Jefferies Comments on CVS, Walgreens' Share Gain in TV Markets

“This month we have decided to take a look at drugstore market share changes over the last few years across the top TV markets in the U.S.,” Jefferies wrote in a report. “As the industry consolidates, larger players such as CVS Caremark

and Walgreens

continue to gain share. Indeed, in 13 of the top 15 TV markets the two companies combined have approximately 50% or more market share, up from seven of 15 markets in 2005.” CVS closed Thursday at $37.58; Walgreens closed at $42.46.
