Why is Andhra Petrochem falling/rising?

As of 15-Sep, Andhra Petrochemicals Ltd is experiencing a price increase, currently at Rs 62.92, reflecting a change of 6.08 or 10.7% upwards. The stock has shown strong performance recently, gaining 28.02% over the last four days and outperforming its sector by 9.97% today. It opened with a significant gain of 8.73% and reached an intraday high of Rs 63.25. Despite this positive short-term movement, the company has reported negative results for the last four consecutive quarters, with a substantial decline in operating profit and net sales. Additionally, the company has a low debt-to-equity ratio, but its long-term growth prospects appear poor, as indicated by a negative EBITDA and a significant drop in profits over the past year.
In the broader market context, Andhra Petrochemicals has outperformed the Sensex in the short term, with a 1-week return of 25.09% compared to the Sensex's 1.24%. However, the stock has consistently underperformed against the benchmark over the last three years, with a year-to-date return of -15.41% versus the Sensex's 4.67%. This juxtaposition highlights the stock's volatility and the potential risks associated with its recent gains, particularly given the lack of confidence from domestic mutual funds, which hold only a minimal stake in the company.
