It was a challenging end to the week on Wall Street, with the growth-heavy Nasdaq index falling 4.2% on Friday, its biggest daily decline since April last year. The S&P 500 index in the US fell 2.6% for the week, breaking a nine-week winning streak. Looking ahead, US inflation will be in the spotlight this week, with the CPI and PPI both due for release. These will come ahead of next week's Federal Reserve meeting, the first under new Chair Kevin Warsh.
