Why is Sandur Manganese falling/rising?

As of 01-Sep, Sandur Manganese & Iron Ores Ltd is currently priced at 433.55, reflecting a slight increase of 0.65 or 0.15%. However, the stock has underperformed its sector today by 1.17%, and it is trading below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages. Over the past week and month, the stock has declined by 2.75%, while it has shown a year-to-date increase of 4.34%. Despite positive financial indicators such as a low Debt to EBITDA ratio of 0.44 times, strong net sales growth, and consistent positive quarterly results, the stock's recent performance is hindered by falling investor participation, particularly from institutional investors, who have reduced their stake by 0.95% in the last quarter.
In the broader market context, Sandur Manganese's short-term performance has been weaker than the benchmark, with a 1-week decline of 2.75% compared to the Sensex's decline of 1.56%. This underperformance is indicative of broader market trends, where the stock has not only lagged behind the benchmark in the short term but also in the longer term, with a 1-year return of -14.51% against the Sensex's -2.43%. The combination of declining institutional interest and the stock's inability to maintain momentum despite strong financial fundamentals suggests a cautious outlook for investors.
