A Facebook rally pushed shares of the social media company to a record on Wednesday.
Facebook rose as much as 6% to US$230.33, extending a winning streak to the fifth consecutive day.
Facebook’s previous closing high was on 29 January 29 at $223.23.
The latest optimism came from e-commerce updates Facebook unveiled on Tuesday, which analysts expect will help accelerate revenue growth.
As of Wednesday’s US market close, Facebook had a market capitalisation of $655-billion; Amazon’s was nearly $1.25-trillion.
