What happened

Amazon (AMZN 2.50%) stock sank roughly 23.8% in April, according to data from S&P Global Market Intelligence. The tech giant's share price moved amid bearish market momentum through much of the month and then saw a dramatic sell-off following the publication of its first-quarter earnings results.

Amazon published Q1 results after the market closed on April 28, delivering results that came in significantly worse than expected. The company posted a loss per share of $7.56 on revenue of $116.4 billion. Sales for the period fell just short of the average analyst estimate, but the average analyst estimate had actually targeted per-share earnings of $8.36 for the period.

So what

Amazon's investment in electric vehicle (EV) company Rivian was to blame for its net loss in Q1. The EV specialist's share price has fallen precipitously in recent months, forcing Amazon to adjust the value on its books. The e-commerce and cloud computing leader posted an operating profit of $3.7 billion in the period, but this was still far below the $8.9 billion in operating income it posted in the prior-year quarter. 

While overall revenue climbed 7% year over year, the Amazon's results were uneven among segments. Amazon Web Services (AWS) continued to serve up impressive performance and grew sales roughly 36.5% year over year to reach $18.44 billion in sales, and the unit posted an excellent 35.3% operating margin. Sales for the company's international segment, which primarily consists of its online retail business in the region, fell roughly 6% year over year to come in at $28.8 billion. Meanwhile, advertising revenue grew 25% to reach roughly $7.9 billion but fell short of the $8.2 billion in sales targeted by the average analyst estimate.

Now what

Amazon's e-commerce business boomed amid pandemic-driven social-distancing conditions, but it's now seeing that demand catalyst soften. The company is also facing headwinds due to inflation and high shipping costs. 

For the second quarter, Amazon is guiding for revenue to be between $116 billion and $121 billion. This target came in significantly below the $125.17 billion in revenue called for by the previous average analyst estimate. The company also guided for operating performance between a loss of $1 billion and income of $3 billion -- a stark shift from the $7.7 billion in operating profit it posted in last year's quarter.

While Amazon's guidance for the current quarter was disappointing, the sell-off for its stock appears overdone. AWS remains incredibly strong, and the company's e-commerce business should deliver strong growth over the long term even though its current performance is disappointing the market. With shares down roughly 35% from the high they hit last year, Amazon stock looks like a strong buy.
