Around the World's Markets: New York

WALL STREET chalked up its biggest gains in two weeks, led by computer-related companies including Adobe Systems, on optimism that earnings growth will lift share prices. The Dow rose 66.17 to 10,803.63, with American Express contributing a quarter of the advance.

The quarterly expiry of options and futures yesterday, or triple witching, which was seen as a factor behind much of the recent selling pressure, had a levelling-out impact, analysts said.
