The First Harvest

Monthly return: +1.11%

Dear Investors,

I have been a value investor for most of my adult life. The people who shaped my thinking about capital allocation (Mohnish Pabrai, Guy Spier, the Buffett-Munger canon) taught me to look for businesses with durable competitive advantages, honest management, and prices that offer a margin of safety. That framework has served me well for over a decade. It is still the foundation of everything we do at Workflow Capital.

About ten years ago, I noticed something that nagged at me. The same principles that made value investing work (patience, discipline, probabilistic thinking, buying when others are fearful) seemed to apply even more directly to options. Specifically, to selling them. An option is a contract on time and fear. The buyer pays for protection against something dramatic happening before expiration. Most of the time, nothing dramatic happens. The premium decays. The seller collects.

I traded options for a while back then. I understood the thesis, but I lacked the infrastructure. My trades were discretionary, influenced by the same emotional biases that every value investor learns to recognize in stock picking. I stepped away because I did not yet have the tools to execute it properly. The thesis was sound. The operator was not ready.

For the better part of a decade, I built software systems. Healthcare platforms, enterprise automation, AI-powered tools that processed millions of transactions. The work taught me something that Pabrai and Spier taught in a different context: the difference between a process and a prayer. In software, a system either works or it does not. You build it, you test it, you monitor it, and you let the machine do what machines do best: execute without emotion.

Last year, I decided to combine both worlds. The value investor's judgment with the engineer's discipline. The result is Workflow Capital.

The Farmer's Logic

We sell time. That is the entire business, distilled to three words. Every option contract is a small insurance policy. The buyer pays a premium today for the right to be protected against something that might happen tomorrow. We are the insurance company. We collect the premium, assess the risk carefully, diversify across many policies, and trust that over a large enough sample, time is on our side.

A farmer does not agonize over whether next Tuesday will rain. He plants in good soil, tends the crop, and accepts that some seasons are better than others. December was our first planting season.

The Numbers

We executed 19 trades in December. 18 of them expired profitably. One was closed early at a small loss when the thesis changed. That is a 95% win rate, and while I want to be careful about reading too much into a single month, the result came from selection. Every one of those 19 trades passed through a four-layer quality filter that examines financial health, momentum, and fundamental quality before a single dollar is risked.

The positions spanned technology, specialty chemicals, and consumer sectors. All were cash-secured puts on companies we would be comfortable owning, companies that would pass muster with any value investor. The monthly return was +1.11%.

I will not pretend that 1.11% sounds exciting. It does not. But compounded monthly, that pace produces roughly 14% annualized. And it was achieved in a partial month, with conservative position sizing, on a brand-new system with training wheels still on. More importantly, it was achieved with a maximum drawdown of essentially nothing. We knew our worst case at all times, and the worst case never came close to materializing.

The Infrastructure

What I am most proud of this month is the system underneath the return. Before a single trade was placed, we built: a five-gate execution protocol that validates every order before submission. A quality filter that screens hundreds of stocks down to a handful of candidates. Safety controls that physically prevent the system from placing market orders, taking on leverage, or exceeding position limits.

This is what I mean when I say this time is different. A decade ago, the decision-maker and the executor were the same person: me. A human who gets excited, gets scared, and occasionally convinces himself that "this one is different." Now the decision-maker is still me, drawing on the same value principles I have always followed. But the executor is a machine. I choose the strategy. The machine enforces the discipline. Pabrai often says the key to investing is to not be stupid. The machine makes it much harder to be stupid.

What Comes Next

December was proof of concept. The system works. The infrastructure holds. The thesis (that volatility is systematically mispriced and can be harvested by patient, disciplined sellers who understand the businesses underneath) produced its first small crop.

In January, we will scale. More positions, wider diversification, and the first real test of how the system behaves under higher volume. I expect mistakes. I welcome them. Every mistake the system catches is a mistake I would have made on gut instinct a decade ago.

The goal is to build a machine that is right often enough, manages risk always, and compounds quietly while we sleep.

Thank you for your trust. We are just getting started.
