In the broader market context, the Sensex has increased by 1.80% over the past week, while Eighty Jewellers has outperformed this benchmark with a 7.87% gain. However, the stock has underperformed the Sensex over the longer periods, with a year-to-date decline of 29.93% compared to the Sensex's gain of 6.24%.
