WMT is offering a great entry for the long term here. Free cash flow yield of 6.8%, earnings yield of 5.6% with very low debt, with a 2.94% dividend yield on top make for a solid spot to acquire WMT shares.
You can buy here, or buy gradually over a week/month to average your entry.
I'd reccomend either risking a 3.1usd decline, or using no stop and sizing it...
