Semiconductor and memory stocks dominated overnight gains following a U.S.-Iran peace deal that unlocked risk appetite and reduced geopolitical premiums. WDC (+14.7%), MU (+10.7%), MRVL (+10.5%), and ARM (+8.0%) led the charge on AI storage/memory tailwinds and analyst upgrades, while broader chip equipment plays like LRCX (+6.1%) and TER (+7.1%) benefited from softer Fed expectations. The session's biggest loser was Fox (FOX, -15.7%; FOXA, -17.3%), which announced a $22B Roku acquisition that markets instantly priced as value-destructive. Secondary winners included gig-economy and fintech names (DASH +11.8%, UBER +5.8%, COIN +6.3%), while energy underperformed (APA -6.3%) as peace hopes pressured oil.
Buy:** Semiconductor equipment and memory plays (LRCX, MU, MRVL, TER) remain structurally sound on multi-year AI capex cycles—today's moves are justified. **Avoid:** FOX and FOXA at current levels; wait for post-deal clarity before touching either. **Hold:** Fintech/crypto beneficiaries (COIN, HOOD) are sentiment-driven; take profits on 5-8% pops. Energy shorts remain tactically viable if peace deal holds.
