Should you own both COST and ULTA?
+

What are the risks of COST vs ULTA?
+
COST: Costco's premium valuation embeds high expectations for continued same-store sales growth and margin expansion. Any consumer slowdown or competitive pressure from BJ's, Sam's Club, or Amazon would compress the multiple. ULTA: Sephora's expansion through Kohl's partnership has narrowed Ulta's geographic advantage. Same-store sales growth has decelerated; the question is whether this is temporary or structural. Mass beauty brand consolidation (e.g., e.l.f. taking share) creates pricing pressure.
