Large-cap stock fund refers to the fund's investment portfolio with stocks with large circulation as the target. Similarly, the blue-chip market is based on large-cap stocks with relatively good performance, but now in the market, the so-called large-cap stocks and blue-chip stocks are relative, and there is no fixed standard, so funds may not really only buy stocks shown in their names. The same is true of military funds, mainly aviation, aerospace, ships, communication information and so on.
