Why is Elantas Beck falling/rising?

As of 28-Jul, Elantas Beck India Ltd is experiencing a decline in its stock price, currently at Rs 12,188.00, which represents a decrease of Rs 508.4 or 4.0%. The stock has been underperforming, having fallen consecutively for the last five days, resulting in a total decline of 12.04% over the past week. Today's trading saw the stock reach an intraday low of Rs 12,051.1, indicating a significant drop of 5.08%. Additionally, the stock's performance has been weaker than its sector, with a 3.31% underperformance noted today. Despite a high management efficiency reflected in a return on equity of 15.14% and a low debt-to-equity ratio, the stock's recent movement suggests a lack of investor confidence, as evidenced by a decrease in delivery volume.
In the broader market context, Elantas Beck's short-term performance has been notably worse than the benchmark Sensex, which has only declined by 1.59% over the same week. While the stock has shown positive returns over the longer term, including a 2.20% increase over the past year and a remarkable 190.25% rise over the last three years, the recent trend indicates a shift in sentiment. The stock's year-to-date performance is down by 4.78%, contrasting with the Sensex's gain of 3.52%, highlighting a divergence in performance that may be contributing to the current downward pressure on the stock price.
