US Stock Market Performance: The US stock market rebounded from initial losses due to a criminal investigation into Federal Reserve Chairman Jerome Powell, with the DJIA and S&P 500 both reaching record highs.
Walmart's Impact: Walmart's inclusion in the Nasdaq 100 contributed to the DJIA's recovery, which initially dropped over 490 points but closed up 86 points at 49,590.
Alphabet's Milestone: Alphabet's stock rose over 1%, reaching a record high and making it the fourth US company to achieve a market cap of $4 trillion, partly due to its partnership with Apple for AI development.
Building Permits Data: The preliminary data for building permits in the US showed a month-over-month decrease of 0.2% for September, an improvement from the previous decline of 2.3%.
