If it is the operation of adding and lightening positions, you can choose to purchase and redeem, but it is recommended not to purchase and redeem frequently. The handling fee of OTC funds is very high, and people in the industry generally choose to buy ETF industry funds on the market.
If you are asking about the timing of adding and reducing positions, what is the good judgment basis?
The truth is to add positions on the way down. As long as there is no problem in the industry, the big opportunity is when the market is seriously discounted after the panic. This is the best time to buy assets.
When the market heat reaches a certain level, for example, when the aunt next door is talking about the stock market, she can lighten her position while rising.
