Apple missed analysts' forecasts in results released after markets closed on Friday (NZT), as chip shortages and factory disruptions because of the coronavirus pandemic hit production.
Microsoft and Apple have vied for the position of the most highly valued public company since the iPhone maker first overtook its tech rival in 2010, retaining its position until 2018.
Microsoft last rallied back above Apple in the midst of the pandemic-induced sell-off in 2020. Its stock has risen more than 7 per cent since the start of the week, taking its year-to-date gains to almost 50 per cent.
Another tech giant, Amazon, fell 2.2 per cent yesterday (NZT) after warning that rising costs because of labour shortages would crimp its earnings for the rest of the year. The ecommerce giant is valued at $1.7tn and ranks as the fourth-largest company by market capitalisation, behind Google's parent Alphabet.
The disappointing updates contrasted with several other major tech groups such as Alphabet that reported earlier in the week, whose strong results helped the tech-heavy Nasdaq Composite catch up with wider equity markets and surpass its record high hit in early September.
The Nasdaq Composite rallied back from early losses yesterday (NZT), rising 0.3 per cent and finishing the week 2.7 per cent higher.
Nonetheless, its weaker performance this year is indicative of a shift by investors away from technology stocks, which had led the market higher, and towards more cyclical companies set to benefit from economic recovery.
Tech stocks were the worst performing sector in the S&P 500 in the first quarter, as expectations of a reopening trade pegged to companies beaten down by the pandemic took hold. As exuberance faded in the second quarter, tech stocks roared back to lead gains, before slipping again to give way to financial stocks and communication companies in the third quarter.
