U.S. shoppers spent $35.27 billion online overall during Cyber Week, the period from Thanksgiving through Cyber Monday.
But the modest pickup trounced the paltry 2.9% increase in sales during China's Singles Day, an 11-day shopping festival ending November 11, hosted by Alibaba and other Chinese e-commerce firms.
Originally, Singles Day was an unofficial Chinese holiday on Nov. 11 (11/11) to celebrate people who were not in relationships.
These days, brands use Singles Day to clear inventory and experiment with new products.
With the COVID-19 pandemic still raging in China, "it wont be fair to can compare" Singles Day with Cyber Week, Chernev said, as Americans are shopping with fewer restrictions.
