Over the past month, the stock has risen by 45.80%, while the benchmark has seen a modest gain of 1.39%. This strong performance relative to the market may reflect positive sentiment towards the company, despite the drop in delivery volume, which could suggest that while the stock is currently in demand, the sustainability of this rise may be questioned if investor participation continues to decline.
