Why is Emerald Tyre falling/rising?

As of 12-Sep, Emerald Tyre Manufacturers Ltd is experiencing a price increase, currently at 129.45, with a change of 0.8, representing a rise of 0.62%. The stock has outperformed its sector today by 1.01%, indicating a positive movement relative to its peers. However, over the past week, the stock has declined by 4.99%, and it has also seen a significant drop of 27.90% year-to-date. Despite these declines, there has been a notable increase in investor participation, with delivery volume rising by 67.91% compared to the 5-day average, suggesting growing interest in the stock. Unfortunately, there is no information available regarding positive or negative factors that could further clarify the stock's recent movement.
In the broader market context, the stock's performance over the past week is notably worse than the benchmark Sensex, which has gained 1.51% during the same period. This stark contrast highlights the challenges Emerald Tyre is facing in the current market environment, as it has underperformed significantly compared to the benchmark over the past month and year-to-date. The liquidity of the stock remains adequate, being based on 2% of the 5-day average traded value, which supports trading activity despite the overall negative trends in its returns.
