Alphabet shares hit all-time high as Pixel phones land some positive reviews
Members of the media examine Google's Pixel phone during an event to introduce Google hardware products on October 4, 2016 in San Francisco, California.

Shares of Google parent Alphabet jumped nearly 2 percent on Tuesday, after many outlets gave generally positive reviews for the company's upcoming smartphone, the "Pixel."

With the pop, both Alphabet's Class A and Class C shares closed at all-time highs, at $821.49 and $795.26, respectively. The 1.82 percent rise for Class A shares marked their best day since July 29.

The reviews gave consumers and investors a peek at Google's first line of in-house designed smartphones, which made a splash when they were unveiled earlier this month at an event. With the largest Android maker, Samsung , still recuperating from problems with their Galaxy Note 7 catching fire, Google's Pixel could be a compelling competitor against Apple's iPhone 7 and an alternative for Android loyalists.



While some reviewers were disappointed with the photo quality and battery life, many raved about the camera and artificial intelligence software installed on the smartphone.

Walt Mossberg from The Verge boasted that "the Pixel is easily the best Android phone I've ever tested."

The Pixel will be available for consumers in-store and shipped out by Thursday.
