Shares in online fast-fashion retailer Shein dropped 4% in their first day of trading in Hong Kong on Tuesday after slumping as much as 10%, with investors worried about the impact of setbacks of its long-delayed ⁠listing potentially undermining its competitive advantages.

Known globally for selling $5 tops ⁠and $10 dresses, Shein has been humbled by tariff and duty changes in the U.S. and Europe that have contributed to a dramatic decline in valuation for the company.

Founded in China in 2012 and headquartered in Singapore since late 2021, Shein spent years touting its credentials as a global ​company before re-embracing its roots to list in Hong Kong.

That capped a four-year quest to go public ​after ⁠failing to list in New York and London. Intense scrutiny of its business practices also hampered its attempts, which were ultimately blocked by Chinese authorities.

Its shares traded at HK$46.62 ($5.95) by mid-session, down from its HK$48.56 ($6.19) IPO price tag, but recovering somewhat from an earlier slide of as much as 10%.
