SINGAPORE (Reuters) -- NIO stock plunged more than 13% on Thursday, on course for its biggest one-day drop in about six months, as investors fretted over the Chinese electric vehicle maker's outlook amid a U.S. securities lawsuit by Singapore sovereign wealth fund GIC.
The stock fell as far as HK$47 ($6.05), its lowest since Sept. 11, and was the biggest percentage loser on Hong Kong's Hang Seng Tech Index and Hang Seng Automobile Index, which fell 1.5% and 1.7% respectively.
The drop followed a Wednesday report on the lawsuit from Chinese financial news magazine Caixin.
In the lawsuit, filed in August in the U.S district court for the southern district of New York, GIC said NIO and two executives misled investors with false statements and withheld information about its business and prospects.
NIO and GIC declined to comment on Thursday.
GIC is one of the world's largest sovereign wealth funds, managing foreign reserves and investing globally across sectors such as technology and infrastructure.
