Why is Alembic falling/rising?

As of 12-Sep, Alembic Ltd's stock price is currently at 103.25, reflecting a decrease of 1.15, or 1.1%. The stock has been underperforming, with a performance today that is 1.39% lower than its sector. It has experienced consecutive declines over the last two days, with a total drop of 1.67%. Additionally, Alembic's returns over the past week, month, and year are -1.48%, -4.84%, and -33.58%, respectively, indicating a significant underperformance compared to the Sensex, which has shown positive returns during the same periods. While the company has a low debt-to-equity ratio and healthy long-term growth in operating profit, the recent flat results in net sales and profit before tax have raised concerns. The stock's valuation appears expensive relative to its return on equity, and the lack of domestic mutual fund investment suggests a lack of confidence in the stock's price.
Broader Market Context: In the context of the broader market, Alembic's short-term performance is notably weaker than the Sensex, which has gained 1.48% over the past week while Alembic has lost 1.48%. This trend of underperformance continues in the longer term, with Alembic's returns lagging behind the benchmark over the past one and three years. The overall market sentiment appears to favor other stocks, as evidenced by the rising investor participation in Alembic, which may not be sufficient to counteract the negative sentiment stemming from its recent financial results and valuation concerns.
