A stock has a premium, which actually means that there is money after deducting various expenses and other expenses. People often say how much premium a stock has, that is, a specific price difference between a target price of a stock and its par price.
When trading at a premium, you need to consider:
First of all, we should try to estimate the real-time net value of the fund at the end of the session and monitor whether there are arbitrage opportunities. If you estimate in intraday trading, you need to estimate the direction of net value fluctuation from 10 to the closing stage, and also consider the current real-time position of the fund.
Secondly, do premium arbitrage when you have good expectations for the market, and try not to do it easily when the market falls.
Finally, transaction costs, including subscription rate and sales commission, should also be considered in premium transactions.
