TK Stocks With Massive Buffett-like “Moats” (SHOP, LUX, ELLI, CALM)

I’m doing a story on a few smaller stocks that most people wouldn’t know about that also happen to have big “moats” or competitive advantages that will help their businesses stay successful for years to come. I know four stocks I will be featuring so far — SHOP, LUX, ELLI and CALM. I’m seeking comments on the following — any of the above stocks and their respective “moats”, competitive advantage and moats in general, and additional under-the-radar stocks with moats.
