Nextrade said on Feb. 9 it will adjust the number of securities eligible for trading execution to 650 starting Feb. 12 to respond to a sharp rise in trading volume amid a recent market rally.

According to Nextrade, the combined average daily trading volume at the Korea Exchange (KRX) and Nextrade (NXT) jumped about 41 percent, to 2.362 billion shares in late January from 1.675 billion shares in early January.

With Nextrade's share of trading volume rising sharply, it prepared a self-help measure to stably comply with trading limits.

Under the move, the 50 most-traded stocks will be excluded from execution.

Major excluded names include HD Hyundai Energy Solutions, HPSP, LG Display, NHN KCP, Koh Young, Daewoo Engineering & Construction, Daehan Electric Wire, Mirae Asset Venture Investment, Jeju Bank, Hanwha Life and EcoPro Materials.

The stocks will be excluded from Feb. 12 through the end of June.

Nextrade plans to skip its regular second-quarter revision to manage trading limits stably and keep the 650 stocks, excluding the 50 names, through the end of June. It plans to newly select the third-quarter list at the end of June.

A Nextrade official said it will closely monitor the daily trading volume ratio to comply with trading limits under the Capital Markets Act. The official said it will try to keep the list of eligible stocks as stable as possible to minimise inconvenience to investors.
