Professional asset management is not just about picking the right investments and mitigating the risks that come with the investments. It is also about discipline. The purpose of investment rules or principles is that they avoid investment decisions being dependent on the mood of the investment manager. The rules and principles guide behavior, hence making this behavior more consistent and more predictable. The clearer the rules, the lesser the room for interpretation, the faster you can make investment decisions, the easier these decisions can be understood, and the less these decisions will—and even can—be disputed. Higher predictability of investment behavior benefits the transparency of the investment process.
