Share on:

Key Takeaways:

*Wall Street closed H1 2026 at record highs, led by AI and semiconductor stocks despite valuation concerns.

*Easing US-Iran tensions and lower oil prices improved risk sentiment by reducing inflation and supply disruption fears.

Market Summary:

Wall Street extended its record-setting rally on Tuesday, closing the second quarter and first half of 2026 on a strong note as investors continued to embrace artificial intelligence (AI)-driven growth despite lingering concerns over valuations and interest rates. The Nasdaq Composite surged 1.52%, while the S&P 500 gained 0.79% to record its strongest quarterly performance since 2020. The Dow Jones Industrial Average advanced 0.26%, marking a second consecutive record close and its best quarterly gain since 2022. Technology and semiconductor stocks once again led the market higher, with the Philadelphia Semiconductor Index (SOX) posting its best quarter on record, highlighting continued confidence in AI infrastructure spending and the long-term earnings potential of chipmakers. Although semiconductor shares experienced bouts of volatility in recent weeks amid valuation concerns, investors returned to the sector as optimism surrounding AI demand remained intact.

Market sentiment also received support from easing geopolitical tensions in the Middle East. Progress in negotiations between the United States and Iran, alongside improving shipping conditions through the Strait of Hormuz, helped reduce fears of prolonged energy supply disruptions and pushed oil prices sharply lower from their conflict-driven highs. Lower crude prices have eased inflation concerns, improving expectations for consumer spending and corporate profitability while reducing one of the key macroeconomic risks that had weighed on equities earlier in the quarter. This combination of moderating energy prices and resilient economic activity has reinforced the market’s soft-landing narrative and encouraged investors to maintain exposure to risk assets.

Meanwhile, stronger-than-expected US economic data continued to underpin confidence in the economy but also reinforced expectations that the Federal Reserve may need to keep monetary policy restrictive for longer. The latest JOLTS job openings report highlighted continued strength in labour demand, while stable consumer confidence suggested that economic activity remains resilient despite elevated interest rates. Markets have increasingly priced in the possibility of at least one additional Federal Reserve rate hike before the end of 2026, particularly after recent comments from Fed Chair Kevin Warsh signalled a willingness to prioritise inflation control if price pressures remain persistent. Rising Treasury yields and a stronger US dollar have therefore emerged as the primary macro risks facing equities in the second half of the year, especially for high-growth technology companies whose valuations remain highly sensitive to interest-rate expectations.

Looking ahead, Wall Street’s attention is rapidly shifting toward the upcoming earnings season, which is widely viewed as the next major catalyst for the market. After an exceptionally strong first half driven largely by AI optimism, investors are now looking for corporate earnings and forward guidance to justify elevated valuations and record levels of capital expenditure on AI infrastructure by major technology companies. While analysts generally remain constructive on the outlook, there is growing recognition that future gains will require stronger fundamental earnings support rather than multiple expansion alone. At the same time, several strategists have noted that the recent rally has begun to broaden beyond mega-cap technology, with increased participation from financials, industrials, healthcare and small-cap stocks, suggesting improving market breadth and a healthier overall bull market. However, many also caution that after one of the strongest quarters in years, profit-taking, sector rotation, or any disappointment from earnings, Federal Reserve policy, or geopolitical developments could trigger periods of heightened volatility even as the longer-term outlook remains broadly positive.

Technical Analysis

Nasdaq, H4: 

The Nasdaq remains firmly within a medium-term bullish trend after rebounding strongly from the June correction, with price once again approaching the key resistance level at 30,580. The index continues to post higher highs and higher lows, indicating that buyers remain in control despite the recent period of consolidation below record highs.

Following the recovery from the 28,535 support, the Nasdaq has steadily regained bullish momentum and is now testing the upper boundary of its recent trading range. A decisive breakout above 30,580 would confirm the continuation of the prevailing uptrend and could open the door for a fresh leg higher. On the downside, 28,535 serves as the first key support, followed by 26,905, where stronger buying interest is expected to emerge should profit-taking accelerate.

Momentum indicators continue to improve, supporting the constructive outlook. The Relative Strength Index (RSI) has climbed back above the neutral 50 level to around 58, suggesting that bullish momentum is strengthening without yet reaching overbought conditions. Meanwhile, the Moving Average Convergence Divergence (MACD) has completed a bullish crossover above the signal line, while the histogram has turned positive, indicating that upside momentum is rebuilding after the recent consolidation phase.

Resistance Levels: 30,580.00, 31,490.00

Support Levels: 28,535.00, 26,905.00
