'Amazon being Amazon': Wall Street rushed to the e-commerce giant's defense after weak earnings. Here's what 5 firms had to say.

Price target: Lowered to $2,150, from $2,225

Rating: Overweight

"Through one day shipping, Amazon has accelerated global retail y/y revenue growth by an average of 300bps in the past two quarters," Piper Jaffray analyst Michael Olson wrote in a note to clients on Friday.

Olson continued: "With an even more aggressive push for one day in Q4, and a 700bps easier comp (FXN global retail y/y rev growth), we believe revenue upside potential is high."

Price target: Reduced to $2,200, from $2,350

Rating: Buy

"With revenue growth accelerating for the second quarter in a row and a strong history of the company's investments in fulfillment and infrastructure driving faster growth and high returns we continue to believe AMZN represents one of the best risk/rewards in Internet," Heath Terry, an analyst at Goldman Sachs, wrote in a note to clients Friday.

Price target: $2,100

"While forward margin pressure can bring additional investor debates, AMZN's track record of ROI production against investments seems to be getting heavily discounted," UBS analysts said in a note to clients Friday.

UBS continued: "We remain Buy rated (with a $2,100 PT) and we see any post-quarter share weakness as a good entry point against the long term narratives."

Price target: Dropped to $2,200, from $2,300

Rating: Buy

"We like AMZN's strategy w/P1D as it raises the bar in e-commerce yet again & accelerates the top line, even at the expense of profitability," JPMorgan analyst Doug Anmuth wrote in a note to clients Friday.

Anmuth added: "No company we cover has earned the right to invest more than AMZN, & we'd be buying the pullback in shares."
