In my opinion......if your thesis on DOL is that its not a buy because it will soon saturate the market with Dollar stores, I think you may be overthinking this one. these guys know how to guide. they have beaten or matched estimates 11 out of the last 12 quarters and analysts expect them to grow earnings more than 61% between 2016 and 2019. Thats pretty impressive and thats not even including the potential of a takeout or the possible expansion into the US.
Maybe priced to perfection today, but as the earnings grow in this highly predictable business, the shareprice will also follow. Even if you get a multiple contraction, by 2019 when they're pulling in $4.85 a share in earnings, the shareprice will be much higher than it is today.
I'm a buyer on dips.
