|About: American Airlines Group (AAL)|By:, SA News Editor

Wolfe Research has an interesting observation on American Airlines Group (AAL +1.1%) that could give investors a reason to buy the stock.

Analysts with the boutique investment note that the 2015 consensus EPS estimates on American, which feel "light" to them for starters, have risen faster this year than the carrier's stock price, 63% vs. 56%.

The differential is the biggest that Wolfe found in the sector.
