Companies to watch: Tilray under pressure, problems for The RealReal, Amazon senses fear

Here are the companies the Yahoo Finance team is watching for you today.

Investors are putting some pressure on Tilray (TLRY). Revenue beat forecasts last quarter, but the cannabis company reported a wider-than-expected loss. Meanwhile, the CEO says Tilray is working on new deals to boost the available supply of cannabis in Canada.

We saw a similar story at online consignment shop The RealReal (REAL). It reported a revenue beat and a smaller-than-expected loss. Shares of The RealReal have sunk more than 40% since the company went public back in June.

As if Amazon (AMZN) didn't already know enough about you. Its facial recognition software now can sense fear! The e-commerce giant says the software, called Rekognition, can accurately identify seven different emotions, based on your expression. Amazon has faced plenty of controversy over the use of the software by law enforcement.

The FAA is taking precautions against Apple (AAPL). U.S. airline safety regulators have banned certain MacBook Pro laptops on flights after Apple recalled its batteries because they posed a fire hazard. The laptops at risk are some 15-inch MacBook Pros sold between September 2015 and February 2017. These laptops join the list of singled out devices that are banned on airplanes, like the Samsung Galaxy Note 7.

Twitter (TWTR) users will have to wait a while longer before they see an edit button — a long-awaited feature to help fix simple mistakes without deleting an entire tweet. At a recent press event, a Twitter executive said the feature is likely something the social media giant will work on in the future, but an edit button is "not anywhere near the top of our priorities."

Correction: An originally published version of this article stated that the RealReal reported a wider loss than was expected. The error has been corrected.
