The 2 high-growth stocks everyone will be talking about on Friday

The stock market rose on Thursday as investors saw the bright side of the earnings season. The gains were the most marked for the Dow Jones Industrial Average (DJINDICES: ^ DJI), but the S&P 500 (SNPINDEX: ^ GSPC) was only a little late as the Nasdaq Composite (NASDAQINDEX: ^ IXIC) came with the smallest payoffs.

Earnings reports kept coming in, giving investors different perspectives on how different companies are doing. A few top growth stocks released their results today and their share prices have fallen sharply outside of business hours. Below, we’ll take a closer look at what sent e-commerce pioneer actions. Amazon.com (NASDAQ: AMZN) and disruptor of social networks Pinterest (NYSE: PIN) sharply down Thursday night.

Amazon fails

Amazon.com shares fell about 1% in the regular session. However, the stock fell more than 5% after a few hours after the release of second quarter financial results.

At first glance, Amazon’s numbers looked pretty healthy. Net sales jumped 27% in the quarter to $ 113.1 billion. Net income climbed about 50% year-over-year to $ 7.8 billion, or $ 15.12 per share. The company reported 250 million items purchased during the last Prime Day event, easily eclipsing the results of previous years.

Still, investors seemed unhappy with the size of Amazon’s gains, and they were completely unhappy with the company’s guidance for Q3. Amazon was forecasting revenue of $ 106 billion to $ 112 billion for the third quarter, which would represent a sequential decline and year-over-year gain of just 10% to 16%.

There have been concerns that Amazon will suffer as the economy reopens, and that seems consistent with what the company itself is planning. That said, Amazon has already defied naysayers, so it’s still too early to count on the e-commerce giant.

Pinterest is pinned

Meanwhile, Pinterest’s shares took a double hit on Thursday. After falling 6% in the regular session, shares of the social media company saw an even bigger drop of 16% after office hours.

Again, Pinterest’s numbers generally looked stellar on their faces. Revenue increased 125% year-over-year to $ 613 million. The company wrote off a loss a year ago with adjusted net income of $ 170 million, or $ 0.25 per share. Although user growth slowed to just 9%, average revenue per user was significantly higher, doubling in the US and internationally.

Yet Pinterest also cited an uncertain future in its directions. The social media company estimates that revenue growth will slow to around 40% in the third quarter, and it said the reduced user growth continued into July. Number of monthly active users in the United States in reality tear down in the second quarter, and these declines accelerated in July.

Investors had high expectations of Pinterest in the quarterly report, so it’s not too surprising to see the stock retreat after posting results that failed to cross the high bar. What’s important going forward is that Pinterest continues to attract new users and then monetize them more effectively to keep revenue and profits on the rise.
