Here's how Apple's iPhone X event is impacting other stocks

Apple revealed, among other things, its iPhone X on Tuesday.

In a presentation that lasted nearly two hours, the company announced three new iPhones, a set top box, a watch and other company initiatives.

Apple’s stock is down about 2.5% since the event, but other companies are moving on the news too.

Some of those companies were mentioned by name, like Snap or Dolby, while others are expected to be suppliers for the new iPhone.

With a market cap of around $US833.87 billion, Apple is a company with considerable clout, and one mention in its biggest event of the year can make waves for smaller companies.

Read below to find out which companies have moved, and how much they have moved since the beginning on Tuesday.

Apple (AAPL)

Stock move: -2.59%
