As a financial activity, not every investor can make a perfect investment, and there will always be regrets and disappointments among investors. However, taking stock, in order to make each fund investment closer to success, there are nothing more than the following five thresholds to be crossed. First of all, emotional barriers. Everyone is easily disturbed and influenced by the external environment. In fund investment, it is easy to catch up with the increase in fund net value and snap up new funds; The decline in net worth leads to the herding effect of redemption. All these have invisibly influenced people's investment ideas, thus prompting investors to change their original investment behavior. Therefore, it is very necessary for investors to make necessary psychological adjustments, update their ideas and analyze the market in advance, and give guidance before investing, which is the basic measure to alleviate the impulse of fund investment. Second, financial obstacles. The key factor that determines the success or failure of fund investors' investment is the time of fund subscription (application) and redemption. And it is necessary to effectively control the use of funds. First, it is required to hold fund shares for a long time, and the funds must be idle. Second, there is a shock adjustment during the growth of the fund's net value, and there are enough idle funds to adjust positions. All the above factors are necessary to ensure the smooth completion of the fund investment plan. Third, the risk threshold. This is something investors should always remember. As an investment activity. The high return of the fund must contain high risks. The asset types of different fund products are completely different, which determines that investors should have certain risk management and control capabilities before choosing fund investment. In this way, investment will not be passive, or even caught off guard. Fourth, the income threshold. Reasonable income expectation and reasonable income realization plan are helpful for investors to make reasonable investment decisions on the basis of comprehensive consideration of the overall income level of the fund. For example, money market funds mainly invest in short-term monetary instruments. When choosing this investment product, investors should moderately lower their expectations of high returns and pay attention to the management of idle funds that ensure sufficient liquidity. The stability and limitation of the net growth of bond funds also determine that investors can't blindly compare the income with the stock funds with faster appreciation. Fifth, the operating threshold. Fund as a long-term investment tool. Only by avoiding frequent operations can we maintain the stability of the fund's net value and the growth of the fund's income. Frequent operation of funds will reduce the profit space of fund products to a certain extent and limit the income obtained by investors. Therefore, it is very important for investors to maintain a correct operating mentality.
