Why is RDB Rasayans falling/rising?

As of 01-September, RDB Rasayans Ltd is experiencing a price increase, currently at Rs 162.80, reflecting a rise of 3.8 or 2.39%. Today's price summary indicates that the stock opened with a gain of 3.08% and reached an intraday high of Rs 163.9. Despite this positive movement, the stock has underperformed its sector by 0.26% and has seen a decline in delivery volume, which fell by 59.37% against the 5-day average. Over the past week, the stock has decreased by 1.33%, and its performance over the last month shows a decline of 5.29%. However, it has shown resilience with a year-to-date return of 2.71% and a significant increase of 54.97% over the past three years. The company's low debt-to-equity ratio and a fair valuation with a PEG ratio of 0.9 suggest a stable financial position, which may contribute to the stock's recent upward movement.
In the broader market context, the Sensex has also faced challenges, with a decline of 1.56% over the past week and a slight decrease of 0.29% over the past month. While RDB Rasayans has outperformed the benchmark on a year-to-date basis, its one-year return of -4.24% is worse than the Sensex's decline of 2.43%. This indicates that while the stock is currently rising, it has struggled in the short term compared to the broader market. The recent gain may be a reaction to the overall sector performance, as the packaging sector has gained by 2.64%, suggesting some positive sentiment in related industries.
