Ray Dalio On “The Rules Of The Game”

Хотя написано вроде давно было, но актуально похоже будет всегда.

1)  A deep understanding of the fundamentals so that pricing inefficiencies can be identified.
Principle number one is fairly self-explanatory. That said, a deep understanding of the fundamentals is something few investors, in today’s world of low-cost index funds, actually consider. Generating outperformance requires an understanding of how the markets are mispriced. There is no escaping the need to have a thorough understanding of the fundamentals so that one can sensibly assess what is cheap and what is expensive.
2) Focus.
To add value (outperform/generate a higher return than a passive or risk-free investment) you need to be a better player than your opponents. Thus, focus and a deep understanding of particular markets is essential. Markets are extremely competitive, and you should seek to make the most of your advantages
3) Perspective without data-mining.
It’s all too easy to go data-mining when you’re looking for a successful strategy. By data-mining or to put it another way, to go looking for what would have worked in the past, you will develop an incorrect perspective. Formulate a strategy and test it in all market environments and when it doesn’t work, understand why, don’t abandon the strategy when it loses. Having a sound fundamental basis for making a trade, and an excellent perspective concerning what to expect from that trade, are the building blocks that have to be combined into a strategy.
4) Strategy.
Developing a strategy is only the first step in trading. Knowing how to balance your bets based on different expected returns, risks and correlations is fundamentally as least as important. Managing an existing position requires a deep understanding of money management and probabilities.
5) Substantial resources.
In today’s world, the average trader has a wealth of data and computing power at their fingertips. Technology has radically advanced the average level of play, in markets as in warfare; it has served to widen the gap between the resource rich and the resource constrained players.
6) Independent opinions.
Dalio realised almost as soon as he got into the business that he needed to muster the best independent opinions possible about particular investments to make money from the markets.
7) Stress test.
Even today Bridgwater is built around a culture of openness. Dalio knows the importance of stress testing opinions to ensure they stand up under different scenarios. However, he doesn’t care much about others conclusions, only the reasoning that led to these findings.
8) Overconfidence.
Overconfidence can be a dangerous quality in this game. Remain wary of becoming overconfident and continue to gather information. Not only will this improve your knowledge of the subject but it will also reduce your risks of not knowing.
