Why is Prima Industries falling/rising?

As of 01-October, Prima Industries Ltd is experiencing a decline in its stock price, currently at Rs 35.72, which reflects a decrease of Rs 1.88 or 5.0%. The stock has recently undergone a trend reversal, falling after 17 consecutive days of gains. Although it opened with a 5% gain today, it reached an intraday high of Rs 39.48 before dropping to its current low. The stock has shown high volatility today, trading within a wide range of Rs 3.76, and has underperformed its sector by 9.2%. Despite this decline, Prima Industries has demonstrated strong performance over various periods, with a 1-month return of 87.11% and a 5-year return of 218.08%, indicating a robust overall trend prior to this drop. However, there has been a significant decrease in investor participation, with delivery volume plummeting by 92.67% against the 5-day average, which may have contributed to the recent price decline.
In the broader market context, while Prima Industries has outperformed the Sensex over the past week, month, and year, the benchmark index has shown a slight decline of 0.90% over the past week, contrasting with the stock's impressive 15.41% gain in the same period. This suggests that the stock's recent drop may be more reflective of a profit-taking scenario after a strong rally rather than a broader market downturn. The solvent extraction sector, in which Prima operates, has gained by 4.21%, indicating some positive momentum in the industry. However, the falling investor participation and the stock's volatility today may have led to a cautious sentiment among investors, contributing to the current price decline.
