It depends on how much profit you want to earn . If you want a thorough result, you must synchronize in the short term. If you want a lot of time, you can work together for a long time. It's just a question of how you work. The final result will tell you how long and short. It's entirely up to what you need most at the moment.
When investing long-term, you are able to be more aggressive, so you could opt to invest in an aggressive mutual fund to get the highest rate of return. Determine the rate of return you want, then look for a mutual fund that averages that rate of return over a 5 to 10-year period. When you invest for the long-term you should not panic when stocks drop and you should not sell when the market looks bad.
short-term investments include money market funds, certificates of deposit, and short-term bonds. While many people try to play the market or speculate with "day trading," it is a risky business and you should educate yourself and do your research before you try short-term investments. For most people, it is easier, and safer to plan on long-term investments.
