Daily Market Briefing — 01 July 2026

Market Recap

US markets extended their first-half rally on Tuesday, with tech stocks leading the charge. The S&P 500 gained 0.79% to close at 7,499.36, while the Nasdaq 100 jumped 1.68% to 30,276.35, fuelled by semiconductor strength. The Dow Jones added 0.26% to 52,319.20, capping its strongest first-half performance since 2021. The session's narrative was clear: AI demand continues to drive capital into tech, even as concerns mount over chip sector volatility hitting levels not seen since 2015.

Key Movers & Themes

Semiconductor Rally Defies Volatility Warnings: Chip stocks powered higher despite surging volatility threatening top gainers including AMD and Micron. KLA Corporation jumped 8.38% to 301.70, Marvell Technology climbed 7.25% to 297.90, and Lam Research gained 5.46% to 433.30. The moves came as the Trump administration lifted export controls on Anthropic's Claude Fable 5 and Mythos 5 AI models, easing concerns that had suspended the tools in June over hacking fears.

Nike Beats on Tariff Windfall: Nike topped earnings estimates despite a 12% drop in China sales, buoyed by a $986 million tariff refund that lifted profit and gross margins. The results highlight how Trump-era trade policy reversals are creating one-off boosts for US multinationals, though the underlying China weakness remains a concern for consumer discretionary stocks.

Oil Surges on Iran Supply Shock: Brent crude jumped 1.71% to $73.22 and WTI rose 0.75% to $69.75 after Iran announced it's selling oil at a 20% premium following the end of the US blockade, with 40 million barrels already exported. The ceasefire has prompted a surge in crude shipments through the Strait of Hormuz, though LNG markets face continued disruption as QatarEnergy extended its force majeure, withholding four additional cargoes until September.

The Big Question

Will the yen intervention work, or is the Fed the real problem? Japan has now spent $74 billion propping up the yen, which slid to a fresh 40-year low against the dollar on Tuesday. Analysts argue that intervention alone won't reverse losses while wide US-Japan rate differentials keep supporting the dollar — the USD/JPY pair now sits at 162.71, up 0.59% on the day. Until the Fed signals a dovish shift or the Bank of Japan hikes rates aggressively, traders are betting the yen has further to fall.

Economic Calendar — What to Watch Today

• 09:00 GMT — Eurozone Inflation Rate YoY Flash (Jun): Forecast 3.0% vs 3.2% prior. A drop would support ECB doves ahead of President Lagarde's speech at 13:00 GMT during the ECB Forum on Central Banking.
• 12:15 GMT — US ADP Employment Change (Jun): Forecast 113k vs 122k prior. A weaker print could signal labour market softening ahead of Friday's NFP, though some employers are already regretting AI-driven layoffs and rehiring workers.
• 14:00 GMT — ISM Manufacturing PMI (Jun): Forecast 54.0 vs 54.0 prior. This is the day's key release — a beat would reinforce US economic resilience, while a miss could trigger profit-taking in tech.
• 13:00 GMT — Fed Chair Warsh Speech: Markets will parse every word for clues on the Fed's rate path, especially with the yen intervention debate raging.
• 14:30 GMT — EIA Crude Oil Stocks Change: Forecast -2.9M barrels vs -6.088M prior. Watch for impact on oil prices already elevated by Iran supply dynamics.

Technical Levels to Watch

The 313.00 resistance level on KLAC is critical today — a break above would confirm the semiconductor breakout has legs. However, three chip names are now overbought on RSI (KLAC, PANW, CRWD), suggesting near-term consolidation risk. Watch for MACD bearish crossovers in mega-caps like MSFT and AAPL, which could signal broader tech weakness ahead.

Commodities & Currencies

Oil stole the show on Tuesday, with Brent's 1.71% jump driven by Iran's post-blockade supply dynamics and QatarEnergy's LNG force majeure extension. Gold slipped 0.87% to $3,988.10 as dollar strength and rising real yields weighed on the metal, while silver took a harder hit at -2.28%. Bitcoin fell 1.79% to $59,060.90, testing the theory that ETFs would make selloffs less painful — institutional adoption hasn't yet insulated crypto from volatility. Sterling gained 0.57% to 1.3242 ahead of BoE Governor Bailey's speech at 13:00 GMT.

Trading Outlook

Cautiously bullish into the ISM print, but overbought conditions in semiconductors warrant tight stops. Today's catalyst that could flip sentiment: a weaker-than-expected ISM Manufacturing PMI (forecast 54.0) would trigger profit-taking in overextended tech names, particularly those with RSI above 70. Watch the S&P 500's 7,440 level — a break below yesterday's open would signal the rally is losing steam. Stay alert at 14:00 GMT when ISM hits the wires.
