Two numbers could drive Apple (NASDAQ:AAPL) stock when the company reports earnings on Oct. 28, Fool contributor Tim Beyers says in the following video.

The keys are in iPhones and iPads, Tim says. Analysts are likely to have high hopes for handset sales. After all, the Apple moved 9 million iPhone 5s and 5c models during their first weekend on sale. Apple sold 26.9 million iPhones in last year's fiscal fourth quarter.

Investors shouldn't hope for nearly as much growth on the iPad side of the ledger, Tim says. Wall Street appears to be modeling for no more than 15 million Apple tablets sold in the quarter, a modest improvement over last year's 14 million.

That won't be a problem so long as iPhone sales show substantial year-over-year growth. And if they don't? Can Apple stock still rally? Tim addresses that question and more in the video. Please watch now and then leave a comment to let us know what you think.
