The math is unambiguous: a portfolio of equal-weight positions produces index-like returns. The only path to excess returns is concentrated positions in high-conviction ideas. For Dominion evaluating deals, the same logic applies: 10 mediocre deals is not diversification — it is certainty of mediocrity.

The act of writing a complete thesis — with specific assumptions, market size, timeline, catalyst, price target, and a clear definition of what would invalidate it — is itself a competitive advantage. The discipline of specificity identifies exactly where the thesis is weakest. For Dominion, every acquisition target should have a complete thesis document before the first conversation.

Focus on businesses with: (1) a clear path to a measurable catalyst within 18-36 months, (2) a durable competitive advantage not dependent on operational turnarounds, (3) a management team that can be influenced to execute, and (4) a capturable value gap large enough to justify the time and capital. Filter out businesses where the catalyst is "management will improve" — that is not a thesis, that is hope.

The fastest path to value creation in a complex company is often structural, not operational. Activism targets the capital structure: dividends, buybacks, spinoffs, asset sales, leverage changes. When a company's balance sheet is misallocated relative to its operational reality, the fastest and cleanest way to unlock value is to restructure the capital. Evaluate every target through the capital structure lens before the operational lens.

Every investment thesis should have a specific, named catalyst with a specific timeline. A catalyst is not "eventually the market will realize the value" — it is a specific event: a spinoff, management change, regulatory decision, strategic transaction, or shareholder meeting that will force a repricing. Without a named catalyst and timeline, the thesis is not actionable — you are speculating.

Ackman underwrites the downside before evaluating the upside. The question is not "how much can this win?" but "what is the maximum loss, what would cause it, and can I survive it?" This changes position sizing: the position should be sized so that the maximum loss is acceptable even if the thesis is completely wrong. The upside takes care of itself when the downside is bounded and the thesis is sound.

Markets are driven by narrative, not just fundamentals. The activist's job is to change the narrative, not just own the stock. Ackman publishes detailed presentations, engages with regulators, and builds public consensus around his thesis. For Dominion, the question of how to communicate the thesis to the market, regulators, and counterparties is not secondary — it is part of the investment thesis itself.

Every position has a lifecycle: (1) thesis construction, (2) building the position with defined entry points and sizing, (3) the catalyst event and repricing, (4) partial or full exit at target. The discipline is in knowing which stage you are in and managing accordingly. In stage 2, patience and position-building. In stage 3, holding through volatility until the catalyst lands. In stage 4, exiting on the timeline, not on the emotion.
