Nanshan Aluminium International's stock plummeted 5.97% during intraday trading on Friday. The sharp decline comes as the market reacts to an impending share unlock event.

The sell-off is attributed to the upcoming unlock of approximately 31 million shares held by the company's controlling shareholder, scheduled for April 28. This volume represents roughly 5% of the total share capital. Despite the unlock being relatively limited compared to the total outstanding shares and free float, its proximity has prompted some investors to rebalance their positions preemptively, amplifying short-term selling pressure.

Fundamentally, the company recently reported strong financials, including a 124.19% year-over-year net profit growth and substantially improved gross margins, reflecting robust underlying business performance in aluminum smelting, processing, and sales. However, these positive fundamentals appear to be overshadowed in the near term by the technical overhang of the impending share unlock.
