What were the biggest market events the week of March 20, 2026?

Four events defined the week: (1) The Fed held rates Wednesday but introduced a stagflation framing — growth forecasts cut, inflation raised simultaneously; (2) US military began actively striking Iranian assets in the Strait of Hormuz by Friday, with Trump calling NATO allies 'cowards' for refusing to join; (3) SMCI imploded -33.21% on 221M shares (7.6x average volume); (4) the nuclear/AI power trade unwound hard with VST -12.64% and CEG -10.9%. Defense was the only sector green all five days.

What did the Fed decide on March 18 and why did markets sell off?

The Fed held rates as expected (96% probability priced in). The selloff came from the statement's tone: GDP growth forecasts were cut and inflation forecasts were raised simultaneously. That's the stagflation box — the economy slows but the Fed can't cut because inflation stays elevated. It removes the put. The 10Y yield settled at 4.391%. Next decision is April with another 96% hold probability — the Fed is in wait mode while conditions deteriorate around it.

Why did SMCI fall -33% on March 20?

SMCI (Super Micro Computer) dropped -33.21% on 221 million shares — 7.6x its 29M daily average. The 2x short ETF SMCZ gained +66.56%, confirming pre-positioned institutional shorting into a known catalyst. The volume signature (gap down, no recovery, extreme turnover) points to forced liquidation on a material negative event. Collateral damage: NVDA -3.25%, INTC -5.00%, MU -4.81%.

What happened in the Strait of Hormuz this week?

The week escalated from diplomatic signals to kinetic operations. By Friday, US military was actively striking Iranian assets in and around the Strait of Hormuz — the waterway through which roughly 20% of global oil supply passes. Trump publicly labeled NATO allies 'cowards' for refusing to participate, opening a coalition rift that reduces de-escalation options. Brent hit $106.51, tanker ETF BWET gained +17.83%, and 242 military flights were airborne at the Friday close.

Which earnings prints mattered most this week?

FedEx was the standout — $5.25 EPS vs $4.17 estimate, a 26% beat with raised guidance, +10.34% overnight. Accenture was the cleanest: FCF +36.7% YoY, GenAI bookings accelerating. Micron was mixed: Q2 EPS beat but Q3 revenue guide missed consensus — market sold the guide. Alibaba reported a revenue beat but net income -66.7% YoY on cloud/AI reinvestment, stock -7.1%. Elbit Systems (ESLT) reported strong in a geopolitically hot week for Israeli defense.

What should investors watch the week of March 23?

PDD Holdings ($138B cap) reports Monday BMO — the most important print of the week, a direct read on Chinese consumer health against war-driven commodity pressure. Karman Holdings (KRMN, defense/aerospace) reports Monday AMC — a live proxy for defense spending sentiment with Hormuz elevated. U Mich Consumer Sentiment follows March 27 (prior 55.5, already at recessionary levels). And Hormuz over the weekend is the variable that overrides everything else — any escalation or NATO response resets Monday's open.

Week of Mar 20: Hormuz Strike, Fed Stagflation Warning, SMCI -33%

Week of March 16–20, 2026 | Friday close

A Fed week that became a war week. The Fed held rates Wednesday but removed the comfort with a stagflation framing. By Friday, US forces were striking Iranian assets in the Strait of Hormuz, SMCI had imploded -33%, and the nuclear/AI power trade was in freefall. Defense held green every day. S&P closed -1.51%.

Fed — Wednesday March 18

Rates held. But the statement was the event.

The Fed cut its GDP growth forecast and raised its inflation forecast in the same breath — the stagflation signal the market had been dreading. Growth slows, but inflation stays elevated, so the Fed can’t cut to stimulate. The put is removed.

10Y yield settled at 4.391%. Next decision April — 96% hold probability again. The Fed is watching, not moving.

Earnings

ESLT — Elbit Systems ✅ (Monday March 17)

Israeli defense prime. Strong print in a geopolitically active week for Israeli defense contractors. Set the tone for the defense trade that held all week.

→ Full recap

MU — Micron ⚠️ (Wednesday March 18, after close)

The split read. IBD ran “obliterated estimates” on the Q2 EPS beat. The market sold it anyway — the Q3 revenue guidance came in below consensus. Two correct headlines, two different metrics. In a risk-off tape, the guide always wins.

Friday close: -4.81%

→ Full recap: MU Q2 beat vs Q3 guide miss explained

FDX — FedEx ✅✅ (Thursday March 19, after close)

The week’s standout print.

$5.25 EPS vs $4.17 estimate — 26% beat. Guidance raised. +10.34% overnight.

In a week where most names bled, FedEx’s print was a standalone positive signal of resilient logistics demand.

→ Full recap

BABA — Alibaba ❌ (Thursday March 19)

Revenue beat. Net income -66.7% YoY on intentional cloud/AI reinvestment. Market read the income line, not the revenue line. Stock -7.1%. The strategic context matters — this is a choice, not a miss — but you can’t beat the tape in a risk-off week.

→ Full recap

ACN — Accenture ✅ (Thursday March 19)

The cleanest beat. FCF +36.7% YoY. GenAI bookings accelerating and converting to revenue in 12-24 months. +4.3%. The enterprise AI implementation layer is working.

→ Full recap

XPEV — XPeng (Friday March 20, before open)

First-ever quarterly profit. Weak forward revenue guidance offset the milestone. Mixed reaction.

ZGN — Zegna (Friday March 20, before open)

Full-year profit €109M, +20% YoY. Luxury holding up against macro headwinds — quiet signal.

The Week’s Dominant Themes

Hormuz — Diplomatic Signal to Active Strike

Monday: Netanyahu ground phase signal (LVL 9/10, 7 corroborating sources). Friday: US actively striking Iranian assets in the Strait. Trump calls NATO “cowards.”

Brent: $106.51 | WTI: $97.82
BWET (tanker ETF): +17.83%
242 military flights airborne at close
1,044 GDELT global incidents

→ Morning rotation brief (Thursday) · Thursday evening close

SMCI -33% — Single-Name Implosion

221M shares. 7.6x average volume. SMCZ +66.56%. No recovery. Collateral damage: NVDA -3.25%, INTC -5%, MU -4.81%. The AI infrastructure stack took secondary hits.

Nuclear/AI Power Unwind

VST: -12.64% | CEG: -10.90%

The “buy utilities for AI datacenters” trade broke this week. Elevated yields + risk-off liquidation + geopolitical uncertainty around energy infrastructure. The thesis isn’t dead but the certainty premium is gone.

StockScout v2 — Week in Review

Portfolio held defensively all week — high RS (safety) stocks, energy and defense tilt, low beta. Friday positions: XOM, REGN, GILD, CVX, GD. Against a -1.51% S&P close the construction held. GD +1.09%, energy names benefited from the oil spike, healthcare provided defensive ballast.

The Macro Risk-Off filter (10Y yield 4.391%, elevated and rising) correctly downgraded lower-safety BUYs to HOLD throughout the week, concentrating exposure in the high-RS tier.
