During the current streak, which included five-straight record closes, the stock had run up $149.97, or 8.9%, over the past nine sessions, to add about $72.8 billion to the e-commerce giant’s market capitalization. Amazon’s market cap at Tuesday’s close was $894.7 billion, to rank second in the U.S. behind Apple Inc.’s $941.0 billion. Amazon shares have shot up 57% year to date through Tuesday, while Apple’s stock has climbed 13% and the S&P 500 has gained 5.1%.
