TOKYO, May 19 (Reuters) - Japan's Nikkei share average

reversed early gains to fall on Tuesday as technology

heavyweights tracked overnight declines in their U.S. peers,

even as positive data prompted investors to buy economically

sensitive stocks.

The Nikkei fell 0.64% to 60,429.76 by the midday

break, after rising more than 1% earlier in the session. The

index is set to fall for a fourth straight session.

The broader Topix rose 0.37% to 3,840.7.

"The market is trying to determine how much longer the

declines of U.S. technology stocks will continue," said Yugo

Tsuboi, chief strategist at Daiwa Securities.

"Investors also want to see the outcome of Nvidia ( NVDA ) earnings."

The Nasdaq and the benchmark S&P 500 closed lower on Monday

as investors took some profits in technology stocks.

Nvidia ( NVDA ), the world's most valuable company, is

scheduled to report results on Wednesday. The chipmaker was the

S&P 500's biggest index-point drag on Monday, falling 1.3%.

In Japan, chip-testing equipment maker Advantest ( ADTTF )

fell 4.76% to drag the Nikkei lower the most. Technology

investor SoftBank Group slipped 3.56% and chip-making

equipment maker Tokyo Electron ( TOELF ) lost 2.96%.

Memory maker Kioxia ( KXHCF ) fell 4.24%.

Fibre optic cable makers fell, with Fujikura ( FKURF ) and

Furukawa Electric ( FUWAF ) down 5.75% and 7.6%, respectively.

Value shares rose after data showed Japan's economy grew faster

than expected in the first quarter on solid exports and

consumption.

"The growth was led by consumption. The market confirmed the

strength of domestic demand," said Daiwa's Tsuboi.

Topix's value share index rose 0.62% against a

0.1% rise in the growth stock index.

Bank shares rose, with Mitsubishi UFJ Financial Group ( MUFG )

and Mizuho Financial Group ( MFG ) climbing more than

3% each.

Of more than 1,600 stocks on the Tokyo Stock Exchange's

prime market, 70% rose, 28% fell and 1% traded flat.
