So, how do we eliminate emotion from our investing decision? We can't eliminate it completely but there are certainly tools that might help. One is to calculate the fair value of a common stock that you are investing in. I covered this plenty of times but basically, the fair value of an investment is dependent upon the streams of profit generated by it. In the long run, if company A earns more than company B, then company A will be valued more than company B.
For a company that is growing such as Google, you can incorporate its growth and calculate the fair value with growth. I have talked about this once and you are welcomed to check our commentary section.
I know I don't exactly give you the best solution to the problem. Emotion is hard to ignore. I am not immune to that. But following your emotion will cost you a lot of money. Just watch those investors that bought during the NASDAQ peak in 2000. Don't follow the herd and keep your focus on the fair value of your stock. You will do really really well. Humans are all emotional being. We do not always make decisions rationally. Emotion is part of us as investors. Investors might feel better towards stocks at certain point or they might feel that owning stocks are risky and avoid it at all cost.
