Why is John Cockerill falling/rising?

As of 19-Sep, John Cockerill India Ltd's stock price is rising, currently at 5,321.55, reflecting an increase of 264.0 or 5.22%. The stock has shown strong performance recently, gaining 21.36% over the last four days and outperforming its sector by 5.28% today. It has consistently outperformed the benchmark Sensex, with a 20.06% increase over the past week compared to the benchmark's 0.88%. However, despite these positive short-term movements, the company faces significant challenges, including a weak long-term fundamental strength indicated by a -268.42% CAGR growth in operating profits over the last five years and a negative EBITDA, which raises concerns about its profitability and ability to service debt.
Broader market context shows that while John Cockerill has outperformed the Sensex in the short term, the overall market has been relatively stable. The stock's impressive returns over the past three years, coupled with a consistent performance against the BSE500, suggest a strong investor interest. However, the lack of domestic mutual fund investment, which stands at 0%, may indicate caution among institutional investors regarding the company's long-term viability. This juxtaposition of strong recent performance against underlying financial weaknesses creates a complex picture for potential investors.
