US equity markets tumbled, recording the worst sell-off since the early days of the COVID pandemic as a stronger-than-expected August inflation report punctured a four day rally and brought a +100 basis point interest rate hike into play next week - Dow dropped -1,276-points or -3.94%, with all 30 index components settling in the red. The broader S&P500 shed -4.32%, with Communication Services (down -5.64%), Information Technology (-5.36%) and Consumer Discretionary (-5.22%) falling over >5% and leading all eleven primary sectors lower. The S&P500 Growth Index fell -5.19%, while the S&P500 Value Index declined a more modest -3.49%. Just six (6) stocks in the S&P 500 finished in positive territory, including Twitter Inc (up +0.80%) after shareholders voted to approve Tesla Inc (-4.04%) Chief Executive Elon Musk's US$44B bid to acquire the embattled company and take it private. Citigroup Inc (down -3.38%) Chief Financial Officer (CFO) Mark Mason warned the fees his bank collects from deal making and capital markets origination are likely to tumble -50%, in line with the broader slowdown hitting Wall Street. That mirrors earlier comments from JPMorgan Chase & Co (-3.47%), which said investment-banking fees may fall by half as clients stay on the sidelines. The five largest companies in the S&P 500 by market capitalization - Apple Inc (down -5.87%), Microsoft Corp (-5.50%), Amazon.com Inc (-7.06%), Google parent Alphabet Inc (-5.90%), and Tesla Inc - shed -US$477B in value. The Nasdaq slumped -5.16%, with Meta Platforms Inc (-9.37%) and Nvidia Corp (-9.47%) also falling sharply. All components in the Nasdaq 100 (down -5.54%) declined. The latest declines marked the biggest daily percentage fall for all three benchmark indexes since 11 June, 2020, according to Dow Jones Market Data. The small capitalisation Russell 2000 lost -3.91%.
