The profit of the fund mainly comes from the rise of securities held in the portfolio and dividend income. However, the profit source of the fund does not include management fees and sales expenses.

Management fees are generally the fees charged by fund management companies, which are used to pay the daily operating costs of fund management companies, including fund operation, analysis and research, investment management and so on. Sales expenses refer to commissions or other remuneration obtained by sales personnel or agents through selling funds to investors. These expenses will be deducted from the fund assets, and investors should pay attention to the fund rate to ensure their final income.
