Understanding First Principles in Trading 

First principles in trading involves breaking down complex concepts into their fundamental, indisputable components. Using this strategy, traders analyze the underlying principles that govern the market. They do not rely on analogies or existing models, which allows for a deeper understanding of the market dynamics.

For instance, instead of relying on historical patterns or market trends, a trader using first principles thinking analyzes the following:

  • Fundamental economic factors
  • Supply and demand dynamics, and
  • Macroeconomic indicators that drive asset prices.

First Principles Thinking is a Universal Approach

First principles thinking is a universal approach that extends beyond just trading. Innovators like Elon Musk are known for applying first principles thinking in various fields. Musk often breaks down problems to their fundamental principles to find unconventional solutions. 

For example, when developing SpaceX’s reusable rockets, he questioned traditional assumptions in the aerospace industry and reimagined rocket design from scratch.

The Falcon 9, SpaceX’s two-stage rocket, is the world’s first orbital-class reusable rocket. It is designed to transport both people and payloads into Earth’s orbit. Reusability allows SpaceX to refly the most expensive parts of the rocket. This technique substantially drives down the cost of space access. 

The Falcon 9’s reusability has been a game-changer, with some customers now preferring reused boosters over new ones. In doing so, Musk challenged traditional norms. The Falcon 9’s reusability has been a key factor in SpaceX’s efforts to revolutionize space travel and make it more cost-efficient.

How First Principles Thinking Steers Away from Analogies

Instead of just relying on analogies, traders use reasoning gained from first principles thinking. This helps them analyze market mechanics, make more informed decisions, and set up trades.

How Impactful Can First Principles Thinking Be in Trading?

Let’s understand this concept by considering a situation where traders notice heightened volatility within a particular industry.

Trader’s Reaction Traditional Approach First Principles Approach
The thought process Traders look at historical data of the sector during volatile periods.
  • Traders understand market mechanics and the underlying reasons for the volatility. 
  • They identify core drivers behind the volatility, such as:
  1. Shifts in supply and demand
  2. Technological advancements, or
  3. Global economic trends.
The action taken Traders apply strategies used in similar situations in the past.
  • Armed with a deep understanding of the sector’s fundamental drivers, the traders develop strategies that align with these unique factors. 
  • They adjust risk management protocols by:
  1. Choosing specific trading instruments, or
  2. Timing entries and exits based on the identified core drivers.


Exploring Market Mechanics Through First Principles 

Market mechanics refer to the underlying processes and structures that govern the functioning of financial markets. By applying the first principles approach, traders break down these market mechanics into their fundamental components. 

To understand this breakdown process better, let us explore some key elements of market mechanics:

    • Best Bid and Ask:
      • Instead of merely observing the bid and ask prices, traders using first principles thinking understand the fundamental concept of supply and demand. 
      • The best bid represents the highest price a buyer is willing to pay, while the best ask is the lowest price a seller is willing to accept. 
      • Analyzing these levels from first principles involves considering the following:
        • Dynamics of order placement and
        • Psychology of market participants.


    • Order flow represents the real-time buying and selling activity in the market. 
    • Traders employing first principles thinking:
      • Go beyond superficial analysis and
      • Analyze the reasons behind order flow changes.
    • This mainly includes finding answers to these questions:
      • How do large trades impact order books?
      • How do market participants react to the news? 
      • How can order flow signal shifts in market sentiment?
  • Microstructure:
    • Market microstructure involves the detailed analysis of how orders are executed. 
    • It also defines the role of market makers along with the impact of transaction costs. 
    • A first principles examination of microstructure includes understanding the rules and mechanisms that govern the market’s inner workings, such as:
      • Different order types
      • Market regulations, and
      • The role of technology in trade execution.
