Why is Divi's Lab. falling/rising?

As of 17-Sep, Divis Laboratories Ltd's stock price is currently at 6,056.10, reflecting a decrease of 24.75 points or 0.41%. The stock has underperformed its sector today by 0.45% and has experienced a trend reversal, falling after two consecutive days of gains. Its performance over the past week shows a slight increase of 0.40%, but over the past month, it has declined by 1.21%. The stock is currently trading higher than its 5-day moving averages but lower than its 20-day, 50-day, 100-day, and 200-day moving averages. Additionally, there has been a significant drop in investor participation, with delivery volume falling by 46.26% compared to the 5-day average. Despite these challenges, the company has demonstrated high management efficiency, a low debt-to-equity ratio, and positive financial results over the last four quarters, which may support its valuation.
In the broader market context, the stock's recent performance contrasts with the benchmark Sensex, which has risen by 1.56% over the past week and 2.60% over the past month. While Divis Laboratories has outperformed the market over the past year with an 11.27% return compared to the Sensex's -0.46%, its year-to-date performance shows a decline of 0.72% against the benchmark's gain of 5.83%. This underperformance in the short term, coupled with falling investor interest, may contribute to the stock's current decline, despite its strong fundamentals and institutional support.
