The S&P 500 has bounced about 25 per cent off its October lows of last year. However, the powerful rally of just a few stocks is hiding weaknesses across the board – the five largest firms (Apple, Microsoft, Amazon, Alphabet and Nvidia) have rallied over 50 per cent year to date and contributed nearly all the US benchmark’s calendar-year performance.
Other parts of the market have struggled, and domestic and global small capitalisation equities have been belted over the past 18 months.
