Why is SPIC falling/rising?

As of 23-Sep, Southern Petrochemical Industries Corporation Ltd. is experiencing a decline in its stock price, currently at Rs 96.60, which reflects a decrease of Rs 1.75 or 1.78%. The stock has been underperforming significantly, having fallen for the last 14 consecutive days, resulting in a total decline of 21.37%. In the past week, the stock has dropped by 7.96%, while over the last month, it has decreased by 12.56%. Despite this downturn, the company has shown strong fundamentals, including a low Debt to EBITDA ratio of 1.18 times and impressive growth in operating profit at an annual rate of 31.47%. However, the stock's recent performance has been negatively impacted by falling investor participation, as evidenced by a 7.17% decrease in delivery volume compared to the five-day average.
Broader market context indicates that while the stock has underperformed in the short term, it has outperformed the benchmark Sensex over longer periods, generating a return of 11.53% over the past year compared to the Sensex's decline of 3.33%. The stock's liquidity remains adequate for trading, but the recent consecutive falls and lower participation may be causing concern among investors. Institutional investors have increased their stake, indicating confidence in the company's long-term potential, yet the current market sentiment appears to be overshadowed by the stock's recent poor performance and declining trading activity.
