The US market has had a stunning run over the past year or so. The S&P 500 index peaked in January 2022, before declining 25.4 per cent over the following nine months in the wake of rapidly increasing interest rates. Since those October 2022 lows, the market has rebounded 40.5 per cent. In recent weeks it’s surpassed the peak from two years ago, moving past 5000 points for the first time. Against that backdrop, is it too late to invest in US stocks?
