【TOP1 Morning】Vaccine effect retreat. Oil prices and stock market suffer while gold continues to rise
The discovery of a variant of the new crown virus in the UK has prompted many countries to close their borders to the UK; drugmakers are busy testing the effects of the new crown vaccine on the new strain.

Gold: Gold prices rose slightly on Wednesday.
Spot gold rose 0.2% to US$1,863.83 per ounce, while US gold futures fell 0.1% to US$1,868.10.
Due to poor US consumption and housing data, the authorities have introduced further stimulus measures to support the expected rise of economic recovery.
Forex: The US dollar rose in quiet trading on Tuesday.
Concerns about the lockdown and travel restrictions caused by the mutated new coronavirus in the UK have weakened people's optimism that the US Congress passed a stimulus bill last night.
The dollar index rose 0.6% to 90.675, and the euro fell 0.7% to 1.2156 dollars. The dollar rose 0.4% against the yen to 103.70 yen.
Currencies associated with higher risk appetite, such as the Australian dollar and New Zealand dollar, also weakened against the US dollar.
The market had prepared for a weaker dollar earlier. The recovery after the market digests the pandemic will push up commodity prices and benefit exporting countries and their currencies, while the dollar will fall.
"I still think the U.S. dollar will still face significant pressure in the first half of next year. The valuation and pricing of some U.S. stocks are too high," said Ronald Simpson, managing director of Action Economics' global currency market analysis department.
Crude oil: Oil prices fell to $50 a barrel on Tuesday.
Oil prices expanded the previous trading day's decline as the emergence of the new crown virus in the UK renewed concerns about demand recovery.
Brent crude oil futures fell more than 1.63% to settle at US$50.08 per barrel, while US crude oil futures fell more than 1.98% to US$47.02.
Both contracts fell nearly 3% on Monday, partially reversing the recent gains caused by the launch of the new crown vaccine.
The recent rise in oil prices caused Brent crude oil futures to hit a high of $52.48 last Friday since March. But under the fear of the spread of the virus, oil prices have since fallen. Some people believe that it may fall further.
Stock market: The Dow recorded its biggest one-day drop this month.
The S&P 500 index closed lower for the third consecutive day, but the Nasdaq still set a record closing high as Apple's stock price jumped. Apple made cars hit Tesla's stock, vaccine stock Moderna plunged 9%.
Investors are still worried about the new crown epidemic in the United States and Europe, even if the vaccine has already been distributed and the US Congress has voted to pass a new round of fiscal stimulus.
The Dow Jones Industrial Average closed down 200.94 points, or 0.67%, to 30015.51; the S&P 500 index fell 7.66 points, or 0.21%, to 3,687.26 points; the Nasdaq closed up 65.40 points, or 0.51%, to 1,2807.92 points.
