Coupang is a phenomenal buy because a board member just bought $136 million of stock, probably the largest non-founder insider purchase ever seen, and there is only one reason to do that. It trades at about 20x next-12-month EBITDA, with EBITDA expected to grow about 30% a year for the next few years, though margins compress slightly this year on Taiwan expansion. Versus Sea, Coupang looks a little cheaper after being overly punished for its data breach. x.com x.com x.comÂ
