On September 4, the stock ETF market witnessed a net outflow of 9.5 billion yuan. Notably, ETFs specializing in sectors and themes like securities, Hong Kong stock technology robots, and dividends recorded the largest net inflows of funds. Conversely, broad-based ETFs tracking indices such as the STAR Market, ChiNext, and CSI 300, along with industry-themed ETFs in areas like chip semiconductors and artificial intelligence, experienced substantial outflows. Despite significant net inflows over the previous two trading days, stock ETFs as a whole maintained a net inflow trend for the week. However, the cumulative net inflow since the start of September has been less than 5 billion yuan.
