开放式基金：定义与运作

中文段落：

开放式基金，又称为共同基金，是一种由基金管理公司发起并管理的集合投资工具。与封闭式基金不同，开放式基金在设立后，其基金份额总数并不固定，投资者可以根据市场情况和自己的投资需求，随时向基金管理公司申购或赎回基金份额。这种灵活的投资方式使得开放式基金在市场上广受欢迎。

开放式基金的投资策略灵活多样，既可以投资于股票、债券等金融产品，也可以投资于房地产、黄金等实物资产。基金管理公司根据市场环境和投资者的风险偏好，制定相应的投资策略，力求在风险可控的前提下实现资产的增值。

对于投资者而言，开放式基金提供了一个相对低风险的投资渠道。投资者无需具备专业的投资知识和经验，只需选择信誉良好的基金管理公司和适合自己的基金产品，便能够分享到专业投资团队的研究成果和投资经验，实现资产的稳健增值。

英文段落：

An open-end fund, also known as a mutual fund, is a collective investment tool initiated and managed by a fund management company. Unlike closed-end funds, the total number of fund shares in an open-end fund is not fixed after its establishment. Investors can purchase or redeem fund shares from the fund management company at any time, depending on market conditions and their own investment needs. This flexible investment approach has made open-end funds popular in the market.

Open-end funds offer a diverse range of investment strategies, investing in financial products such as stocks and bonds, as well as physical assets like real estate and gold. The fund management company formulates corresponding investment strategies based on market conditions and investors' risk preferences, aiming to achieve asset growth while keeping risks under control.

For investors, open-end funds provide a relatively low-risk investment channel. Investors do not need to possess professional investment knowledge and experience. By selecting reputable fund management companies and suitable fund products, they can share the research results and investment experience of professional investment teams, achieving steady asset growth.
