Dow Jones gains 2.46% in October 2026 as Nasdaq 100 falls 1.86%

A marked shift is taking place at US stock exchanges in October 2026: While the Dow Jones Industrial Average is posting gains, technology stocks are coming under heavy selling pressure. On 16 October, the Dow rose 243 points or 0.5 per cent, while the Nasdaq Composite fell 0.5 per cent at the same time. This divergence persists throughout the month and marks a change in investor sentiment, as growth-oriented positions are being reduced and capital is being rotated into defensive sectors.

Dow gains in October, Nasdaq loses

Through 15 October 2026, the Dow Jones has risen 2.46 per cent in the current month, while the Nasdaq 100 has fallen 1.86 per cent in the same period. The performance difference between the two indices is thus 4.32 percentage points in the Dow's favour. For the week through 15 October, the Dow recorded a gain of over one per cent, while the S&P 500 fell 0.60 per cent and the Nasdaq Composite fell 1.84 per cent. The Russell 2000, the index for smaller US companies, lost 2.31 per cent over the same period.

On 16 October around midday, the S&P 500 was trading at 7,718 points, down 0.34 per cent, the Nasdaq Composite stood at 26,419 points (down 1.09 per cent), and the Dow Jones at 52,327 points (up 0.29 per cent). Price data from Bavest show for 16 October at 2 a.m. CEST an S&P 500 at 7,659.44 points (down 1.09 per cent since the previous close), a Nasdaq Composite at 26,140.03 points (down 2.15 per cent since the previous close).

Technology sector under pressure

The technology sector recorded significant losses within a trading week. Over five trading days, the sector fell 5.67 per cent, with an additional 2.92 per cent loss on Friday alone. This made technology the most burdened sector of the week. The selling pressure was particularly evident in semiconductor stocks: the VanEck Semiconductor ETF lost one per cent on 16 October and accumulated a weekly loss of eight per cent. Among the losers were Micron Technology, Advanced Micro Devices and Sandisk. Market observers attributed this to persistent concerns about competitive pressure from China.

The broader technology sell-off also affected other growth-oriented areas: the industrial sector declined 2.64 per cent, communication services fell 0.74 per cent.

Defensive sectors benefit from rotation

Capital flowing out of technology stocks migrated to traditional financial and defensive stocks. Within Dow components, JPMorgan rose around two per cent and Goldman Sachs rose about one per cent. Nike and Merck also gained around one per cent each. Salesforce and Home Depot also contributed to Dow gains. On 15 October, the Dow Jones climbed 1.1 per cent or 550 points, while the S&P 500 gained 0.3 per cent and the Nasdaq Composite just managed to reverse its initial losses and closed with a gain of 0.1 per cent.

The sector rotation was clear-cut: Energy led the gainers list with a five-day gain of 6.07 per cent, followed by consumer staples with 5.20 per cent and healthcare with 4.10 per cent. These three sectors moved in sync, suggesting that capital was actively being rotated from growth into investments perceived as more resilient.

Increased uncertainty and changing risk appetite

The VIX volatility index rose 9.47 per cent over a week to 16.87 points. An increase of this magnitude signals that options traders are expecting more uncertainty, although the level does not yet indicate panic. A cautiously assessed market regime with a reading of 42.0 suggests that while the market is not in a downtrend, risk appetite has noticeably diminished.

Particularly telling was the underperformance of the Russell 2000. When this index lags significantly behind the Dow Jones, it signals a retreat from companies that depend on a healthy, credit-friendly domestic economy.

Inflation pressure and monetary policy

The wholesale price index recorded its strongest monthly rise since 2022, partly driven by elevated energy costs. Consumer price inflation continues to stubbornly exceed the US Federal Reserve's two per cent target. Geopolitical tensions from the US-Iran conflict have heightened cost pressures throughout the economy.

The CME Group's FedWatch tool shows an 85 per cent probability that the Federal Reserve will leave rates unchanged. Restrictive monetary policy typically weighs more heavily on growth-oriented technology stocks, whose valuations depend more heavily on future earnings, while companies with stable cash flows and dividends are less sensitive.

What the rotation means for investors

The combination of rising VIX, cautious market regime, underperformance of small-cap stocks and the rotation from technology into energy and consumer staples points to a shift in positioning. The market is currently not oriented towards acceleration. Sector rotations with this conviction tend to last longer than a week.

The divergence between the Dow and the Nasdaq reflects a broader defensive reallocation. Investors are reducing their exposure to highly valued growth segments. As one observer noted on 14 October, as the Dow traded nearly flat and the Nasdaq fell two per cent, the move looked like a rotation out of the most crowded growth positions, with the blue-chip industrial and financial stocks that dominate the Dow largely unscathed.

For investors in the German-speaking world who hold US stocks in their portfolios, this means: defensive Dow components with stable business models, consistent dividends and lower dependence on growth narratives could prove more resilient in an environment of elevated inflation and restrained monetary policy than highly valued technology stocks. Those with broad exposure to US indices should review the weighting between growth and value-oriented positions.
