Why is Torrent Pharma falling/rising?

As of 31-Jul, Torrent Pharmaceuticals Ltd. is experiencing a price increase, currently at Rs 3,761.20, reflecting a rise of 26.2 points or 0.7%. The stock is trading close to its 52-week high, just 0.77% away, and has outperformed its sector by 2.19% today. Over the past week, Torrent Pharma has shown a strong performance with a return of +7.25%, while its 1-month return stands at +10.19%. The company has demonstrated consistent positive results over the last eight quarters, with a high return on capital employed (ROCE) of 22.33% and a low debt to EBITDA ratio of 1.26 times, indicating strong financial health. However, there is a concern regarding falling investor participation, as the delivery volume has decreased by 26.01% compared to the 5-day average.
In the broader market context, Torrent Pharmaceuticals has significantly outperformed the Sensex, which has declined by 1.22% over the past week, while the stock has risen. Year-to-date, Torrent Pharma has achieved a return of +12.09%, compared to the Sensex's +3.90%. Despite its strong recent performance, there are risks associated with the stock, including a relatively low long-term growth rate in net sales of 8.22% annually over the last five years and a high valuation with a PEG ratio of 3. Nonetheless, the high institutional holdings at 24.75% suggest confidence from larger investors, which may contribute positively to the stock's upward movement.
