SEATTLE — Amazon.com’s market value has climbed $23 billion this week in the wake of positive analyst reports that point to continued growth for the world’s dominant online retailer.
Amazon shares closed up 1.2 percent at a record $886.54 Friday, and were up 5.8 percent from Monday’s opening price.
Amazon, the fourth-largest publicly traded company, is now worth about $423 billion.
The rise in market valuation caps a busy week for the company, which on Tuesday won a bidding war for Souq.com, a large e-commerce company based in Dubai and focused on the Arab world.
The same day it opened two grocery pick-up locations in Seattle. And on Wednesday Amazon closed Quidsi, a former rival it had acquired in 2011 but failed to turn profitable.
