Why is Alembic falling/rising?

As of 23-Jul, Alembic Ltd's stock price is currently at 119.00, reflecting an increase of 0.8, or 0.68%. The stock has shown mixed performance recently, with a decline of 1.90% over the past week, but a notable increase of 7.79% over the last month. Today's price summary indicates that the stock is performing in line with its sector, although it has seen a significant drop in investor participation, with delivery volume falling by 41.48% compared to the 5-day average. Despite a healthy long-term growth rate in operating profit and positive results over the last six quarters, the stock's valuation appears expensive, and it has underperformed the market over the past year, generating a return of -15.57%.
In the broader market context, Alembic Ltd's recent performance contrasts with the Sensex, which has gained 0.11% over the past week and 1.01% over the past month. While the stock has shown some recovery in the short term, it still lags behind the benchmark significantly over the longer term, with a year-to-date decline of 10.02% compared to the Sensex's increase of 5.87%. The lack of domestic mutual fund investment may indicate a lack of confidence in the stock's current valuation, further contributing to its underperformance relative to the broader market.
