On CAPS, 41% of the 937 members who have rated Delta believe the stock will underperform the S&P 500 going forward.

Just last month, one of those Fools, gameguru, succinctly summed up the Delta bear case for our community:

The recent run-up seems unsupported by fundamentals. Oil prices likely can and will go higher. TSA delays and FAA furloughs may reduce traffic. Recent weather problems will hurt traffic. Delta continues trying to expand its already expansive routes, which is usually a recipe for capital loss in this space.
