Amazon's stock rose nearly 9.6 percent Friday after a slew of Wall Street analysts praised the e-commerce giant's first-quarter results.
At least 10 analyst firms raised their price targets on the stock. Among them was Stifel, who raised their target to $888 from $775.
"Amazon reported an impressive quarter as revenue and margins exceeded our and consensus estimates as well as surpassed the high-end of guidance," the firm said in a Friday note to clients.
In early trading, Amazon's stock traded near $660. It's opening spike added $5.1 billion to CEO Jeff Bezos' wealth. With the jump in wealth, Bezos surpassed Carlos Slim, Mexico's telecommunications tycoon, as the fourth-richest person in the world.
