScience Ltd is experiencing a decline in its stock price, currently at 5,100.00, reflecting a decrease of 19.9 points or 0.39%. The stock has been underperforming, with a consecutive fall over the last three days resulting in a total decline of 2.5%. It is trading below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating a bearish trend. Despite a recent increase in investor participation, as evidenced by a 21.9% rise in delivery volume, the stock has shown significant underperformance over various time frames, including a 20.75% drop over the past year. While the company boasts high management efficiency with a return on equity (ROE) of 22.83% and low debt levels, it faces challenges with poor long-term growth, as operating profit has decreased at an annual rate of 3.98% over the last five years.
In the broader market context, Bayer CropScience's performance contrasts sharply with the benchmark, as it has generated a return of -2.14% over the past week while the Sensex has gained 1.13%. This consistent underperformance against the benchmark is evident over the last three years, where the stock has lagged behind the BSE500 in each annual period. Although the company reported positive growth in net sales and profit after tax in the latest six months, the overall sentiment remains negative due to falling profits and an expensive valuation relative to its peers. This combination of factors contributes to the stock's current downward trajectory.
