Wal-Mart made their high in 2015 and ever since it's going down. More problems will surface with this company as more days pass by. But there are only 3 Green support lines @ work 1997, 1987, 1982. Probably the next good support is area of $50-$45. Then when it breaks it is possible to re-visit $5 area for ultimate buy zone. With the time line analysis it may take some time to plunge around 2024 or before.
Retail markets all around the US are doing almost the same though.
