Broadly speaking, it refers to a certain amount of funds set up for a certain purpose. It mainly includes trust and investment funds, provident funds, insurance funds, retirement funds and funds of various foundations.

Bonds are securities issued by debtors such as governments, enterprises and banks in accordance with legal procedures in order to raise funds and promise creditors to repay the principal and interest on a specified date. Bond is a kind of financial contract, which is a creditor's right and debt certificate issued to investors when the government, financial institutions and industrial and commercial enterprises directly borrow money from the society and promise to pay interest at a certain interest rate and repay the principal according to the agreed conditions.

Stock is a certificate of ownership issued by a joint-stock company, and it is a kind of valuable securities issued by a joint-stock company to all kinds of shareholders as a shareholding certificate to obtain dividends and bonuses. Each share represents the shareholder's ownership of the basic unit of the enterprise. Every listed company will issue shares.

2. Income stability is different.

Generally, the return of stocks is uncertain before purchase, and the return of stocks is constantly changing with the change of profitability of listed companies. When the company has more profits, it has more profits, when the company has less profits, it has less profits, and when the company loses money. We will also lose money. Before we buy bonds, the yield has been completely determined, and we can get fixed interest after maturity.

There are many kinds of funds, such as index funds, stock funds, hybrid funds, bond funds and money funds, and their income stability is different. Index funds, stock funds and hybrid funds are mostly used to invest in stocks, and their income stability is as uncertain as stocks.

Bond funds, on the other hand, mainly invest in bonds, with relatively stable returns. Monetary funds mainly invest in some short-term monetary instruments, such as government bonds, central bank bills, commercial bills, bank deposit certificates, short-term government bonds, corporate bonds, etc. Although the income is uncertain, it is relatively stable and the risk is very small, which can be ignored.

So the rate of return will not be very high. The annualized rate of return of general money funds is between 3% and 5%, which fluctuates every day. Bonds can bring some interest income to investors, and their volatility is smaller than that of stocks. They are low-risk and low-yield investment products.

3. Different economic interests.

Shareholders of a listed company are shareholders of the company. They have the right to directly or indirectly participate in the company's operation and management, attend the shareholders' meeting, and own part of the company's ownership. Bondholders have no right to ask about the operation and management of the company, and bonds can only express certain creditor's rights to the company.

A fund is a product of a fund company that we subscribe for or buy. The fund company will use the raised funds to invest in stocks or bonds, so that we can get some income. When we buy a fund, we also have no right to interfere with any behavior of the listed company where the shares held by the fund are located, nor do we have ownership.
