Jacob Sonenshein warns that falling volatility is masking extreme market concentration, with gains driven by a narrow group including Nvidia (NVDA), Intel (INTC), and AMD (AMD), while hundreds of stocks lag. He highlights risks in names with earnings disconnected from GAAP results and fading hyperscaler momentum. Shifting to defense, Sonenshein points to Philip Morris (PM) as an undervalued non‑cyclical play, while flagging high‑multiple stocks like DoorDash (DASH) as potential shorts.
