Nasdaq hits record high despite 5.31% ten-year bonds: what investors must know now

The US stock market presented an unusual picture on 5 October 2026: while the yield on ten-year Treasury bonds climbed to 5.31 percent – the highest level since 2002 – the Nasdaq Composite reached a new all-time high of 27,477.31 points. The technology-heavy index gained 1.05 percent, while the S&P 500 rose 0.66 percent to 7,773.95 points. The Dow Jones Industrial Average gained 0.18 percent to 51,268 points.

Bond yields at 24-year high

The yield on ten-year US Treasury bonds rose on 5 October by three basis points to 5.31 percent, after 5.28 percent on the preceding Friday. As early as 1 October, it had reached 5.33 percent intraday, thereby exceeding the 2007 high. The yield on 30-year Treasury bonds has also reached its highest level since 2002. This development reflects persistent inflation concerns, strong economic data, and high issuance volumes of government debt securities.

Rising bond yields mean higher refinancing costs for companies and typically exert pressure on equity valuations – particularly for growth-oriented technology stocks, whose future cash flows appear less valuable at higher discount rates. The fact that the Nasdaq nonetheless closed at record levels signals extraordinary investor confidence in the technology sector.

AI optimism drives technology stocks

Several large corporations led market gains on 5 October. Nvidia rose 2.12 percent to a record close of 238.90 US dollars; market capitalisation moved close to 5.8 trillion US dollars. Microsoft gained approximately 2 percent after Melius Research upgraded the stock to "Buy" and issued a price target of 665 US dollars. Meta also posted gains.

PTC made the largest jump in the S&P 500, rising approximately one-third. The background was Schneider Electric's announcement that it would acquire the company for 22.6 billion US dollars in cash. The transaction is interpreted as evidence that the AI investment cycle is expanding beyond chip manufacturers and cloud computing providers to industrial software, automation, and infrastructure. Schneider Electric emphasised the growing importance of artificial intelligence in the industrial sector, digital twins, and engineering software for factory automation and energy management systems.

Why investors are ignoring higher interest rates

Analyst Luke Lango explained the apparent contradiction in market behaviour: "With persistently high interest rates and fuel costs burdening the broader economy, those market segments attract capital that can generate profit growth fast enough to overcome higher discount rates – and that is currently predominantly the AI complex." Raymond James strategists noted that performance is heavily weighted toward technology and energy, causing equal-weighted equity indices to lag behind benchmarks.

The stock market's ability to rise while ten-year yields remain above 5.3% underscores sustained confidence in technology earnings. Investors appear willing to accept higher refinancing costs as long as AI-related revenue, semiconductor demand, and corporate investment remain robust.

Sectoral divergence and risk factors

Not all market segments benefited from the rally. Real estate stocks were the only major S&P 500 sector posting losses on 5 October – evidence of this sector's particular sensitivity to high financing costs. Higher yields increase mortgage rates, corporate financing costs, and consumer credit, particularly burdening interest-rate-sensitive sectors.

Analysts view the elevated yields as a significant risk to the overall market. Investors are monitoring upcoming Treasury auctions, inflation reports, and statements from US Federal Reserve representatives for signals as to whether long-term refinancing costs can stabilise. A sustained rise in yields could put pressure on equity valuations – especially for growth stocks and the real estate sector.

Additional market factors

A decline in oil prices provided relief on 5 October. Brent crude fell approximately 1 percent to just over 101 US dollars per barrel after exports from Middle East producers increased and the G7 committed to releasing 100 million barrels of crude oil and diesel from their strategic reserves over the coming four months. Nothing has been released yet; analysts viewed the commitment as short-term relief amid persistent supply tightness. Lower energy prices dampened inflation concerns and supported market sentiment.

Assessment for investors

The developments of 5 October 2026 reveal a divided market dynamic: while the technology sector is buoyed by AI optimism, other areas are under pressure from elevated refinancing costs. The fact that technology stocks are reaching records despite rising yields suggests that investors currently view profit growth as strong enough to offset interest burdens.

However, this constellation remains fragile. Should AI-related revenue and corporate investment weaken or bond yields rise further, the valuation foundation for technology stocks could erode. The current market breadth – with heavy concentration in a few sectors – carries additional risks for broadly diversified portfolios.
