Asian markets gain following Wall Street rally

June 30, 2026 (MLN): Asian markets traded mostly higher on Tuesday, extending the positive momentum from Wall Street after improving geopolitical developments boosted investor confidence.

Japan led regional gains, with the Nikkei 225 climbing 0.93%, while the broader Topix index added 0.40%. South Korea's Kospi advanced 1.34%, although the small-cap Kosdaq declined 0.59%.

Australia's S&P/ASX 200 traded largely unchanged, while mainland China's CSI 300 rose 0.51%. Hong Kong's Hang Seng Index was the regional underperformer, slipping 0.97%, according to CNBC.

The upbeat sentiment followed a strong overnight performance on Wall Street, where investors welcomed easing tensions between the United States and Iran.

The S&P 500 gained 1.18%, while the technology-heavy Nasdaq Composite rallied 2.07%.

The Dow Jones Industrial Average rose 306.63 points, or 0.59%, to close at a fresh all-time high above the 52,000-point mark for the first time.

The index was supported by a nearly 5% surge in Alphabet during its first trading session as a constituent of the Dow.

Investor sentiment improved after the United States and Iran agreed to suspend hostilities and allow commercial shipping to continue through the strategically important Strait of Hormuz, easing concerns over potential disruptions to global energy supplies and trade.

In after-hours trading, shares of defense technology company AeroVironment jumped around 19% after the company reported stronger-than-expected fiscal fourth-quarter results.

The company posted adjusted earnings of $1.84 per share on revenue of $642m, comfortably exceeding market expectations of $1.46 per share in earnings and $559m in revenue.

Market participants are also shifting their focus to upcoming U.S. economic data due later on Tuesday, including the May Job Openings and Labor Turnover Survey (JOLTS), the June Chicago Purchasing Managers' Index (PMI), and the latest consumer confidence reading, which could provide further clues on the strength of the U.S. economy and the Federal Reserve's policy outlook.
