There are many question being asked daily by a lot of traders around the world, most of these questions are focusing on the best ways to get profits and to avoid or reduce the loss. This can be achieved by a good money management and risk management technique. A lot of techniques have been studied and published everyday.
Pareto law is the one of the best techniques which is applied in the trading system. For many events, roughly 80% of the effects come from 20% of the causes? This law is also known as the 80-20 rule, the Pareto principle. It is the law of the vital few and the principle of factor sparsity. The 80/20 Rule was discovered in 1896 by the Italian economist Vilfredo Pareto, which is why the Rule is also called the Pareto Law, the Pareto Principle, and the 80/20 Principle. Pareto discovered the odd balance when he examined that 20% of his peapods contained 80% of the peas.
This article discusses how you can apply the simple logic of 80-20, which indicates that 20% of the input and effort will create 80% of the output or success.
Are the numbers always 80/20?
No, the 80/20 numbers are just an example used to illustrate this odd relationship between small and large. In reality the numbers can vary from case to case but the main characteristic is that they are unbalanced and far off from 50/50.
For instance, an ice cream shop might get 60% of its profits from 15% of its regular customers. This is also a valid example of the 80/20 Rule at work.
Traders and people in general tend to believe that each unit of effort or resource has (almost) an equal relevance for success. However, the 80/20 Principle bursts this bubble and shows that the numbers are highly skewed.
