After a nice breakout to new all-time highs, I believe Wal-Mart could easily be setting up as a quick short.
On the daily chart, below, note the blue lines indicating a tight range of late below the the 20-day simple moving average. On weakness, WMT is likely to breakdown further and at least test its 50-day moving average. A move over $85, alternatively, would be a long trigger.
A few short ideas into weakness: AAL COST DAL LOW UAL V
Long ides into strength: BLMN CORN RUBI
