NEW YORK, Sept 25 (Reuters) - Stocks were set to fall more than 2% this week and the dollar was on track for its strongest week since April as concern over the economic effect of a second wave of virus-related lockdowns continued to weigh on investors’ risk appetite.
But tech stocks led the way higher on Wall Street on Friday, as they have of late on days governed by worries over the economic recovery. The gains offset losses elsewhere, and an index of major stock markets globally was up on the day.
Other than COVID-19 angst, the week was dominated by speculation over the likelihood of another stimulus package to support the American economy.
“There’s evidence of a slowdown in the United States, which we think is temporary, but it would be reinforced if there is no additional fiscal package,” said Sebastien Galy, senior macro strategist at Nordea Asset Management.
Bets on more stimulus increased after squabbling U.S. political parties talked about another super-sized stimulus package, but the rise in the dollar and demand for safe-haven government bonds remained telling.
On Wall Street, the Dow Jones Industrial Average rose 265.95 points, or 0.99%, to 27,081.39, the S&P 500 gained 41.35 points, or 1.27%, to 3,287.94 and the Nasdaq Composite added 197.92 points, or 1.85%, to 10,870.19.
The S&P was on track for four consecutive weekly losses, the longest such streak in over a year.
The pan-European STOXX 600 index lost 0.10% and MSCI’s gauge of stocks across the globe gained 0.84%. The global index was down over 2% for the week.
Emerging market stocks lost 0.03%. MSCI’s broadest index of Asia-Pacific shares outside Japan closed 0.38% higher, while Japan’s Nikkei rose 0.51% to end a three-day week.
Treasury yields remained little changed in a week where the 10-year traded in a 5-basis-point range.
“Overall the market remains fairly range-bound. There is some intraday, intra-week volatility that when you really look at it, we just don’t go anywhere,” said Justin Lederer, an interest rate strategist at Cantor Fitzgerald.
But the relapse in sentiment has hit emerging market debt, especially countries with weak credit ratings. Argentina’s newly restructured bonds have lost around 25%, making it the worst return to markets since Greece in 2012, while plenty of other countries have seen 10% slides.
China’s government bonds gained acceptance into one of the world’s most coveted bond benchmarks, the FTSE Russell WGBI. CGBs will be introduced late next year.
In the currency markets, the dollar index climbed for the fourth time this week and was set for its strongest weekly showing since April.
The dollar index rose 0.314% on Friday, with the euro down 0.38% to $1.1628.
The Japanese yen weakened 0.18% versus the greenback at 105.59 per dollar, while sterling was last trading at $1.2732, down 0.13% on the day.
Demand for the greenback was boosted in part by Washington’s failure to create a stimulus package and concerns ahead of the U.S. election, according to Juan Perez, senior currency trader and strategist at Tempus Inc.
“In times like that the chaos and havoc and blurriness of the future is so intense and so dense, that’s when the dollar is going to rise once again,” said Perez.
The Russian rouble sank to a near six-month low against the dollar. Geopolitical concerns further weighed on Russian assets with the threat of sanctions over the poisoning of Kremlin critic Alexei Navalny, in which Moscow denies wrongdoing. The crisis in neighboring Belarus also continued to linger.
The rouble lost 1.10% versus the U.S. dollar at 78.17.
The dollar’s strength this week has also battered commodities, with gold set for its biggest weekly drop in six. On Friday, spot gold dropped 0.2% to $1,864.96 an ounce.
Silver tumbled 14% this week so far, a drop not seen in over six months. The spot price fell 0.58% to $23.07 on the day.
Oil prices fell and were set for a weekly decline mostly due to mounting worries about the impact on fuel demand of a widespread resurgence in coronavirus infections.
U.S. crude recently fell 0.02% to $40.30 per barrel and Brent was at $41.94, flat on the day.
