The Huoxing Finance report states that on November 7, Thursday, the Philadelphia Semiconductor Index (SOX) fell 12%, while the S&P 500 dropped 4%, marking the second-worst single-day performance for SOX since its inception (the worst occurred in March 2020 at the onset of the COVID-19 pandemic, and the third-worst during the dot-com bubble). However, the selling pressure did not persist on Friday, as the index strongly rebounded by over 4%. Market sentiment is expected to further recover over the weekend. Historical data from Deutsche Bank shows that, in the 3 months and 12 months following the 9 worst trading days for SOX, the average returns were +23.3% and +48.8% respectively, with positive returns recorded in 6 out of the 9 instances, indicating that significant rebounds often follow such extreme selling pressure.
