However, the stock's year-to-date and one-year returns are significantly lagging behind the benchmark, which has gained 8.36% and 9.48% respectively. This disparity suggests that while the stock has had some short-term gains, its overall performance is not keeping pace with the broader market, contributing to the recent decline in price.
