Market brief — June 28, 2026

Vendredi, US markets closed in slight decline, with the S&P 500 ending at 7,357.49 (-0.01%) and the Nasdaq at 25,358.60 (-0.46%), while European indices showed resilience: the CAC 40 gained 0.55% to 8,431.61, the DAX rose 1.03% to 24,994.83, and the Euro Stoxx 50 advanced 0.85% to 6,267.53^[1]. Overnight, Asia experienced a violent tech-led selloff, with the Nikkei falling 4.15% and Korea’s KOSPI collapsing 5.81%, signaling a sharp risk-off rotation ahead of US inflation data^[1]. This divergence reflects a systematic unwind of large-cap semiconductor valuations, driven by repricing of the Fed’s rate path amid sticky PCE inflation (4.15%) and growing caution over the delayed OpenAI IPO^[1][4].

The macro regime remains dominated by inflation expectations and central bank signaling, with positioning shifting from crowded tech longs toward cyclicals and biotech. Cross-asset flows confirm de-risking: yields are firm, the dollar is stable, and credit spreads are widening slightly, while oil remains range-bound. The overnight Asian selloff suggests CTA/vol-driven pressure, but US biotech and healthcare names show discretionary strength, indicating early rotation rather than full capitulation. Notably, the divergence between equities and yields implies investors are hedging rate risk while seeking idiosyncratic momentum in non-tech sectors.

Today’s Cash Scanner TOP 10 highlights concentrated momentum in US biotechnology and healthcare: Teladoc Inc (TDOC) scores 48 with a +6.1% gap and a 20-day breakout; Guardant Health Inc (GH) scores 44 with a +4.4% gap and MACD bullish; and Beam Therapeutics Inc (BEAM) scores 45 with a +2.6% gap and rising vortex[scanner]. The sector mix is 4× biotechnology, 2× healthcare, plus airlines, beverages, and financial services, signaling early regime shift toward idiosyncratic, non-tech momentum. These signals align with broader flows favoring defensive growth amid tech volatility.

Key agenda items for the week include: (1) US PCE inflation data on Tuesday, likely to drive rate expectations and volatility; (2) Fed Chair Powell’s speech on Wednesday, which could clarify the rate path; and (3) European cyclical earnings on Thursday, with potential sector rotation if results beat. All three events are high-impact for indices and rates.

Risks to watch: (1) A surprise upside in PCE inflation could trigger a sharp rate repricing and equity selloff; (2) Geopolitical escalation in Asia may amplify risk-off flows; (3) Liquidity event in crypto or tech could spill into equities, especially if Bitcoin breaks support.

Actionable lines: (1) If S&P 500 holds 7,300 support and biotech volume surges, consider long TDOC (TDOC) with a stop below 7.80; (2) If PCE exceeds 4.2%, fade Nasdaq longs and short MRVL (Marvell) on breakout failure; (3) Monitor GH (Guardant Health) for a confirmed 20-day breakout above 152 as a high-probability entry.

Bonne journée aux p&l makers.
