LIVE: Apple Q2 earnings

Apple stock hit an all-time high on Tuesday as investors anticipate a big second half of the year for the world's most valuable public company.

Although the first three months of the calendar year are typically Apple's slowest sales period, coming right after the blowout holiday quarter, Apple is still expected to report revenue growth of 5% year-on-year.

That should be a happy sign for investors after 2016 saw Apple report its first annual revenue decline since 2001.

Here's what Wall Street analysts are expecting, via Bloomberg:

• Q2 EPS (GAAP): $2.02
• Q2 revenue: $53.1 billion
• Gross margin: 38.7%
• iPhone unit sales: 51.4 million
• iPhone Average Selling Price: $666
• 3Q quarter revenue guidance: $45.7 billion
• 3Q margin guidance: 38.3%
