A-share market experienced significant volatility over the two trading days following the holiday period. Technology stocks plunged yesterday, and early trading today saw another sharp decline, with the STAR Market index briefly dropping over 4%. However, the market stabilized in the afternoon as major institutional buyers stepped in, broad-based ETFs saw increased volume, and all indices ultimately closed in positive territory, forming extraordinarily long lower shadows. The Shanghai Composite Index finished above the 3,800 level on higher volume, with this lower shadow echoing the one from July 20, creating a double-needle bottom pattern resembling a W-shaped base. Whether this truly forms a W-bottom requires further confirmation, but the fact that major institutional buyers appeared at this level suggests they are unwilling to let it break down for now, which is a positive signal.
