Part of the gains came from the latest inflation data. The consumer price index (CPI) in February increased by 3.2% year-on-year and 0.4% month-on-month. Market expectations were 3.1% and 0.4% respectively. The data was lower than many investors feared, boosting the market. Part of the rally may also come from optimism brought about by the upcoming Nvidia 2024 GTC conference.
