Authorized participants (APs) take on the role of reception desk for requests from institutional investors for creation and cancellation (redemption) in the primary market. On investors’ demand, APs request to the collective investment company creation or redemption of ETF. APs facilitate ETF trading by requesting creation and redemption of ETFs, and try to match the market price to the NAV. To do this, more than one of the APs should make an agreement with the collective investment management company to be a liquidity provider of a product.
