Marked Performance Divergence at Month-End

The final days of August and first days of September 2026 revealed marked weakness in the NASDAQ Composite relative to the Dow Jones Industrial Average. On September 1, 2026, the NASDAQ fell 1.02% – a loss that, according to 247wallst.com, was three times the S&P 500 decline of 0.35%. The Dow Jones positioned itself in between with minus 0.84%.

Already on August 31, pressure had intensified: the NASDAQ lost 1.3%, while the Dow Jones and S&P 500 each fell 0.7%. The losses were driven by tightened financing conditions and new U.S. air strikes against Iran, as CNBC reported.

This divergence illustrates that the largest weight losses were concentrated in megacap technology stocks. The S&P 500 is more strongly influenced by large tech positions due to its market-cap weighting than the Dow Jones, whose composition is more broadly distributed across sectors.

Tech Giants Under Pressure – Defensive Stocks Benefit

Losses on September 1 were unevenly distributed across individual stocks. Alphabet (Google) lost 2.21% according to 247wallst.com, Nvidia lost 2.03%. Already on August 28, Intel and other semiconductor stocks had recorded losses, CNBC reported.

Defensive stocks were on the winning side: Merck gained 1.84% on September 1, Johnson & Johnson 1.63%, and Chevron 1.49%. Industrial stocks and the financial sector showed relative resilience against growth-oriented names.

This rotation illustrates a classic pattern: when investors reduce risk, they first abandon highly valued technology stocks and seek shelter in established companies with more stable cash flows.

Structural Differences Explain Volatility

The different performance reflects the fundamentally different construction of both indices. The NASDAQ Composite invests approximately 43% in the IT sector, while healthcare accounts for less than 9%. An index is a measure that reflects the performance of a defined basket of stocks – in the case of the NASDAQ, these are predominantly technology-heavy companies.

The Dow Jones Industrial Average, by contrast, shows a broader sector distribution with stronger weighting of industrial stocks and the financial sector. This structural difference explains why tech selloffs burden the NASDAQ disproportionately and why the Dow Jones shows better resilience during tech weakness.

For investors, this means: a NASDAQ investment is effectively a concentrated bet on the technology sector, while the Dow Jones offers more balanced sector allocation.

Monetary Policy as Valuation Risk for Tech Stocks

The main pressure on the NASDAQ came from elevated expectations regarding possible interest rate increases in September 2026. According to source reports, a shift in these expectations is the greatest direct threat to the valuation multiples at which megacap tech stocks trade. A valuation multiple describes the relationship between stock price and fundamental metrics such as earnings or revenue – a price-to-earnings ratio (P/E) of 30 means, for example, that investors are willing to pay 30 times annual earnings.

Technology stocks are traditionally valued at higher multiples because investors expect stronger future growth. When interest rates rise, these future earnings are worth less in today's money – a mathematical effect that hits growth stocks harder than established industrial stocks with more stable, nearer-term cash flows.

This monetary policy sensitivity explains why the NASDAQ reacts more volatilely to interest rate discussions than the Dow Jones.

Geopolitical Pressures and Trade Conflicts

Beyond monetary policy, geopolitical factors burden the markets. The Iran war and new U.S. air strikes against Iran in late August/early September 2026 put markets under pressure, as CNBC reported on August 31. The Dow Jones fell more than 400 points that day after news of the air strikes became known.

Trading.de also mentions tariff disputes between the U.S. and EU as a potential burden risk. These trade conflicts particularly hit technology companies with global supply chains – another reason for NASDAQ weakness.

A possible reopening of the Strait of Hormuz following the end of the Iran war could, in turn, drive growth back above 30,000 points, trading.de forecasts in its technical analysis.

Brief Recovery Phase at End of August

Not all days were negative. On August 27, 2026, the NASDAQ Composite rose 1.57% to 26,541.35 points according to CNBC, while the S&P 500 gained 0.72% and the Dow Jones advanced 0.2% (105.56 points). The driver was a rally in Nvidia based on positive revenue guidance.

The following day, August 28, however, sentiment reversed: the NASDAQ fell 0.52% to 26,402.42 points, the S&P 500 by 0.25%, while the Dow Jones closed nearly unchanged at minus 0.02%.

This volatility demonstrates the NASDAQ's dependence on individual stock news: positive Nvidia guidance could drive the index for one day, but the recovery proved short-lived.

Medium-Term Perspective and Technical Classification

A technical analysis by trading.de from July 21, 2026 (published with data as of August 25, 2026) shows the following perspective: In May/June 2026, the NASDAQ reached a new all-time high of 30,762 points. The index continues a long-term uptrend after brief downturns caused by trade disputes and the Iran war.

The 20-day average (SMA-20) stood at 29,011 points on August 25, 2026, almost at the same level as the current price. The RSI value (Relative Strength Index – a momentum indicator that measures overbought or oversold conditions) was at 56 and indicates neutrality. Values above 70 are considered overbought, below 30 oversold.

Trading.de sees the 30,000-point level as a possible sustained support. At 26,000 points, further support could establish itself, provided the trade dispute does not burden markets too heavily. Current growth is described as very erratic but fits with bullish signals on the charts.

Long-Term Forecasts Through 2030

For 2030, trading.de (as of July 2026) expects a reading well above 40,000 points. With average annual gains of 15% per year, a break above 100,000 points is projected for 2040. For 2050, precise forecasts are not possible due to too many unpredictable factors.

These long-term forecasts are based on the historical outperformance of the technology sector and the assumption that innovation and digitalization continue to advance. However, investors should view such forecasts as scenarios, not as reliable predictions.

Conclusion: Sector Weighting Determines Volatility

Performance at the August/September 2026 month-end clearly shows: the NASDAQ Composite is more susceptible to tech price declines than the Dow Jones Industrial Average. This reflects the different sector weighting of both indices. While the NASDAQ invests approximately 43% in the IT sector, the Dow Jones structure offers more diversification and thus greater resilience against tech selloffs.

The main risks for the NASDAQ remain monetary policy decisions and their impact on valuation multiples of growth stocks. Geopolitical developments and trade conflicts further amplify volatility. For investors, the choice between both indices represents a fundamental decision: concentrated tech exposure with higher volatility (NASDAQ) or broader sector diversification with more moderate fluctuations (Dow Jones).
