Dropbox hits the scene, Nike bounces back, Micron beats big, Amazon reportedly gets special drone patent

Here’s a look at some of the companies the Yahoo Finance team will be watching for you.

Dropbox (DBX) tops our list. The cloud storage site goes public today. The stock was priced above its range at $21 a share. Dropbox is another highly anticipated unicorn IPO. It will trade on the Nasdaq in one of the largest tech stock offerings of the year.

Nike (NKE) is on the move. The stock is up sharply after posting Q3 earnings and revenue that beat expectations. Most notably, CEO Mark Parker said the slumping sales trend in the U.S. is finally reversing thanks to experiential shopping and new product issues throughout the company.

Micron (MU) is taking a huge hit today. Even after beating big on second quarter earnings, investors sold after Micron admitted an issue at one of its Taiwan plants forced it to halt production there. According to the website SiliconANGLE, production is expected to take a hit in Q3, bringing down revenue by about 2%. Despite this, Micron’s forecast still surpassed Street estimates.

Amazon (AMZN) was just granted a patent for, get this, drones that can react to screaming and flailing arms. The Washington Post reports Amazon’s delivery drones will detect gestures like a welcoming thumbs up, shouting or frantic arm waving. After reading the signs, the drone will then decide to release the package or abort the delivery mission.
