Day narrative: Stocks snapped back from Wednesday's hawkish-Fed selloff, with chips doing the heavy lifting on US-Iran peace-deal optimism ahead of the formal June 19 signing in Switzerland. It was a tale of two tapes — the Nasdaq roared while the Dow barely budged, dragged by an IT-services scare.
Sectors: Best Semiconductors (chip names up 4–7%) · Worst IT Services (Accenture's guidance cut bled across the group)
Movers:

• SMCI +10.37% — rode the broad semiconductor/AI-infrastructure rally
• TSM +6.94% — chip strength and easing geopolitical risk lifted the foundry leader
• AVGO +4.70% — AI accelerator and networking demand tailwinds
• IBM -5.05% — Accenture narrowed full-year revenue guidance, reviving enterprise IT-spending fears across services names

• US-Iran interim peace deal extends the ceasefire 60 days; formal signing set for June 19 in Switzerland, easing oil and risk premiums
• IPO watch: Anthropic filed its S-1 (June 1) at a ~$350B valuation; OpenAI eyeing a Q4 listing window — neither is publicly traded yet
Tomorrow: Watch the formal US-Iran signing in Switzerland for follow-through on the risk-on tape. Quad-witching options expiration Friday could amp up volume and volatility. Micron's June 24 earnings loom as the next big AI-memory catalyst.
