TL;DR

The S&P 500 and Nasdaq notched record closes this week, powered by Q1 2026 earnings that are running 28.2% above year-ago levels -- the strongest quarterly growth since late 2021. Three of the "Magnificent 7" (Alphabet, Amazon, and Meta) delivered the biggest upside surprises. Advanced Micro Devices jumped 19% on robust AI chip demand. Despite oil near $100 and a fragile Iran ceasefire, corporate America is outperforming every benchmark. Nvidia, Walmart, and Home Depot have not yet reported. The risk map remains constructive for stocks, but key triggers are lined up for the week ahead.

What Happened: S&P 500 Earnings Record High in 2026

On Wednesday, May 6, the S&P 500 gained 1.46%, the Nasdaq added 2.03%, and the Dow rose 1.24%, all closing at record highs. The benchmark S&P 500 is now up approximately 8% in 2026 and has surged more than 14% since its March 30 low, when markets swung sharply on the onset of the US-Iran conflict. The Nasdaq is up 13% year-to-date.

The primary engine is earnings. With 89% of S&P 500 companies having reported Q1 2026 results, the blended earnings growth rate stands at 28.2% year-over-year -- the highest since Q4 2021, according to LSEG Data and Analytics. By Saturday, May 9, that figure was still rising as remaining reports came in stronger than expected.

The magnitude of upside surprises is equally striking. According to FactSet, 84% of S&P 500 companies beat consensus EPS estimates in Q1 2026, above the five-year average of 78% and the ten-year average of 76%. In aggregate, companies are reporting earnings 18.2% above estimates -- nearly three times the five-year average of 7.3%. Deutsche Bank chief US equity strategist Binky Chadha described the result as "arguably the strongest earnings growth in two decades" when adjusted for base effects.

The three biggest contributors to the upside versus forecasts were Alphabet, Amazon, and Meta -- three of the so-called Magnificent 7 large-cap technology and AI infrastructure companies. Advanced Micro Devices (AMD) soared nearly 19% on Wednesday after forecasting quarterly revenue above expectations on strong demand for its data center AI chips. Intel shares rose 4.5% on the same day, while the Philadelphia Semiconductor Index (SOX) rallied 4.5%, lifting its 2026 gain to 62%. Intel also received a separate catalyst this week: as covered on the ChartDojo blog, Intel landed a preliminary chip manufacturing deal with Apple, sending INTC up 14% on Friday and further validating the US chipmaker's AI-era revival.

Analysts at LSEG now project full-year 2026 S&P 500 earnings growth of 22.6%, with forward estimates revised higher across each of the next three quarters since April 1. The jobs market has provided additional support: the US economy beat payroll expectations for the second consecutive month in May, reducing near-term recession risk.

Why Markets Moved: AI, Resilience, and Ceasefire Relief

Three forces explain the rally's durability. First, AI investment continues to translate into tangible margin expansion for major technology and cloud companies. Massive capital spending on data centers and inference infrastructure is generating returns faster than analysts modeled.

Second, corporate America has shown resilience against the Iran war-related oil shock. Supply chains adjusted, cost pass-through was managed, and consumer demand held firmer than feared. "Because things have not gotten worse and the ceasefire has been in place for some time now, it's been earnings that have driven the move higher," said Chris Fasciano, chief market strategist at Commonwealth Financial Network.

Third, a tentative US-Iran ceasefire that has been in place since late April gave equity investors several weeks of relative calm to focus on company results rather than oil-driven macro risk. The relief in Brent crude -- which fell about 8% to near $101 a barrel last week on hopes of a peace deal -- also eased inflationary pressure concerns that had been weighing on rate expectations.

Implications for Traders

Equity traders: The rally is fundamentally driven, not just momentum. Upward earnings revisions reduce the risk that current valuations will compress sharply absent a macro shock. However, the S&P 500's forward price-to-earnings (PE) ratio -- which measures how much investors pay for each dollar of expected future earnings -- has stretched higher as prices rose faster than estimates at times. Selectivity within the index matters: breadth has widened, but tech and AI names remain the primary drivers.

Futures traders: S&P and Nasdaq futures remain in an uptrend, with records providing support on pullbacks. Energy and oil service names face a more complex setup: higher energy prices boosted earnings for energy sector companies, but any Iran peace deal breakthrough would reprice that tailwind quickly.

