Why is Bayer CropSci. falling/rising?

As of 07-Jul, Bayer CropScience Ltd's stock price is currently at 6,390.00, reflecting a decrease of 29.7 points or 0.46%. The stock has recently outperformed its sector by 0.54%, although it has experienced a trend reversal after two consecutive days of gains. Despite this decline, Bayer CropScience has shown positive performance over the past week and month, with returns of 1.91% and 16.30%, respectively. However, the stock has faced challenges, including a significant drop in delivery volume, which fell by 58.13% against the five-day average. While the company boasts a high return on equity (ROE) of 23.22% and a low debt-to-equity ratio, it has also reported poor long-term growth, with operating profit declining at an annual rate of 1.79% over the last five years and a substantial drop in profits of 23.3% over the past year.
In the broader market context, Bayer CropScience's recent performance contrasts with the Sensex, which has seen a slight decline of 0.20% over the past week. The stock's year-to-date return of 15.05% also outpaces the Sensex's 6.79%, indicating a stronger performance relative to the market. However, the stock's long-term performance has been lackluster, with a one-year return of -2.62% compared to the Sensex's gain of 4.31%. This divergence suggests that while Bayer CropScience has had some short-term successes, its overall financial health and growth prospects may be causing investor concern, contributing to the recent decline in stock price.
