In the broader market context, the stock's short-term performance has been notably weaker than the benchmark, as evidenced by its 1-week and 1-month returns compared to the Sensex. While the Sensex has increased by 1.43% over the past week and 2.84% over the past month, Emerald Tyre's declines highlight a significant underperformance.
