Norway’s $890 billion fund, which considers high-frequency trading a scourge in global financial markets, is taking steps to avoid the practice as it spreads in Asia. The fund, which owns about 1.3 percent of the world’s equities, has already started to cut back on its use of algorithmic trading to dodge HFT traders who might be trying to pre-empt its moves in the U.S. HFT “is now gaining some momentum in Asia — we’re definitely following it and we have to do a lot of work on the individual markets,” said Oeyvind Schanke, head of asset strategies at the fund.
