Regular fixed-amount investment is suitable for a very wide range of people. First, it is appropriate for individuals with regular fixed income. After deducting the daily living expenses from their fixed income, this group of people often have some surplus, but not in large amounts. At this point, a small regular fixed-amount investment method is most suitable. Specifically, without too much living pressure and also without too much savings, newcomers to the workplace are most suitable for regular fixed investments. As long as they set aside part of their monthly income to regularly purchase equity funds with good growth potential, through principal accumulation and compound interest returns, they will be able to achieve the goal of paying the down payment for their first home in about 10 years, laying a solid material foundation for building a happy and well-off life.
