Why is Sun Pharma.Inds. falling/rising?

As of 01-Sep, Sun Pharmaceutical Industries Ltd is experiencing a decline in its stock price, currently at Rs 1,564.20, which reflects a decrease of Rs 29.85 or 1.87%. The stock has underperformed today, with a performance that is 1.84% lower than its sector. It has also touched an intraday low of Rs 1,556.25, indicating a downward trend. Over the past week, the stock has decreased by 5.58%, and year-to-date, it has fallen by 17.00%. Despite these declines, the company maintains a strong long-term fundamental strength, characterized by low debt and healthy growth in net sales and operating profit. High institutional holdings at 36.75% suggest confidence among knowledgeable investors, although the stock's current trading is below all key moving averages.
In the broader market context, Sun Pharma's recent performance contrasts with the benchmark Sensex, which has only declined by 1.56% over the past week and has gained 2.85% year-to-date. This indicates that while the overall market is experiencing a slight downturn, Sun Pharma is facing a more significant drop. The stock's liquidity remains adequate, and rising investor participation, as evidenced by increased delivery volume, may provide some support. However, the proximity to its 52-week low and the overall negative short-term returns compared to the benchmark suggest ongoing challenges for the stock in the current market environment.
