NEW YORK: Wall Street ended the session in positive territory and the dollar dipped to its lowest in more than two years on Wednesday, the penultimate trading day in a remarkable year of pandemic, recession and recovery.
All three major U.S. stock indexes gained modestly, but short of all-time closing highs as recently enacted coronavirus relief and the ongoing rollout of COVID-19 vaccines fed optimism over economic recovery in 2021.
"It is light action today," said JJ Kinahan, chief market strategist at TD Ameritrade in Chicago. "It's a little bit of 'Hey, we are going to finish the year strong,' everybody feels good and we will see what happens come January 4."
"But at some point we are going to start to have volatility again related to COVID," Kinahan added. "This is not a story that is going away in the first six months of 2021."
That sentiment was shared by Matthew Keator, managing partner in the Keator Group, a wealth management firm in Lenox, Massachusetts.
"My anticipation is that (the economic rebound) will probably be more robust in the latter part of 2021," Keator said. "Once there's the sense of an all-clear sign, we would anticipate a robust response from the consumer," Keator added.
Britain approved a coronavirus vaccine developed by Oxford University and AstraZeneca in the latest development in the rapid progression, testing, approval and deployment of drugs to battle the disease.
