In specific company news, a team of analysts from Haitong International released an 87-page research report on June 26 showing details of their disassembly of a BYD model. It was the first time local analysts had done so, generating widespread attention and media coverage.
On June 21, Citi adjusted its approach to valuing China's electric vehicle sector and revised its price targets for major EV companies.
The team previously valued the Chinese EV sector based on P/S (price-to-sales), but they believe a more reasonable approach should be based on PEG (price/earnings-to-growth), thus making revenue per share and expected growth rate more important.
Based on the new valuation methodology, Citi lowered their price target on NIO from $87 to $41.1 and raised their price target on XPeng from $36.7 to $51.59.
They also raised their price target on Li Auto to $58.60 from $26.80 and raised their price target on BYD trading in Hong Kong to HK$640 from HK$587.
Citi maintained its Buy ratings on all four companies.