Crypto traders: The risk-on sentiment in equities has been broadly supportive for digital assets. Bitcoin has held near the $80,000 level as institutional demand accelerates through ETF inflows. A continuation of the earnings-driven equity rally would typically maintain the positive backdrop for risk assets including crypto.

Potential Positives vs Negatives

Positives:

  • Q1 earnings running at 28.2% growth, the strongest since Q4 2021, with forward estimates still rising.
  • AI investment cycle continues to drive productivity gains across Magnificent 7 and semiconductor companies.
  • Jobs market firm: second consecutive beat reduces recession risk and keeps consumer spending supported.
  • Full-year 2026 EPS growth now projected at 22.6% by LSEG, with quarterly estimates revised higher through Q4.
  • Ceasefire holding long enough for market focus to shift from macro risk to company fundamentals.

Negatives:

  • Brent crude remains near $101 -- elevated oil keeps inflation pressure real and delays Federal Reserve rate cut expectations.
  • Iran ceasefire is now under renewed strain as of May 9, with US-Iranian naval clashes in the Strait of Hormuz and Iran warning that the US has "crossed the point of no return" on ceasefire terms. Any breakdown would send oil higher and stress risk assets quickly.
  • Nvidia has not yet reported. As the largest company by market capitalization in the index, a miss or cautious guide would have an outsized negative impact.
  • Forward PE ratios are stretched: if earnings growth decelerates from 28% toward the historical average of 8-10%, multiples would need to compress.
  • The PHLX semiconductor index is up 62% YTD -- crowded positions in AI stocks increase the potential magnitude of any reversal.

What Could Happen From Here: Base, Upside, and Downside Scenarios

Base scenario (most likely): Nvidia reports strong results in the coming weeks, further validating the AI capex cycle. The S&P 500 holds near record levels with modest volatility tied to Hormuz headlines. Oil stays in the $95-$110 range, keeping inflation risks elevated but manageable. The Fed holds rates steady, with the first cut now expected no earlier than December 2026. Stocks grind higher, supported by earnings revisions. This scenario is confirmed by Nvidia guidance in line with AMD's tone and continued ceasefire. It is invalidated by a Nvidia miss or a sharp oil spike above $120.

Upside scenario: A US-Iran peace deal announcement -- which both sides were reportedly close to this week -- would push Brent crude sharply lower, potentially below $85. That would revive Fed rate cut expectations, compress energy-inflation risk, and extend the equity rally meaningfully. Combined with a strong Nvidia report, S&P 500 could push 5-7% above current record levels within 30 days. Confirmed by formal Iran peace announcement and Brent closing below $90. Invalidated by Iran rejecting terms or new Hormuz escalation.

Downside scenario: Hormuz clashes escalate into a broader military exchange, Brent spikes back toward $115-$120, and inflation concerns force the Fed to signal rates higher for longer. In this case, stretched tech multiples compress, and the S&P 500 gives back 8-12% from current record levels. A Nvidia revenue miss on the same backdrop would amplify the selloff. Confirmed by Brent above $115 with supply-route disruption headlines and rising 10-year Treasury yields above 5%. Invalidated by ceasefire restoration within 48 hours.

What to Watch Next (24-72 Hours)

  • Iran response to US peace proposal: A formal reply is expected this weekend. Acceptance or rejection will move oil 3-6% in either direction and reprice futures open on Monday.
  • Brent crude above or below $100: The $100 level has become a psychological and inflation threshold. Watch Monday's open for direction.
  • Nvidia earnings (upcoming): The single most important remaining catalyst for the equity rally. AMD's strong forecast raises the bar.
  • Treasury yields: The 10-year yield remains a key inflation proxy. If yields rise materially above current levels, tech valuations face pressure.
  • Walmart and Home Depot reports: These consumer bellwethers will signal whether the earnings strength extends beyond tech into discretionary spending.

FAQ

Why is S&P 500 earnings growth so high in Q1 2026?
The combination of AI-driven productivity gains, resilient consumer spending, and favorable year-ago comparisons (when Iran war fears briefly weighed on earnings guidance) produced a larger-than-expected upside. Deutsche Bank estimates that stripping out special factors, underlying growth may be the strongest in roughly two decades.

Does the Hormuz tension pose a real risk to the stock market rally?
Yes. The ceasefire that allowed equity markets to focus on earnings is now under active strain. A breakdown in ceasefire terms or a Brent crude spike above $115 would reprice inflation risk, push Fed rate cut expectations further out, and compress the tech sector's stretched forward valuations.
