Walmart shares have shed almost a fifth of their value since May, and CNBC's Jim Cramer is telling investors to treat that slump as an opening rather than a warning.
The stock closed at $111.54 (£84) on Tuesday, down roughly 18 per cent from the record high of $135.16 (£101) it reached on 19 May. It has fallen for four straight weeks and is roughly flat for the year. Much of that damage, though, had little to do with Walmart itself.
