When the premium is too high, it is not cost-effective to buy in the market and it is easy to be attacked by the arbitrage army. You can apply, but the spread is too small to be worth it.
Premium is a term in the securities market, which means that the amount actually paid exceeds the par value or face value of securities or stocks. On the other hand, in the fund, it refers to the value that the transaction price in the closed-end fund market is higher than the net asset value of the fund unit.
You think too much. In less than 70 years, the house has already become a dilapidated building.
