Golden Finance reported that JPMorgan Chase's latest September research report on A-shares showed that the Political Bureau meeting unexpectedly called for strong policies to stimulate the strong rebound of A-shares. This round of rebound was driven by three major factors: a decline in the short selling ratio, an increase in margin trading, and investor excitement. Specifically, as of September 30, the short selling ratio in the Hong Kong market fell from 21.8% on September 16 to 10.2%; the proportion of margin trading in A-shares in total trading volume rose from 7.4% on September 20 to 10.5% on September 27. JPMorgan Chase believes that the excitement of retail investors and the surge in the number of new accounts are evidence that global funds may narrow their exposure to the Chinese stock market. JPMorgan Chase also predicted that from September 23 to 27, the net inflow of A-share ETF funds was 59.3 billion yuan (about 8.5 billion US dollars). JPMorgan Chase pointed out that the sustainability of the A-share rebound lies in the strength of fiscal policy, macro data and earnings revisions.
