Amazon profit jumps while revenue misses mark

Amazon reported on Thursday that profit in the final three months of last year leapt, but saw shares sink as revenue for the tech giant fell shy of expectations. While revenue rose to $43.7 billion from $35.7 billion in a similar year-over-year comparison, Wall Street had expected Amazon to take in more cash during the key holiday shopping season. Amazon shares were down more than four percent to $804.75 in after-market trades that followed release of the earnings report.
