LOF fund provides investors with the net value of the fund and the floor price fluctuating around the net value of the fund by adopting the trading mechanism of floor trading and OTC trading at the same time. If the floor price is different from the net value of the fund, investors will have the opportunity to arbitrage. (1) When the secondary market price of LOF is less than the net value, after buying LOF in the secondary market, it will be redeemed on the spot or transferred to the off-site for redemption; (2) When the secondary market price of LOF is greater than the net value, purchase LOF fund shares on or off the market, and then sell the obtained LOF shares (which need to be transferred to the market for off-market purchase) through on-market transactions. (The handling fee and time factor should be considered in actual operation. )
