Why is Bayer CropSci. falling/rising?

As of 30-Jul, Bayer CropScience Ltd's stock price is currently at Rs 6,308.00, reflecting a decrease of Rs 46.85 or 0.74%. The stock has underperformed its sector today by 1.21% and has experienced a trend reversal, falling after two consecutive days of gains. Over the past week, the stock has declined by 0.27%, while it has shown a modest increase of 0.60% over the past month. Year-to-date, the stock has performed well with a gain of 13.58%, contrasting with a 9.11% decline over the past year. Despite having a high return on equity of 23.22% and a low debt-to-equity ratio, which are positive indicators, the recent drop in delivery volume by 11.07% against the 5-day average suggests a decrease in investor participation, contributing to the stock's current downward movement.
In the broader market context, Bayer CropScience's performance has been relatively better than the benchmark Sensex in the year-to-date period, where the Sensex has only increased by 4.28%. However, in the short term, the stock's decline of 0.27% over the past week contrasts with the Sensex's larger drop of 1.50%, indicating that while the stock has been resilient over a longer timeframe, it is currently facing challenges that are affecting its immediate performance. The liquidity of the stock remains adequate for trading, but the overall market sentiment appears to be weighing on its price, as evidenced by the recent underperformance relative to both the sector and the benchmark.
