Korea Investment Holdings' subsidiary Korea Investment Securities announced on the 22nd that it has introduced the Net Order Imbalance Indicator (NOII) service, the first of its kind among domestic securities firms, for auction information on the U.S. Nasdaq exchange.
NOII is an indicator used to predict the flow of supply and demand for orders before the start and close of regular trading. The Nasdaq auction is a type of auction system used to determine the opening and closing prices of Nasdaq. Although it can be compared to the concurrent bidding system in Korea, it operates as an independent market separate from general transactions.
NOII is provided from 5 minutes before the start of regular trading until the start time, and from 10 minutes before the close until the market closes. Expected auction prices, expected transaction volumes, and expected opening and closing prices of unexecuted orders are provided as references for making investment decisions.
A representative from Korea Investment Securities noted, "By comprehensively utilizing NOII information and order book data, investors will be able to make more precise judgments when investing in U.S. stocks," adding, "We will continue to expand services related to overseas stocks in the future."
