Amazon boxes are seen stacked for delivery in New York City.

Amazon.com said Wednesday it may buy back up to $5 billion in stock over the coming years.

Shares rose more than 2 percent in after-hours trading on the news. The company said the program does not have a set expiration time.

Amazon said this buyback would replace a $2 billion authorization from 2010.

As of Dec. 31 it had used just $1.24 billion of that prior program.

The new buyback comes amid weakness in the stock, with shares down 28 percent from their recent high on Dec. 29.
