Reuters - Asia stock-price indexes were up in the early running Wednesday after upbeat Wall Street earnings and optimism about an international recovery supported sentiment, although concerns about the sustainability of a recent risk rally are likely to cap gains.

The Australian S&P/ASX 200 Index was last up 0.5% and e-mini futures for the S&P 500 rose 0.14%. Japan's Nikkei 225 slipped 0.31%.

Bitcoin, which gained 19.5% Monday, was down 0.1% at $46,354 as Asian trading got underway.

The cryptocurrency was headed toward $50,000 Tuesday, but paused at $48,216.

The early action came as shares of Lyft, Inc. rose as much as 11% while Twitter, Inc. climbed 2% in aftermarket trading on their latest quarterly results.

The earnings follow a slowdown in the international market rally Tuesday as market participants reconsidered how much government stimulus spending, easy money from central banks and vaccinations will boost stocks, oil and inflation.

"Substantial inflation worries are potentially overblown," Stephen Innes, chief international markets strategist at financial services company AxiCorp Financial Services Pty. Ltd. said.

On Wall Street, the main stock indexes closed little changed, though Nasdaq composite hit a record on a gain of 0.14%. The S&P 500 lost 0.11% and the Dow Jones Industrial Average lost 0.03%.

The S&P had climbed the previous six sessions and is up 5.3% for the month. All three indexes closed at records Monday.

Indexes in Europe also slipped with the Stoxx600 index finishing 0.1% in the red. The index has gained nearly 4% this month.

The dollar index fell 0.57% Tuesday, led by losses against the yen and euro in choppy trade and hitting two-week lows.

The yield on the benchmark U.S. 10-year Treasury notes was last at 1.16% after rising Tuesday as high as 1.72% but falling back to the same level as Monday.

Brent oil rose Tuesday to $61.06 in the seventh straight session of gains, touching 13-month highs. Market participants are betting that fuel demand will rise while the Organization of the Petroleum Exporting Countries and allied producers keep a lid on supply.

"With Brent over $60, it's been great psychologically," said John Kilduff, partner at Again Capital LLC in New York. "Everyone is feeling bullish about stronger demand and international inventories in further decline."

Spot gold added 0.1% to $1,838.09 an ounce after rising to a one-week high Tuesday.

"The reflation trade is really starting to settle in," and gold is benefiting from the dollar weakening again, and stimulus being the big focus, said Edward Moya, senior market analyst at foreign exchange broker Oanda Corp.
