Equities rebound after three-session Nasdaq sell-off

NEW YORK (Reuters) - Global equity benchmarks rebounded and the dollar dipped on Wednesday following a sharp sell-off in U.S. tech stocks that had erased more than 10% from the Nasdaq Composite Index in three days.

The news unnerved investors in Asia hoping for the quick introduction of a vaccine that would accelerate the global economic recovery from the pandemic.

“This has been a correction that was probably not that surprising, given the move in August in the tech sector,” said Salman Baig, an investment manager at Unigestion, adding that the outlook for Big Tech was positive.

“It’s exactly those companies that are new economy - they are benefiting because of their model, the industry, the virus,” he said.

Those attributes have sparked heavy bets from the likes of SoftBank, which has traded heavily in tech stocks call options.

The bets have made investors worried about exposure to tech the sector. SoftBank Group 9984.T shares lost 3% in Tokyo, extending a slump this week that has wiped $15 billion from its market capitalization.

MSCI's gauge of stocks across the globe .MIWD00000PUS gained 1.47% following broad declines in Asia and rallies in Europe.

On Wall Street, the Dow Jones Industrial Average .DJI rose 439.58 points, or 1.6%, to 27,940.47, the S&P 500 .SPX gained 67.12 points, or 2.01%, to 3,398.96, and the Nasdaq Composite .IXIC added 293.87 points, or 2.71%, to 11,141.56.

Despite renewed appetite for stocks, yields on safe-haven German government bonds DE10IT10=RR fell to their lowest levels in two-weeks. The fall in tech shares also boosted demand for U.S. Treasuries, even though heavy supply this week is expected to weigh on the bonds.

Benchmark 10-year notes US10YT=RR last fell 4/32 in price to yield 0.6951%, from 0.684% late on Tuesday.

The dollar index =USD fell 0.325%, with the euro EUR= up 0.23% to $1.1806.

The remarkable rally in global shares from their March lows has been driven in part by expectations that a COVID-19 vaccine would be found.

AstraZeneca’s suspension of global trials dims prospects for an early rollout of its vaccine, described by the World Health Organization as probably the world’s leading candidate and the most advanced in terms of development.

Deutsche Bank strategists called the suspension of the trials “a blow.”
