Requires a certain amount of cash flow ability - I think this should be changed to a certain level of operational ability.

In 2008, the stock market oscillations intensified, and you can basically see what happened this month, with a sharp rise followed by a sharp fall. If you choose a fund with poor operability like an open-end fund, you will make money if it goes up, but then you will still lose money if it goes back down. Of course, I'm not saying that if it falls, it won't rise, but if you don't save profits when it rises, then it will fall back again next time, and you will take the elevator back and forth without making any money. And why do I say that the operability of open-end funds is too poor? Subscriptions and redemptions take 2 to 5 trading days to be credited, and the fees are too high. After redemption, you have to wait for more than a week for the funds to arrive before you want to buy at a low price. It is very easy to miss the opportunity and the fee rate is too high. You will not make much profit by tossing back and forth, so you can only hold it.

So I recommend that in 2008 it is best to choose closed-end funds, ETF funds and LOF funds with strong operational capabilities. The rates are low, purchases and sales are credited immediately, and it is easy to make swings.
