What drove the massive market rally on April 8, 2026?

A confirmed US-Iran ceasefire deal — with both sides claiming victory — triggered a massive risk-on reversal. The deal removed the Hormuz closure risk premium that had been embedded in markets since late March, collapsing oil volatility and sending equities surging across every sector.

Where did oil close after the ceasefire news?

WTI crude closed at $96.76 (+2.49%) and Brent at $96.51 (+1.86%). While oil recovered from intraday lows around $90-92, it remains well below the $115+ levels of last week, reflecting a partial but not complete unwind of the Hormuz risk premium.

What did Constellation Brands report tonight?

STZ delivered a catastrophic Q4 miss: EPS $1.16 vs $3.29 estimate (-64.7%), revenue $1.92B vs $2.396B estimate. Beer and wine demand remained under persistent pressure. Guidance also disappointed. The stock was down -2.32% heading into the print and further pressure is expected.

What does the VIX level mean for markets?

VIX closed at 21.04, down -18.39% on the day. This is the sharpest single-day fear collapse in weeks. A sustained move below 20 would signal full risk-on regime reset. But with Hormuz reopening uncertain and PCE data due tomorrow, Vol remains elevated relative to pre-conflict levels.

Which sectors led the rally?

Industrials +4.01%, Communication Services +2.99%, Consumer Cyclical +2.99%, Basic Materials +3.33%, Technology +2.75%. Defense underperformed the broad market on the ceasefire — RTX, LMT, NOC, GD all closed up but less than indices. Airlines surged on fuel relief.

What should investors watch tomorrow?

Core PCE price index at 8:30 AM ET is the key macro release. Estimate: prior 3.1%. A hot print would challenge the ceasefire rally. Also watch Hormuz traffic — the ceasefire doesn't automatically reopen the strait. BB and WDFC report earnings.

US-Iran Ceasefire: S&P +2.5%, Dow +1,325 Pts — Evening Close Apr 8

Post-market update — April 8, 2026 — 23:00 UTC

The Catalyst: Ceasefire Confirmed, Markets Reprice Everything

The confirmation the market had been waiting for arrived before the open: the US and Iran reached a ceasefire deal, with both sides claiming victory. The deal — fragile but confirmed — pulled the conflict premium out of oil, crushed volatility, and sent global equities on a tear.

It was the dominant macro event of the month so far. Every risk premium from the past three weeks got repriced in a single session.

S&P 500	6,782.81	+2.51%

Commodities

	Price	Change
WTI Crude	$96.76	+2.49%
Brent Crude	$96.51	+1.86%
Gold	$4,739.40	-0.79%
Silver	$73.90	-1.96%
Natural Gas	$2.735	+0.40%
Copper	$5.75	-0.52%

Oil context: WTI closed nearly $20/bbl below last week’s peak. The intraday crash was deeper — briefly touching $90 — before recovering as markets digested the ceasefire’s uncertain implementation timeline. Hormuz remains technically closed; traders are pricing ~50% probability of full reopening within 30 days.

Rates & Currencies

	Rate	Change
10-Yr Yield	4.291%	-1.20%
30-Yr Yield	4.887%	-0.69%
5-Yr Yield	3.920%	-1.41%
EUR/USD	1.1665	-0.05%
USD/JPY	158.555	+0.04%

A flight-to-safety bond bid held despite the risk-on equity move — yields actually declined. Markets are pricing the Fed on hold (98% probability per prediction markets) but not adding rate hike expectations even with the equity rip.

Defense Sector (Underperformed — As Expected)

Ticker	Close	Change
RTX	$203.48	+2.81%
BA	$217.80	+3.71%
PLTR	$140.76	-6.20%
LMT	$628.50	+0.13%
NOC	$687.47	+0.44%
GD	$350.02	+0.46%

Defense broadly underperformed the market on ceasefire news — LMT/NOC/GD barely moved. PLTR sold off -6.20% despite a rallying market, reflecting profit-taking after its recent run. BA was the exception at +3.71%, likely benefiting from airline strength (DAL beat, fuel cost relief) rather than defense tailwinds.

Crypto

	Price	Change
BTC	$71,130	-0.10%
ETH	$2,192	-0.18%
SOL	$82.75	-2.17%
XRP	$1.35	-1.28%

Crypto sat out the ceasefire rally — unusual. BTC is flat to down despite equity surge. This either reflects continued macro uncertainty or rotation back into equities. BTC prediction markets show <1% chance of $150K in April, <1% for $110K.

STZ	$1.71	~$1.16 (reported)	❌ -32.2% (adj)	Revenue also missed; guidance weak

Note: STZ GAAP EPS was $1.16 vs $3.29 GAAP estimate. Adjusted comparison suggests a miss versus the $1.71 adjusted estimate tracked on Yahoo. Headline GAAP figures reflect impairments and restructuring charges. Stock -2.32% into print — likely additional pressure tomorrow.
