There seems to be no obvious reason behind this, or perhaps because investors changed their minds about the Fed's dovish approach the day before.

The Fed announced a 50 basis point rate hike on Wednesday, and Fed Chairman Jerome Powell made it clear that the Federal Open Market Committee was not considering a 75 basis point range of rate hikes. This boosted investor confidence, and US stocks moved higher on Wednesday.

On May 4, the US Securities and Exchange Commission (SEC) updated its list to show that NIO, XPeng and 86 other companies were added to the list of companies that are facing possible delisting.

NIO subsequently said that it will continue to comply with applicable Chinese and US laws and regulations and work to maintain its listing status on the New York Stock Exchange and Hong Kong Stock Exchange.

NIO has been actively exploring possible solutions to protect the interests of its stakeholders, it said.

Earlier Friday, NIO announced that it will list by way of introduction in Singapore and has received a conditional listing eligibility letter from the local exchange.
