Wall Street’s Q1 earnings season enters its heaviest week of the cycle — with Tesla, IBM, Boeing, Lockheed Martin, RTX, United Airlines, Blackstone, GE Vernova, and Lam Research all reporting inside a five-day window. What these names say will determine whether last week’s S&P 500 and Nasdaq all-time highs were a breakout or a blow-off top.
Calendar by Day
Monday, April 20: Steel Dynamics (steel cycle read).
Tuesday, April 21: Lockheed Martin, RTX, General Motors, Philip Morris, Coca-Cola, United Airlines.
Wednesday, April 22: Tesla, IBM, Boeing, AT&T, GE Vernova, Lam Research, ServiceNow.
Thursday, April 23: Alphabet, Intel, American Airlines, T-Mobile.
Friday, April 24: Colgate-Palmolive, HCA Healthcare.
The Five Biggest Setups
- Tesla (TSLA) — most complex earnings ever; 50,000-vehicle inventory build in Q1, energy storage down 38% QoQ, street EPS US$0.37 on US$22.7bn revenue. Refinitiv Smart Estimate implies a -20.6% earnings surprise.
- Boeing (BA) — 737 MAX production discipline under regulator scrutiny; defense exposure via Iran situation a second read.
- IBM (IBM) — enterprise AI infrastructure thesis; watsonx revenue trajectory is the KPI.
- GE Vernova (GEV) — the AI-power trade. Grid-modernisation backlog and gas-turbine pricing are the signals.
- Alphabet (GOOGL) — Google Cloud growth rate, Gemini monetisation, and any early Gemini 4 signal ahead of I/O 2026.
What Wall Street Needs to See
The bull case into this week’s prints rests on three things holding:
- Margin resilience — the S&P 500 blended margin at roughly 12.8% is close to a cycle high
- Guidance — full-year 2026 guidance raises, not holds
- Capex commentary on AI — any signal that AI capex is slowing would undercut the Nasdaq’s rally
What Could Sink It
A bad cocktail of three: a Tesla miss that signals EV demand weakness, an Alphabet cloud deceleration, and any Iran-linked guidance caveats from defence names that imply extended conflict. Any two of those in the same week and last week’s all-time highs get re-examined fast.
Tail Risks for Airlines
United (Tuesday) and American (Thursday) report into a week where US jet-fuel spot prices have firmed on the Hormuz whiplash. Any airline guidance cut on fuel would ripple across transports.
Macro Overlay
Beneath the single-stock prints, the week also carries the US April PMI flash releases on Wednesday. A sub-50 manufacturing print combined with an earnings disappointment would be the sharpest test of the current bull narrative.
