Amazon back to $1 trillion valuation after 7-day streak

Amazon.com Inc. is teasing with a $1 trillion valuation again after posting its longest winning streak since briefly surpassing that level in September.

Seven consecutive days of gains have boosted the e-commerce giants market value to $993 billion as of Wednesdays close, according to data compiled by Bloomberg. A gain of less than 1% for the stock would push the market capitalization above the 10-figure mark.

Amazon has added about $119 billion in market value since the end of May. Nearly half of those gains have come in the past seven days, which comprises Amazons longest string of advances since September 4.
