P/E isn't an appropriate measure for a highly leveraged retail operation with thin margins. Little things can cause profits to soar (and plunge). 1% movement in margin is $250 million.
The truth is, management has only a vague idea of where final profits (or loss) will be for the full year and they don't manage the business in that fashion. EBITDA, required investment outlays and debt maturities are what management follows and that is what investors should follow too.
