Market brief — September 4, 2026

Yesterday, markets extended a rates-led relief rally: the CAC 40 finished at 8,286.4 (+0.07%), the DAX at 26,003.32 (+0.63%) and the Euro Stoxx 50 at 6,382.59 (+0.32%), while the S&P 500 closed at 7,747.71 (+1.06%) and the Nasdaq at 26,584.06 (+1.40%). The dominant macro driver shifted from a pure higher-for-longer panic to a short-end repricing lower after Fed Governor Christopher Waller signaled patience on rates if disinflation continues, which Reuters said pushed two-year Treasury yields down to 4.3381% from a 20-month peak and helped equities stage a broad risk-on move^[1][3][5]. That is still a genuine macro repricing, not just a mechanical squeeze, because the move was confirmed by a bull-steepening curve, softer dollar tone and stronger duration-sensitive growth assets^[1][4][7].

The key cross-asset message is that the market is now testing whether the recent bond selloff had gone too far. The front end is the main transmission channel: traders trimmed September hike odds after Waller’s comments, and that immediately supported U.S. tech, European equities and rate-sensitive parts of the curve^[3][5]. Yet oil remains a major offset, with Brent near $95.5–$95.7 a barrel and set for its steepest weekly gain since mid-July on intensifying U.S.-Iran tensions, keeping inflation risk alive and limiting how far yields can fall without a growth scare^[1][10]. The near-term implication is a fragile coexistence of lower rate pressure and elevated commodity risk: growth equities can keep extending, but only if oil stops worsening the inflation impulse and the long end stays orderly^[1][8][10].

The Cash Scanner confirms that today’s leadership is still overwhelmingly U.S. growth and quality momentum, but with a subtle rotation under the surface. Snowflake (SNOW) scored 35 and jumped 16.6% on a 20-day breakout with volume expansion, while C3 AI (AI) scored 38 with a 3.6% gap and BB squeeze expansion, and Zeta Global Holdings (ZETA) scored 34 with a 7.4% gap and strong breakout/ADX signals; that is classic software beta responding to falling discount-rate pressure. At the same time, Genworth Financial (GNW) scored 46 on a 2.5% gap and breakout signals, and Johnson & Johnson (JNJ) and Gilead Sciences (GILD) both show strength in defensives/health care, suggesting the tape is not a one-factor momentum chase but a mix of rate-sensitive growth plus selective quality shelter[Scanner]. The concentration remains U.S.-centric and tech-heavy, with three software names in the top 10, but the presence of insurance, biotech and health care argues for a broader risk appetite rather than a narrow squeeze[Scanner].

Over the next 1–5 sessions, the dominant narrative is whether Waller’s dovish tilt marks the start of a sustained reversal in hike expectations or merely a pause in a still-volatile inflation regime. Consensus now leans toward “no immediate panic hike,” but the market is already pricing some of that relief, so the asymmetric surprise is a hotter payrolls/inflation combo that re-prices the front end back up and reverses the soft-duration trade^[1][5][7]. A credible contrarian scenario is that the bond market keeps bull-steepening if labor data cools, in which case cyclicals and energy lag while software leadership broadens further.

The most important catalysts are U.S. nonfarm payrolls and the unemployment rate later today, which can either validate the disinflation narrative or restore front-end tightening risk^[1][7]; any follow-through in Fed communication, especially from more hawkish members, which could quickly undo the easing in rate-hike odds^[5]; and the next move in crude and Middle East headlines, because another leg higher in Brent would re-tighten inflation expectations and cap equity multiples^[10]. In Europe, bond yields and the ECB reaction function remain the secondary macro anchor, but they will mainly matter through spillover from U.S. rates and energy.

The main risks are a payrolls upside surprise that revives September hike probabilities, a renewed oil spike that re-anchors inflation fear, and any disorderly move back toward the recent highs in Treasury yields that would pressure the Nasdaq leadership and narrow the advance^[1][10]. If the two-year yield holds below the recent 4.41% peak and Brent stabilizes, the risk-on extension should remain intact; if either breaks higher, the current tech-led rally becomes vulnerable. Watch the S&P 500 above 7,700, the Nasdaq’s follow-through after the 1.40% move, and whether SNOW, AI and ZETA keep breaking out while GNW and JNJ signal rotation into defensives rather than outright de-risking. If the front end keeps easing and oil stops climbing, the tape can broaden; if not, the rally remains a rates-driven squeeze with limited endurance.

Bonne journée aux p&l makers.
