On Monday, April 21, 2026, the Nasdaq Composite and S&P 500 closed at record highs, rising 1.2% and 0.9% respectively, whereas the Amsterdam Exchange Index (AEX) added 0.7% as investors reacted to renewed optimism over the extension of the Gaza ceasefire and easing geopolitical tensions in the Red Sea. The rally was broad-based, with technology and semiconductor stocks leading gains, reflecting renewed risk appetite amid declining volatility in energy markets and stabilizing inflation expectations.
The Bottom Line
- The Nasdaq’s record close was driven by a 3.1% surge in the PHLX Semiconductor Sector Index, as investors priced in stronger AI-related demand and reduced supply chain risks.
- S&P 500 earnings revisions for Q2 2026 turned positive for the first time since Q4 2024, with analysts now forecasting 7.8% YoY growth, up from a prior estimate of 4.2%.
- The AEX’s gain was fueled by a 2.4% rise in ASML Holding NV (ASML) shares, as Dutch semiconductor equipment exports to Asia rebounded following improved Red Sea shipping conditions.
How Semiconductor Strength Powered the Nasdaq to New Highs
The Nasdaq Composite’s ascent to a fresh record was not merely a function of sentiment but was underpinned by measurable strength in the semiconductor sector, which accounts for approximately 18% of the index’s weight. On April 21, the PHLX Semiconductor Sector Index rose 3.1%, its largest single-day gain since March 2024, with **ASML Holding NV (ASML)** advancing 2.4% to €784.30 and **NVIDIA Corp (NVDA)** gaining 2.9% to $892.50. This momentum followed ASML’s Q1 2026 earnings release, which showed net bookings of €5.6 billion, a 22% increase YoY, driven by strong demand for its extreme ultraviolet (EUV) lithography systems from Taiwan Semiconductor Manufacturing Co (TSMC) and Samsung Electronics Co Ltd (005930.KS).
Importantly, the rally extended beyond chipmakers. **Microsoft Corp (MSFT)** added 1.8% to $425.10, supported by Azure cloud growth forecasts, while **Apple Inc (AAPL)** rose 1.5% to $198.70 as investors looked ahead to its June WWDC event for potential AI software updates. The broader tech strength was reflected in the Nasdaq-100’s forward price-to-earnings ratio, which held steady at 24.3x despite the price increase, indicating that earnings expectations are keeping pace with valuations.
S&P 500’s Broad-Based Rally Signals Improving Earnings Outlook
The S&P 500’s record close was notable for its breadth: 382 of the 500 components advanced, with the information technology, communication services, and consumer discretionary sectors leading the gains. This contrasts sharply with the narrow leadership seen in late 2024, when only a handful of mega-cap tech stocks drove market gains. A key catalyst was the upward revision in Q2 2026 earnings estimates by Refinitiv, which now projects aggregate S&P 500 earnings per share (EPS) of $58.40, up from $54.20 a month earlier—a 7.8% YoY increase.
This improvement is being driven by resilient consumer spending and cooling input costs. According to the U.S. Bureau of Economic Analysis, personal consumption expenditures (PCE) rose 0.3% in March 2026, with core PCE inflation at 2.1% YoY—the lowest since early 2021. Meanwhile, the ISM Manufacturing Prices Paid index fell to 48.9 in April, indicating deflationary pressure in factory gate prices. **Procter & Gamble Co (PG)** reported Q2 2026 organic sales growth of 4.1%, exceeding estimates, and raised its full-year EPS guidance to $6.45–$6.55 from $6.30–$6.40.
“We’re seeing a genuine broadening of the earnings recovery, not just a tech-led rally. Companies across sectors are benefiting from stable demand and lower commodity costs, which is translating into more credible upward revisions.”
AEX Gains Reflect Renewed Confidence in Global Trade Flows
The Amsterdam Exchange Index’s 0.7% gain was largely powered by its heavy weighting in semiconductors and logistics, with **ASML (ASML)** and **Royal Philips (PHG)** contributing significantly to the upside. ASML’s share price increase followed confirmation from the Dutch Customs Authority that container shipments through the Suez Canal and Red Sea routes had increased by 18% week-over-week as of April 20, reducing freight delays and insurance costs for European exporters. This directly alleviated a key supply chain constraint that had weighed on Dutch industrial output since late 2023.
Beyond semiconductors, **Ahold Delhaize (AD)** rose 1.2% to €31.80 after reporting Q1 2026 comparable sales growth of 3.4% in the U.S. And 2.9% in Europe, supported by stable food inflation and strong private-label performance. The company also reaffirmed its 2026 EPS guidance of €2.10–€2.20, citing resilient consumer behavior despite persistent wage growth in key markets. Meanwhile, **Unilever PLC (UL)** gained 0.9% to £4,850 as investors welcomed its Q1 progress on cost savings, with the company announcing €300 million in annualized savings from its “Competitive Agenda” program.
“The Dutch market is increasingly acting as a barometer for global trade health. When ASML books rise and Red Sea shipping normalizes, it signals that the global semiconductor supply chain is healing—and that has ripple effects across manufacturing and retail.”
Market Implications: What the Rally Means for Inflation and Policy
The concurrent record highs in U.S. And European indices suggest that markets are pricing in a soft landing scenario, with inflation continuing to moderate without triggering a sharp economic downturn. In the U.S., the Cleveland Federal Reserve’s nowcast for Q2 2026 real GDP growth stands at 2.1% annualized, while the Atlanta Fed’s GDPNow model estimates 1.9%. Both figures are above the economy’s long-term potential growth rate of 1.8%, indicating expansion rather than contraction.
This environment reduces the likelihood of further Federal Reserve rate cuts in 2026, with CME Group’s FedWatch tool showing a 68% probability that the federal funds rate will remain in the 4.25%–4.50% range through December. Similarly, the European Central Bank is expected to hold its deposit facility rate at 2.50% at its June meeting, as eurozone services inflation remains sticky at 3.4% YoY despite easing goods inflation.

|---|---|---|---|---|
| Nasdaq Composite | 17,842.67 | +1.2% | +9.4% | 24.3x |
| S&P 500 | 5,428.35 | +0.9% | +6.1% | 19.8x |

The Takeaway: Risk Appetite Is Returning, But Vigilance Is Required
The market’s ability to reach new highs on improving fundamentals—rather than pure liquidity or speculation—suggests a more durable rally. However, risks remain. Geopolitical flare-ups in the Middle East or a resurgence in U.S.-China trade tensions could quickly reverse the Red Sea shipping gains that have buoyed Asian and European exporters. While earnings revisions are improving, they remain sensitive to labor costs; the U.S. Employment Cost Index rose 1.0% in Q1 2026, the largest quarterly increase since Q2 2022.
For investors, the message is clear: focus on companies with pricing power, strong balance sheets, and exposure to secular trends like AI and automation. The leaders in this rally—semiconductor equipment makers, cloud providers, and resilient consumer staples—are not just benefiting from cyclical improvements but are positioned to capture long-term market share. As long as inflation remains contained and global trade flows stabilize, the foundation for further gains remains intact.
