Asian stocks traded higher Tuesday, after expectations for continued low interest rates helped U.S. and European markets stage broad rallies overnight.

The Nikkei was up 1.1%, extending its sixth straight winning session yesterday. Helping the region's stocks was a turn in attention away from geopolitical issues toward a speech by U.S. Federal Reserve Chairwoman Janet Yellen on Friday. On Monday, the Dow gained 1.1%, after an index of U.S. home builder sentiment rose more than expected in August.

"U.S. economic data--including the latest home builder sentiment numbers--continue to support a strong equity market and a stronger dollar; Japan shares, especially tech exporters, are simply reflecting the more favorable currency market," said Yoshihiro Okumura, general manager at Chibagin Asset Management.

The dollar was roughly unchanged at Yen102.59 compared with Yen102.5 late Monday in New York. However, the pair may come under pressure in coming weeks if Ms. Yellen signals that the U.S. isn't in a rush to raise interest rates.

Investors in Japan are also looking to foreign trade data from the country out Wednesday to move markets. They expect higher exports and weaker imports to improve the country's trade balance.

Australia's S&P/ASX 200 was up 0.6%, ahead of corporate earnings of major firms like BHP Billiton Ltd. The company's capital management plans could give the broader market a leg up. Meanwhile, Toll Holdings jumped 5.8%, after cost-cutting measures helped the firm's profit rise 5.7% to A$298.5 million for the full fiscal year of 2014.

The Shanghai Composite Index ticked higher by 0.1% and Hong Kong's Hang Seng also rose 0.2%, as investors watched for earnings news. Bank of China, down 0.3%, is expected to report its earnings today, giving investors a gauge of the banking sector's health.

Elsewhere, Singapore's Strait Times was up 0.2% and South Korea's Kospi was up 0.8%.
