I don't hate DLTH in the way I hate scam or even fad stocks (like Fitbit). DLTH's chief problem is that it's retailing which is so depressed these days.
Decades ago I owned several retail stocks and didn't make much with them even tho I know that sector well. Only retail I own now is Walgreen's which is really quite different... more a part of medicine than conventional retailing.
Upside for DLTH is expanding into malls would be dirt cheap compared with 15 years ago, and low risk since they probably won't have to build-out stores. They can find plenty of already built stores that were recently vacated. But so many malls are dying and more will die when Sears shutters.
DLTH has another problem in common with most retailers: a business with low barriers to entry. In fact, several chains already exist in the field such as Work 'n' Gear which has been closing stores for years.
