Why is Alembic falling/rising?

As of 13-Oct, Alembic Ltd's stock price is currently at Rs 98.16, reflecting a decrease of Rs 2.22 or 2.21%. The stock has underperformed its sector today by 2.06%, having touched an intraday low of Rs 97.31, which represents a decline of 3.06%. Over the past week, Alembic has seen a return of -3.89%, and its performance over the last year shows a significant decline of -29.23%. The company has reported flat results recently, with net sales at their lowest and a very expensive valuation indicated by a Price to Book Value of 1.1. Despite a healthy long-term growth rate in operating profit, the stock's recent performance has been hindered by a lack of investor confidence, as evidenced by a 14.6% drop in delivery volume compared to the five-day average.
In the broader market context, Alembic's short-term performance has lagged behind the Sensex, which has gained 0.66% over the past week. The stock's underperformance is further highlighted by its negative returns over the past month and year, contrasting sharply with the Sensex's positive returns. Additionally, the absence of domestic mutual fund investment, which stands at 0%, suggests a lack of confidence in the stock's current valuation and business prospects. This combination of poor recent performance, high valuation concerns, and low investor participation contributes to the stock's downward trajectory.
