Walgreens Co. is considered the leading drug store company in the sector. When a leading stock declines traders can look for other stocks in the industry group that could be under pressure to trade. This is called a sympathy play. CVS Caremark Corp.(NYSE:CVS) is declining lower by 0.34 cents today to $33.39 a share. This stock will have very important intra-day support around the $33.00 level. This is a likely bounce area for the stock should it trade down to that level.
