On CNBC's Fast Money Halftime Report, Stephanie Link said she added to her long position in Amazon.com, Inc. (NASDAQ: AMZN) after the stock traded lower on earnings.

She explained that the quarter wasn't perfect and she thinks margins were disappointing, but she is bullish because of an impressive revenue growth. North American growth was above 25 percent and international growth was 28 percent. Link understands why the stock sold off on the event, but she believes that it's going to rebound.

Josh Brown spoke about key technical levels for Amazon. He thinks $800 is going to be a key resistance. If the stock manages to trade above $800 on big volume, it can continue to trade higher.
