A new analysis of Amazon’s market cap found that the online retail giant holds more than $2.5 trillion in cash and equivalents, and that its shares trade at a premium to its peers.

The new analysis comes amid reports of antitrust scrutiny of Amazon and other major retailers.

Shares of Amazon fell more than 2% in after-hours trading on Wednesday after the analysis.

It’s been a year since Amazon CEO Jeff Bezos announced a $3 billion dividend for shareholders.
