The Brexit slowdown has arrived. Data released by the Office for National Statistics on Friday showed the UK's economy grew at a 0.3% clip in the first quarter, making for the slowest growth since the first quarter of 2016.

Amazon crushes earnings. The online retailer earned an adjusted $1.48 a share, easily beating the Wall Street estimate of $1.13.

Alphabet beats. Google's parent company earned $7.73 per share as revenue surged 22% versus a year ago to $24.75 billion. The average cost-per click sank 19% YoY, making for the biggest drop since at least 2014.

Starbucks same-store sales miss. The coffee giant said sales at stores open at least a year rose 3% in the first quarter, missing the 3.6% gain that analysts were anticipating.

Cloudera is going public.
