TOKYO, Oct 23 (Reuters) - Japan's Nikkei share average was
little changed on Wednesday, running out of steam after climbing
to a 10-1/2-month high, with weak chip-related stocks preventing
further gains after disappointing results from Texas
Instruments.
The benchmark Nikkei average .N225 eased marginally to
22,540.56 by the midday break, still near Thursday's high which
marked the best level since Dec. 3.
The broader Topix .TOPX added 0.1% to 1,630.15.
Tokyo-listed semiconductor-related shares were hit hard,
with Rohm 6963.T and Tokyo Electron 8035.T sliding 4.9% and
3.6%, respectively, as Texas Instruments TXN.O slumped nearly
10% in after-hour trading overnight.
The leading American chip designer on Tuesday forecast
current-quarter revenue well below estimates, in a fresh sign
that the global microchip industry is being squeezed by a
downturn in demand as well as a prolonged U.S.-China trade
dispute. The Nikkei heavyweight Softbank Group 9984.T shed 2.6% as
the tech conglomerate agreed to spend $10 billion to take over
U.S. office-space sharing startup WeWork on Tuesday, doubling
down on an ill-fated investment and paying off its co-founder
Adam Neumann to relinquish control. Eisai 4523.T was quoted up 18.1% at its daily-limit high,
still untraded with a glut of buy orders for the Japanese
drugmaker, after its partner Biogen BIIB.O revived plans on
Tuesday to seek U.S. approval for Alzheimer's treatment
aducanumab, which surprised investors and sent the U.S. pharma
firm's share up 27% overnight.
