1. There is no financial concern for infrastructure stocks. The amount of funds is a very important factor that determines the rise and fall of stocks. Without funds, it is difficult for stocks to rise.

2. The stock market value of some infrastructure projects is too large, and it is difficult for stocks with large market value to attract funds in and out. Promoting stocks requires a lot of money, and the main players generally don't choose such stocks.

3. No matter whether the industry is booming or not, infrastructure belongs to cyclical stocks. Only when the industry profits increase or the national economy is in a booming stage can stocks rise, otherwise it is more difficult for stocks to rise.
