Amazon missed Wall Street's earnings per share estimate by more than $1.
Amazon trades down 3.38% at $1,010.63 a share after Thursday's lackluster earnings report that came after markets closed.
The e-commerce behemoth announced earnings of $0.40 a share, missing the Wall Street consensus of $1.42 by a wide margin.
However, the news wasn't all bad, as revenue spiked 25% versus last year to $38 billion. That number was given a slight boost by Amazon's AWS cloud service, which saw its revenue climb 42% to $4.1 billion.
Amazon said it thinks third-quarter revenue will come in between $39.25 billion and $41.75 billion.
Friday's selling comes just one day after Amazon CEO Jeff Bezos briefly became the world's richest person. Bezos' net worth crossed the $91 billion mark as shares rallied Thursday morning.
Shares of Amazon are up 34.1% this year.
