There is no need to look at the K-line of the fund, because the fund is trading with your money. It is useless to look at it and you can't speculate. Only when you are familiar with it, if you operate funds in the short term, it is better to use stocks. Just pay attention to the movements of your fund manager.

Bubble analysis depends on the price-earnings ratio. Stocks have a net value, which is displayed on each stock. Speculation in stock trading is the expectation of the stock, which is the net value after one or two years. It may go further, but the economic development is not as high as expected, so the ultra-high par value of the stock is his bubble. There is a high risk at this time. If the economy declines, it is conceivable that this stock will exceed expectations, that is, its bubble will burst quickly and the face value of the stock will return to its net value. If everyone is no longer optimistic about expectations, the stock market will definitely plummet and people will be distracted. It's called a crash.

When it crashes, it is basically when prices rise and money is worthless. At the same time, hard currency is popular.
