(Rewrites after quarterly reports)
Oct 29 (Reuters) - Alphabet rallied, Apple sank and Twitter tumbled on Thursday after a mixed bag of quarterly reports from top-tier technology companies that investors have relied on this year to power a stock market rally through the coronavirus pandemic.
Share swings following the reports from the tech heavyweights after the bell sent exchange-traded funds tracking the S&P 500 and Nasdaq down about 1% each, suggesting Wall Street may open weaker on Friday.
Mostly upbeat results from Facebook, Google-parent Alphabet and Amazon, along with Microsoft’s strong report earlier this week, show how the largest U.S. companies have expanded their businesses and outperformed smaller rivals this year as the pandemic accelerates trends toward online shopping, video streaming and other technologies.
Alphabet and Facebook both reported strong rises in advertising sales and some caution about the future. Facebook, which often is conservative with forecasts, said that pandemic-related uncertainty could make for a difficult 2021.
Facebook’s stock fell 1%, while Alphabet surged 7%.
“These results are testament to the incredible strength of the Google franchise,” said Nicholas Hyett, an equity analyst at Hargreaves Lansdown. “Where other marketing driven businesses are struggling as advertisers become more cost conscious, it seems some of the cash is in fact finding its way to the internet search giant.”
Apple fell over 5% after its iPhone sales missed estimates, although its quarterly revenue and profit beat analysts’ expectations. That wiped $100 billion from Apple’s stock market value.
Analysts expect aggregate S&P 500 earnings to drop 13% this quarter, compared to an increase of 4.5% in the tech sector, which includes Apple, Microsoft and many other of the index’s largest companies, according to IBES data from Refinitiv.
Twitter reported fewer new users than Wall Street expected, sending its shares 17% lower. If Twitter falls that much in Friday’s trading session it will have been its deepest one-day drop since March, when fear related to the pandemic sent global stock markets into a deep selloff.
Amazon reported a record quarterly profit and forecast a jump in holiday sales, but its shares fell almost 2% after it forecast a jump in costs related to COVID-19.
Thursday’s reports come amid turbulence on Wall Street, with soaring coronavirus cases and uncertainty about a fiscal relief bill in Washington dimming the outlook for an economic recovery and knocking over 3% off the S&P 500 so far this week.
Without Facebook, Apple, Amazon, Netflix and Alphabet - the so-called FAANG stocks - the S&P 500 would be down about 4% in 2020, compared with the index’s 2% year-to-date rise, according to a research note from Bespoke Investment Group on Thursday.
“Due to both the huge weight of these stocks and their outperformance, the market has become more reliant on them than ever before for its gains,” according to Bespoke.
