The gut-churning moves come after outsized gains by small-cap IPOs in the city this month lured investors. EuroEyes International Eye Clinic shares rose as much as 102% on their Oct 15 debut, while shares of software developer 360 Ludashi Holdings more than tripled on Oct 10. The 14 IPOs this month through Tuesday climbed an average 43% on their first day, according to Bloomberg data.
Speculators are piling into IPOs given the lack of direction in the broader market, according to Castor Pang, head of research at Core Pacific-Yamaichi International. The Hang Seng Index has fallen 12% from its April high amid concern about the US-China trade war and months of protests in Hong Kong.
