Why is Dr Reddy's Labs falling/rising?

As of 05-Aug, Dr Reddy's Laboratories Ltd is experiencing a decline in its stock price, currently at 1,214.90, which reflects a decrease of 10.5 points or 0.86%. The stock is trading below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating a bearish trend. Additionally, there has been a significant drop in investor participation, with delivery volume falling by 53.94% compared to the 5-day average. Over the past week, the stock has underperformed with a return of -6.69%, while the Sensex has only decreased by 0.77%. Year-to-date, Dr Reddy's has seen a decline of 12.49%, contrasting sharply with the Sensex's gain of 3.29%. Despite the company's strong long-term fundamentals, including low debt and a healthy return on equity, these factors have not translated into positive short-term performance.
In the broader market context, Dr Reddy's Laboratories has underperformed significantly compared to the benchmark indices, with a one-year return of -10.88% against the BSE500's positive return of 0.50%. This underperformance is compounded by flat results reported in June and a low return on capital employed, which may have contributed to investor skepticism. While the company boasts strong long-term growth metrics and high institutional holdings, the recent price movement reflects a lack of confidence in its short-term prospects, particularly in light of its recent earnings performance and declining investor engagement.
