No. 1 online bookseller Amazon.com will be included in the Nasdaq 100 Index. Its stock spiked following the news today, hitting a 52-week high.

The firm will be added to the Nasdaq 100 Index on December 21.

Seattle-based Amazon's stock was up 20.5 today after the bell, closing at 242.75 a share. The stock blew past its previous 52-week high of 233.125.
