In the United States, the tense runoff elections in the state of Georgia will decide whether President Elect Joe Biden will have the majority in the Senate he needs to support his agenda or if he will face gridlock in the early stages of his term.

Results are due on Wednesday morning and analysts say Wall Street is likely set for a rally if Republicans win and a dip if Democrats gain control. Exit poll data on Tuesday suggested extremely tight contests.

"A market pullback seems both reasonable and healthy. But stocks won’t plunge to zero because there is a countervailing positive here," said Phil Orlando, Chief Equity Market Strategist, Federated Hermes of a potential Democratic sweep.

"A Biden honeymoon with Democratic Congress helmed by Nancy Pelosi and Charles Schumer would likely lead to more fiscal stimulus and infrastructure spending. That would serve as a temporary sugar high for stocks in 2021 before the bill comes due in 2022."
