Last week: Performance
Seven of eleven sectors were higher last week, but it didn’t matter for the major indexes as the worst weekly loss for technology since April 2025 dragged the S&P 500 to a 1.95% loss. EM was even worse, as the tech/chip collapse started in South Korea and extended into Taiwan.
Last week: The most important moves

Korea’s collapse kicks off again
Worst week for the KOSPI since 2008. I called out the risk to SK Hynix in the October 8 Stock Trends, and it has been straight down since.
