Trend Analysis
The three major indexes opened 0.43% to 0.85% lower, briefly rebounded after the open with the Shenzhen Component turning positive momentarily, but then fell back again as buying support proved insufficient. By 9:47 AM, the declines in the ChiNext and STAR 50 had widened further from their early morning lows. The Philadelphia Semiconductor Index's eighth consecutive decline, the Nasdaq's single-day drop of over 2%, and the 10-year U.S. Treasury yield holding near a high of 5.19% have pressured growth sector valuations. The fact that the ChiNext and STAR 50 fell more than the Shanghai Composite reflects this transmission effect. Domestic third-quarter economic data and the Financial Street Forum are both landing on the same day, placing policy expectations in an observation window. Since the evening of October 16, multiple STAR Market companies have disclosed chairman buyback proposals, with Changxin Technology planning a buyback of 1 billion to 2 billion yuan, the highest single-company cap in this round for the STAR Market. Capital has flowed out of semiconductors and electronic hardware sectors toward themes such as commercial vehicles, livestock farming, white goods, and FAW-related stocks, showing clear rotation. In the short term, the Shanghai Composite may continue to see fluctuations around the 3,700-point level, and the sustainability of any rebound will depend on whether trading volume can expand in tandem.
