Why is Rel. Chemotex falling/rising?

As of 22-Sep, Reliance Chemotex Industries Ltd is currently priced at Rs 161.00, reflecting an increase of Rs 1.0 or 0.62%. The stock has shown a significant performance today, having gained after three consecutive days of decline, and opened with a notable gap up of 19.97%. It reached an intraday high of Rs 191.95, although it also experienced a low of Rs 156.2, indicating high volatility with an intraday fluctuation of 19.22%. Despite this positive movement today, the stock has underperformed over the longer term, with a year-to-date decline of 23.33% compared to a 5.15% increase in the Sensex, and a one-year drop of 28.65% against a slight decline in the benchmark.
Broader Market Context: In the short term, Reliance Chemotex's performance has been weaker than the benchmark, as it has fallen by 0.86% over the past week while the Sensex has gained 0.46%. This underperformance is further highlighted by the stock's negative returns over the past month and year, contrasting sharply with the benchmark's positive performance. However, the recent increase in delivery volume, which rose by 115.35% against the five-day average, suggests a rising interest among investors, potentially indicating a reversal in sentiment despite the stock's overall downward trend in the longer term.
