Why is South. Magnesium falling/rising?

As of 27-Jun, Southern Magnesium & Chemicals Ltd's stock price is currently at 131.25, reflecting an increase of 2.55 or 1.98%. The stock has shown a strong performance recently, gaining 10.29% over the past week and outperforming its sector by 1.23% today. However, despite this short-term gain, the stock has experienced significant declines over longer periods, with a year-to-date drop of 49.71% and a one-year return of -40.60%. The company is facing challenges, including operating losses and a weak long-term fundamental strength, as indicated by a negative PAT growth of -50.18% and a low PBDIT. Additionally, the stock is trading at a premium compared to its peers, which may deter potential investors.
In the broader market context, the stock's recent short-term performance contrasts sharply with the benchmark, as the Sensex has only increased by 2.00% over the past week. This underperformance is further highlighted by the stock's negative returns over the past year, where it has lagged behind the BSE 500's positive return of 4.10%. The falling investor participation, evidenced by a significant drop in delivery volume, suggests a lack of confidence among investors, which could contribute to the stock's volatility despite its recent gains.
