Extended data:

The main purpose of financial investment is to obtain income, but there are many kinds of securities. Due to the different nature, duration and other factors, their income levels and payment methods are also different, which can be summarized into two categories.

1. Fixed-income investment: refers to the income that investors get from purchasing certain financial assets. Specify a certain rate of return in advance, and pay it regularly or at maturity, which will be fixed throughout the financial investment period, such as bank deposits, bonds, preferred stock investments, etc. This kind of investment is generally less risky.

2. Non-fixed income investment: refers to the income obtained by investors from purchasing a financial asset. The fixed rate of return is not determined in advance, and it is not necessarily paid on schedule, but changes with time, such as common stock investment. This kind of investment is generally risky, but it also has greater profit opportunities and higher returns.
