Even with this week's weakness, Amazon.com stock has been outperforming the retailers whose businesses it's challenging, and on the eve of its earnings, it would be fair to assume Amazon will have a fairly volatile trading day after it reports.
Amazon has a history, in the last 10 years, of beating earnings-per-share estimates just slightly more than it misses, but the stock is very volatile after earnings days, averaging a 9.5 percent move either way, according to Bespoke. The company has reported revenue beats at a greater rate of 66.8 percent, versus the 56.4 percent beats on earnings per share.
The company reports after Thursday's closing bell, and is expected to have a loss of 15 cents per share on revenue of $19.34 billion, according to Thomson Reuters. That revenue would be 23 percent higher than the $15.70 billion in last year's second quarter. The company had a loss of 2 cents per share in that quarter a year ago.
