This mindset treats successful investing as a behavioral discipline supported by Stoic and contemplative tools. Equity returns are available partly because investors must endure periodic losses, yet knowing that fact does not make fear easy to resist. Before investing, the individual establishes a sufficiently long horizon and accepts volatility as part of the arrangement. During stress, attention shifts from uncontrollable prices and forecasts to controllable actions: position sizing, research, saving, and adherence to a sound process. Meditation supports calm awareness, while journaling exposes recurring emotional patterns and preserves the reasoning behind decisions. The resulting pause between fear and action makes it easier to assess the thesis rationally rather than selling simply because wealth feels threatened.
Origin
Samantha McLemore connected investing behavior with Buddhism and Stoicism after practicing meditation, journaling, and exchanging Stoic quotations with Bill Miller during the pandemic. Extracted from Masters in Business.
Core principles
- 01Behavior often matters more than analytical knowledge
- 02Periodic losses are the price of equity returns
- 03Focus attention on what is within your control
- 04A long horizon makes volatility more tolerable
- 05Calm can be developed through deliberate practices
How to run it
- 1
Establish financial capacity
Invest only capital that can remain committed through a prolonged decline. Match equity exposure to liquidity needs and the ability to tolerate loss.
Pro tip Separate near-term spending reserves before defining the investment horizon.
Watch out A philosophical commitment to patience cannot replace adequate liquidity.
- 2
Accept the return bargain
Recognize that periodic losses are one reason equities can deliver superior long-term returns. Write down the drawdowns that the strategy may reasonably experience.
Pro tip Review historical declines before investing rather than during a panic.
Watch out Accepting volatility does not mean ignoring permanent business impairment.
- 3
Separate control from noise
List the factors you can control, such as research quality, diversification, costs, and behavior. Stop treating market prices or economic forecasts as controllable inputs.
Pro tip Use a two-column control exercise when anxiety rises.
Watch out Do not use acceptance as an excuse to avoid necessary portfolio changes.
- 4
Create a calming practice
Use meditation or another regular attention practice to notice fear before acting on it. The objective is not to eliminate emotion but to prevent automatic decisions.
Pro tip Practice during ordinary markets so the skill is available during a crisis.
Watch out Beginning only after panic arrives makes the technique less reliable.
- 5
Journal the decision
Record the thesis, risks, expected horizon, and emotional state before buying or selling. Compare later actions with the original reasoning.
Pro tip Include explicit conditions that would invalidate the thesis.
Watch out A journal becomes rationalization if entries omit disconfirming evidence.
- 6
Reassess calmly
During a decline, distinguish a lower price from a broken thesis. Act only after reviewing fundamentals, horizon, and predetermined invalidation conditions.
Pro tip Insert a cooling-off period when no urgent solvency or fraud risk exists.
Watch out Delay can be costly when new evidence reveals permanent loss.
In the wild
An investor sees a diversified equity portfolio fall sharply during a recession scare. Instead of selling, the investor checks liquidity, reviews each thesis, journals the emotional reaction, and confirms that the long-term assumptions remain intact.
→ The investor avoids converting temporary volatility into a permanent loss.
During the pandemic, McLemore meditated, kept a journal, and discussed Stoic ideas with Bill Miller. Those practices offered structure for separating uncontrollable events from investment decisions that remained within her control.
→ A calmer process for making decisions during extraordinary uncertainty.
Common mistakes
Confusing knowledge with behavior
Knowing not to sell during a decline does not prevent an emotional reaction when personal wealth appears threatened.
Choosing an unrealistic horizon
Long-term discipline fails when the investor needs the money before the strategy has time to recover.
Ignoring genuine thesis breaks
Calmness should improve analysis, not justify holding a permanently damaged investment.
Is it for you?
Best for
Long-term investors who understand equities analytically but struggle to maintain disciplined behavior during drawdowns.
Not ideal for
Anyone who needs invested capital soon or lacks the financial capacity to withstand substantial temporary losses.
