Wall Street’s main indexes have ended higher to snap a three-session losing skid as investors jumped back in to take advantage of the pullback in technology-related stocks, a day after the Nasdaq confirmed correction territory.

Tesla Inc shares rebounded 10.92 per cent after suffering their biggest one-day percentage drop in the prior session while Apple Inc, Microsoft Corp and Amazon.com Inc – the top three US public companies by market capitalisation – each rose by at least 3.0 per cent.

Other stay-at-home winners such as Facebook Inc and Google-parent Alphabet Inc also climbed, a day after the tech-heavy Nasdaq ended 10 per cent below its September 2 record closing high, commonly known as a correction.

The S&P tech sector notched its biggest one-day percentage gain since April 29.

“It’s certainly a massive, surprising rebound,” said Jack Ablin, chief investment officer at Cresset Capital Management in Chicago.

“On one level it looks speculative but on another it is almost defensive because we know these companies will survive no matter what COVID throws at us.”

Analysts also said the Nasdaq’s ability to hold its 50-day moving average, a technical support level, was key in reversing the market’s direction.

The Dow Jones Industrial Average rose 439.58 points, or 1.6 per cent, to close at 27,940.47, the S&P 500 gained 67.12 points, or 2.01 per cent, to 3,398.96 and the Nasdaq Composite added 293.87 points, or 2.71 per cent, to 11,141.56.

The percentage gains marked the best one-day performance for the S&P since June 5, the Nasdaq since April 29 and the Dow since July 14.

US stocks have become susceptible to volatility as market leadership has narrowed during the year to a handful of heavyweight tech-related stocks as traders bid up their shares in a rally that triggered a Nasdaq-led rebound for Wall Street from its pandemic lows in March.

The recent pullback has also been driven by worries that sellers of call options would unwind massive amounts of stocks they bought as hedges during the rally.

Media reports last week said SoftBank Group Corp has made big bets on equity derivatives tied to tech firms.

In a sign of growing unease about the positioning in tech stocks, skew, a measure of demand for protective put options in relation to call options, has risen sharply.

Market volatility is expected to further increase in the run-up to the US presidential election, with September and October also historically turbulent months of the year.

In a reversal from the prior three sessions, growth stocks jumped 2.59 per cent to outperform the 1.13 per cent climb in value stocks.

Market participants were watching for signs of a widening in market breadth, supported by improving economic data.

AstraZeneca Plc could resume trials for its experimental coronavirus vaccine next week, the Financial Times reported, after the British drug maker paused global trials of its experimental COVID-19 vaccine.

Still, its US-listed shares fell 1.96 per cent.

Tiffany & Co tumbled 6.44 per cent after French luxury goods giant LVMH warned it was set to walk away from its planned $US16 billion ($A22 billion) takeover of the US jeweller.

Advancing issues outnumbered declining ones on the NYSE by a 2.98-to-1 ratio; on Nasdaq, a 2.27-to-1 ratio favoured advancers.

The S&P 500 posted 3 new 52-week highs and 2 new lows; the Nasdaq Composite recorded 31 new highs and 25 new lows.

About 8.91 billion shares changed hands in US exchanges, compared with the 9.21 billion daily average over the last 20 sessions.
