Amazon fell into bear market territory on Friday and dropped below $800 billion in market value.
The stock ended the trading day at $1,626.23 per share, falling at least 20 percent below its 52-week/intraday all-time high of $2,050.50. The stock had previously entered bear market territory in December. At one point last year, the stock hit $1 trillion in market value during intraday trading.
Shares fell 5.4 percent Friday after the company announced on a call with investors Thursday that it would likely increase investment in 2019 and raised concerns about new regulation in India.
Amazon's stock initially popped in after-hours trading on its fourth-quarter 2018 earnings report Thursday. The stock took a steep turn during the company's call with analysts when Amazon CFO Brian Olsavsky said Amazon plans to increase investments this year after scaling back capital expenditures and hiring the year prior.
