Be a Better Investor: Recognize What's Important & Knowable

September 15, 2015


As the familiar rumble of the turbo-diesel burbled in front of the office, I knew Eddie was stopping by for his regular visit.

Eddie, known as “Mule” by his friends, has scratched out a living doing every job imaginable in the oilfield over the last 50 plus years. Although I am not sure of the origin of the nickname, he is stubborn enough to have earned it. 

With a cup of coffee in his hand, the leather-skinned seventy-five year old started firing questions. “What is the price of oil going to do?”

I told him I didn’t know and I’m not sure many people do know. I reminded him he was supposed to be the oil patch expert. He grinned. 

Mule then asked, “What is the Federal Reserve going to do with interest rates?”

Again, I replied, “I don’t know.”

The pace of questioning sped up as Mule inquired, “What is the Chinese economy going to do?”

I told him I didn’t know.

Sarcastically, Mule said, “I thought you were the guy with all of the answers. Why do I pay you if you don’t know anything?”

Mule was sounding like my wife who is convinced I know nothing and if I do know something, it is unimportant. 

I explained to Mule that he does not pay us to know all things, but rather specific things and to have the discipline to know which ones require attention. 

He squinted his eyes and said, “Like what?”

In the world of investing there are things that are important and unimportant and things that are known and unknown.

Mule rolled his eyes and said, “Thank you, Aristotle. When did you become a philosopher?”

I assured Mule that none of the great thinkers would call upon us anytime soon. However, it brought up a good point of finance logic in terms of how to focus ones efforts in managing money and life. 

Categorize the Data

To be a better investor, it's important to break down data into these four categories:

  • Known
  • Unknown
  • Important
  • Unimportant

This is especially important with the constant information overload we are all exposed to. 


For instance, I know the sun will set tomorrow. However, in terms of assessing investments, it is unimportant. Furthermore, most of the “news” the popular media produces each day is not important. As a good investor, I don't stress over what's unimportant.

With things that are knowable, but unimportant, it is best not to put much emphasis on them. 

Conversely, a tsunami hitting the Gulf Coast would be quite important. However, the timing of such an event is unknowable. With unknowable, but significant, events you recognize they can happen. As such you position yourself so unforeseen events don’t wipe you out

Mule listened and asked how this might affect him. 

I told him the latest out of Chinese economy, the Federal Reserve or the oil patch fall in the category of unknowable. Additionally, when it comes to valuing any business this data probably falls in the category of unimportant also. 

However, specifically to Mule the price of oil is very important to his industry. He agreed.

History tells us oil prices are volatile and have a nasty habit of dropping precipitously, often without warning, or logic.

To be a better investor, you must recognize this possibility exists and position yourself accordingly. In assessing this possibility, anyone exposed to the oil field realizes how important it is to use debt sparingly and live below one’s means.  

Mule leaned back in his chair and acknowledged he almost went bankrupt in the ‘80’s when the price of oil fell to $10 per barrel and he borrowed too much money. It was still a painful memory. 

Focus on What You Can Control

Mule cocked his head to one side and said, “So I pay you to intentionally ignore some things, drill down into things that are important, and insulate me from those that are important but we never know when they’ll happen.”

Mule had summed it up well.

In a world of uncertainty we need to concentrate on things we can actually control like spending, savings, and quality of life. Plan for bumps in the road like hurricanes, accidents, and even death. And learn to ignore the unimportant.  This kind of focus reduces stress and worry while allowing us to make better decisions in the process.
