Apple will hold its earning report later today, when analysts expect the company to report per-share earnings of $3.82 on revenue of $86.3 billion, per Zacks.

What we'll be watching: Here are the 3 big things we'll be paying attention to during the call.

How is iPhone X demand?

• This is the way-more-than-$64,000-question. Apple (and investors) are counting on the high-end phone to generate a "super cycle" of higher-than-typical upgrade rates and selling prices.
• Recent reports have suggested production cuts, but longtime Apple watchers know such reports have a decidedly mixed track record.

How will Apple use all that repatriated cash?

• Expect Apple to talk about buyback and dividend strategy and, if tradition is any guide, say little about its acquisition plans.
• Historically, Apple tends to say the same thing: It buys lots of little companies and, while it hasn't done a lot of big ones, isn't philosophically opposed.

Where is Apple placing its bets?

• It's hard to know just how much insight we will get, but as always, we'll be watching for any sign of where Apple is putting its time and energy.
• Though it doesn't typically comment on future stuff, there's a chance Apple could make a nod to the shift toward quality and performance that it is making for this year's big software releases.
• The company also sometimes gives oblique hints on whether to expect it to go into "new categories" or not.

Other indicators:

• Services has been the fastest growing part of Apple's business and closely watched by Wall Street.
• In the August-to-October quarter, Apple finally showed some improvement in China. It will be interesting to see how the December quarter went on that regard.
