When comes to investment, there are a lot of factors that outside our prediction. I have 3 here to share.
1. Human Factors - When comes to money, there are a lot of party involved. So as your investments. For example, you invest in a stock and you know the price will raise. However, because of a mistake that made by the CEO, the stock price is going down unexpected. So this considered human factors.
2. Timing - Timing is very important for investing. When you want to invest and at what level you must exit and take the profit. This is what we always call entry and exit level. If you enter the market or exit at the wrong timing, you probably will drop down the profit or even lost in the investment.
3. Yourself - Yes, yourself is the biggest unexpected factor. Sometimes, our emotion is the hardest to control. When comes to money, we always bring along our emotion. And the funny thing is, emotion does always affect our decision making. Even you have your own investing plan or strategy, because of your emotion you will forget the plan and make your wrong decision. I experienced this before!
