NEW YORK (REUTERS) - Wall Street rallied on Friday (April 24), led higher by Apple and Microsoft as investors finished a turbulent week of trading and some states prepared to relax coronavirus-related lockdowns.

Apple and Microsoft each climbed more than 1 per cent, lifting the S&P 500 more than any other companies. The two tech titans are on tap to report their March-quarter results next week, giving investors a glimpse at how the pandemic has affected their global businesses.

Boeing Co tumbled more than 6 per cent after a report the plane maker was planning to cut 787 Dreamliner output by about half. All of the 11 S&P 500 sector indexes moved up, with information technology jumping 2.1 per cent and materials rallying 1.5 per cent.

Even with Friday's gains, the S&P 500 ended the week lower, with investors fearful of a deep economic slump following a near-crash in April business activity and weekly jobless claims topping 26 million in five weeks.

The index has recovered more than 25 per cent from its March low and expectations are growing that more businesses will be allowed to reopen as coronavirus infections showed signs of peaking.

Georgia became the first state to push ahead with its plan to allow an array of small businesses to reopen on Friday despite disapproval from President Donald Trump and health experts.

Investors may be overestimating how quickly US businesses can go back to normal, and the S&P 500 could fall 5 per cent or more as it becomes evident that resuming normal economic activity may not happen for months, warned Mr Eric Freedman, chief investment officer at US Bank Wealth Management in North Carolina. "We think this is likely to be a little bit of a sideways market, and we won't be surprised to see a bit of downside before we see more upside," Mr Freedman said.

Overall, analysts still expect a 15 per cent decline in S&P 500 first-quarter earnings, with profits for the energy sector estimated to slump more than 60 per cent, raising fears of debt defaults, layoffs and possible bankruptcies.

New orders for key US-made capital goods unexpectedly rose in March, but the gains are not likely to be sustainable amid the pandemic, which has abruptly shut down the economy and contributed to a collapse in crude oil prices.

The CBOE volatility index, known as Wall Street's fear gauge, was down for the third straight session.

Amazon rose 0.4 per cent to a record high close ahead of its quarterly report on Thursday. With online shopping booming as people avoid traditional stores, Amazon's stock market value has ballooned by over US$100 billion (S$142 billion) since Feb 19, just before coronavirus fears gripped Wall Street.

The Dow Jones Industrial Average jumped 1.11 per cent to end at 23,775.27 points, while the S&P 500 gained 1.39 per cent to 2,836.74. The Nasdaq Composite added 1.65 per cent to 8,634.52. For the week, the S&P 500 fell 1.3 per cent, the Dow lost 1.9 per cent and the Nasdaq lost 0.2 per cent.

Advancing issues outnumbered declining ones on the NYSE by a 1.65-to-1 ratio; on Nasdaq, a 2.00-to-1 ratio favoured advancers. The S&P 500 posted one new 52-week high and one new low; the Nasdaq Composite recorded 35 new highs and 14 new lows.

Volume on US exchanges was 10.2 billion shares, compared with a 12.5 billion-share average over the last 20 trading days.
