Apple's enormous cash hoard grew to $237.6 billion in the fiscal fourth quarter, up $6.1 billion from the previous quarter.

If the company's massive cash pile was its own company, it would be the seventh largest in the S&P 500 and the fourteenth largest public company in the world.

The tech giant reported earnings that beat Wall Street expectations on Tuesday, and sold more iPhones than expected. The stock briefly jumped after hours before settling down 2 percent.
