Process Investing
Process philosophy teaches a fundamental truth about reality: the world is not composed of static objects, but of dynamic processes in a constant state of flux. To view a business through this lens is to abandon the illusion that a company has a fixed identity or an eternal moat. While adopting this framework makes me a process investor at my core, the lens is only the method—it is not the destination. The ultimate goal is compounding.
True, massive compounding requires long-term duration, and finding those rare, durable businesses that can be held for decades remains the holy grail. Standard investing commentary often presents these businesses as static entities with everlasting moats. But process philosophy reminds us that reality is a sequence of continuous shifts, and general semantics warns that the map is not the territory—a past balance sheet, ticker symbol, or stock narrative is merely a static snapshot. This dynamic reality mirrors the ancient paradox of the Ship of Theseus: if every plank, nail, and mast of a ship is gradually replaced over decades, is it still the same vessel? A business operates the exact same way. Decades into an investment, the original founders are gone, the core revenue drivers have shifted, and the macro ecosystem has altered irrevocably. A ticker symbol gives the illusion of permanence, but the enterprise itself has been completely rebuilt. Process investing recognizes this truth: you cannot simply buy and forget, because holding over decades requires continuously re-underwriting a ship that is constantly replacing its own planks.
“The only constant is change. An investor who has all the answers to today’s questions has not even understood all the questions of tomorrow.”
Sir John Templeton
This perspective highlights why Warren Buffett’s ultimate thesis is entirely correct: buy-and-hold is the undisputed pinnacle of wealth creation. The overwhelming majority of Berkshire Hathaway’s value was generated by a tiny handcount of roughly 12 legendary, long-term decisions. Holding truly durable assets across decades is the only way to let the power-law math of uninterrupted compounding fully express itself.
Where the popular narrative strays is in assuming that achieving this is easy or passive. As Alice Schroeder illuminated in her book The Snowball, Buffett’s history is packed with active portfolio turnover, arbitrage, opportunistic trading, and exited positions. Far from contradicting his long-term philosophy, his turnover is irrefutable proof of how dynamic the world is, how rapidly conditions shift, and how excruciatingly hard it is to find a true keeper.
“In the 1930s, people thought railroad bonds were the safest investment in the world. Look what happened. You cannot simply buy a company and forget about it; the business landscape is always moving, and what seems permanent today is gone tomorrow.”
Irving Kahn
In a universe defined by continuous change, genuine multi-decade durability is exceptionally rare. Most businesses eventually succumb to technological disruption, competitive erosion, or strategic drift. Buffett’s activity level reflects a master allocator constantly testing the static map against dynamic reality, constantly filtering the market until he finds those rare businesses capable of surviving the gauntlet of time.
This reveals the central paradox every long-term investor must navigate. You must aim for ultra-long holding periods because exponential compounding requires uninterrupted time. However, the longer you own something, the more susceptible you are to competition, technological change, and events that reduce or eliminate the durability that was once present. A short-term trade rarely faces existential disruption, but a 20, 30, 40-year hold guarantees that a company will be thoroughly tested by market shifts and macro evolution.
“It’s not supposed to be easy. Anyone who finds it easy is stupid.”
Charlie Munger
Because long duration inherently exposes an asset to continuous change, you cannot compound wealth by standing still. You must respect the ongoing reality of change in order to protect the outcome you desire. This has led me to calling myself a process investor.
I approach the market with this framework in mind. First, the goal is immutable. I enter every position seeking deep durability with the explicit intent to hold for a lifetime. Second, I recognize that duration increases exposure to change, meaning durability is an ongoing process a company must defend, not a permanent state. Finally, adaptation protects compounding. Trading or exiting a position isn’t necessarily a failure of patience; often, it is a necessary alignment with reality when an underlying business process changes irreversibly.
By treating every investment as a dynamic process in a constantly changing world, we can bridge the gap between the idealism of long-term compounding and the harsh reality of constant change.
