Why is Citichem India falling/rising?

As of 01-Oct, Citichem India Ltd's stock price is rising, currently at Rs 27.55, reflecting an increase of Rs 1.41 or 5.39%. The stock has shown strong performance today, outperforming its sector by 5.1% and has been on a consecutive gain for the last two days, accumulating a total return of 5.96% during this period. Notably, the stock opened with a significant gain of 18.59% today and reached an intraday high of Rs 31. However, there are signs of erratic trading, as the stock did not trade on one day out of the last 20, and there has been a notable decline in investor participation, with delivery volume dropping by 58.33% compared to the 5-day average. The stock is currently trading higher than its 5-day moving averages but lower than its longer-term moving averages, indicating mixed momentum.
In the broader market context, Citichem's short-term return of 2.04% over the past week contrasts sharply with the Sensex, which has declined by 0.90% during the same period. This indicates that Citichem is performing well relative to the overall market. However, over the past month, the stock has underperformed with a decline of 5.00%, while the Sensex has gained 0.77%. The high volatility observed today, with an intraday volatility of 6.49%, suggests that while the stock is experiencing upward momentum, it is also subject to significant price fluctuations, which could be a concern for investors.
