Régime intrajournalier contrasté et peu lisible : détente du VIX et des rendements américains favorable au risque, mais indices américains encore sous leurs moyennes horaires principales et divergents entre eux. Le dollar recule fortement, tandis que EUR/USD et GBP/USD sont déjà surachetés à court terme. Les minutes du FOMC dans moins de deux heures augmentent fortement le risque de retournement et de volatilité.

HOLD^SPX

Hold unchanged. SPX remains above entry, the 7418 invalidation, and its 20-hour, 50-hour, 50-day and 200-day averages; positive 24-hour momentum and a low, falling VIX continue to support the long thesis. Nearby 7512-7526 resistance, elevated yields, Nasdaq underperformance, weekend gap risk and Monday's ISM release warrant caution, but closed-session stale data provide no defensible basis to update or close.

HOLD^SPX

Hold unchanged. SPX remains above entry, the 7418 invalidation, and its 20-hour, 50-hour, 50-day and 200-day averages, while positive 24-hour momentum and a low, falling VIX support the long thesis. Resistance around 7512-7526, elevated yields, Nasdaq underperformance, weekend gap risk, and Monday's ISM release warrant caution but do not justify a change on closed-session stale data.

HOLD^SPX

Hold unchanged. SPX remains above entry, the 7418 invalidation, and its 20-hour, 50-hour, 50-day and 200-day averages, with positive 24-hour momentum and confirmation from a low, falling VIX. Nearby 7512-7526 resistance, elevated yields, Nasdaq underperformance, weekend gap risk and Monday's ISM event warrant caution but do not invalidate the long thesis. Closed-session stale data provide no defensible basis for an update or close.

The long thesis remains intact: SPX is above entry, the 7418 invalidation, and its 20-hour, 50-hour, 50-day and 200-day averages, with positive 24-hour momentum and confirmation from a low, falling VIX. Hold unchanged because the market is closed and data are stale; resistance around 7512-7526, elevated yields, Nasdaq underperformance and weekend gap risk do not justify an update or close.

2026-08-19 16:00 UTCSUCCESSConfidence 62%

Journée de repricing macro violent contre le dollar, mais qui ne se transmet pas aux actions. Le dollar est vendu contre tout le bloc : EUR/USD +0,78% à 1,1667, GBP/USD +0,55% à 1,3607, USD/JPY -0,70% à 158,45. Le 10 ans américain perd 5,9 pb à 4,651 et l'or explose de +3,58% à 4548, soit +2,93% sur 24h après avoir traversé sa SMA20 horaire de 4428 en une seule bougie (12:00Z). Le VIX recule de 4,40% à 15,22, sous sa SMA50 journalière de 17,03. Tout l'appareil de mesure pointe vers un assouplissement anticipé des conditions financières. Le problème est la contrepartie manquante : les actions ne suivent pas. Le S&P 500 ne gagne que 0,12% à 7726 et reste sous sa SMA20 horaire (7741) et sa SMA50 horaire (7754) ; le Nasdaq 100 est en baisse de 0,22% à 29514, à 280 points sous ses deux moyennes horaires, malgré un rebond franc depuis son plus bas de 29292. Sur sept jours les deux indices sont négatifs (-0,47% et -0,12%). Une baisse des taux et une baisse de la volatilité qui n'achètent pas d'actions, avec l'or en tête du mouvement, ressemblent davantage à une prime de débasement ou de risque budgétaire qu'à un régime de reflation, et cette lecture n'est pas favorable aux indices. L'Europe est fermée (CAC et DAX, réouverture 20/08 07:00Z) et termine faible, le CAC clôturant à 8501,91 exactement sur son plus bas du jour, RSI horaire à 26,83. Les instruments porteurs du signal le plus net (or, baril, USD/JPY, VIX, 10 ans) sont tous non négociables en simulation ; le champ éligible se réduit au S&P 500, au Nasdaq 100, à l'EUR/USD et au GBP/USD. Régime : extension généralisée, direction non confirmée par les actifs risqués, à moins de deux heures d'un événement à fort impact.

HOLD^CAC

Thesis intact: VIX at 17.61 is well below the 20 risk-off trigger and trending down (-1.12% 1h, -5.06% 24h), signaling continued risk-on appetite. Price 8428.17 is now further above the 8250 stop (5.39x 1h ATR) and above 1h SMA20/50 (8339.97/8360.50) and daily SMA50/200 (8300.95/8176.77). RSI 1h at 64.69 shows bullish momentum without extreme overbought exhaustion. Position has moved to +0.44R with bounded risk at 0.31% of capital. No invalidation trigger hit; maintaining stop 8250 / target 8550.

HOLD^CAC

Thesis intact: VIX 18.58 remains below the 20 risk-off trigger, price 8372.28 stays well above the 8250 stop and above 1h SMA20/50 (8342.6/8356.7) as well as daily SMA50/200, RSI 55.69 (1h) shows no exhaustion. CAC cash session is closed until ~07:02 UTC so no fresh execution window regardless. PnL near flat (-4.19), risk bounded at 0.31% of capital. No invalidation trigger hit; keeping stop 8250 / target 8550 unchanged.

HOLD^CAC

Thesis intact: VIX 18.58 stays below the 20 risk-off trigger, price 8372.28 sits well above the 8250 stop and above 1h SMA20/SMA50, RSI 55.69 shows no exhaustion. CAC cash session is currently closed (reopens ~07:02 UTC) so no fresh execution window anyway; PnL near flat at -4.19 with risk bounded at 0.31% of capital. No invalidation trigger hit, keeping stop 8250 / target 8550 unchanged.

HOLD^CAC

Thesis unchanged: VIX at 18.58 remains below the 20 risk-off threshold, price (8372.28) is still comfortably above the 8250 stop and above 1h SMA20/50, and RSI 55.69 shows no overbought exhaustion. Position PnL is flat (-4.19) with risk still bounded at 0.31% of capital. No invalidation trigger reached; maintaining stop 8250 / target 8550.

HOLD^CAC

Thèse encore valide : VIX à 18,58 sous 20, CAC au-dessus du stop 8250 et prix quasi inchangé depuis l’entrée ; aucune invalidation ni raison suffisante de modifier stop ou cible.
