The screen moves by the second. The business moves by the year.

Three of our holdings moved hard this week. ASML dropped on a soft China comment. Vertex slid on a slow product ramp. Neither changed a thesis.

That gap, between what the screen does and what the business does, is the whole game. Holding it steady is the entire job.

Here is the week in full: where the market sits against 75 years of history, the performance grid, each model's strongest and weakest holdings with the context behind them, the positions we are watching closely, the trade activity, and an essay on the lever almost no one discusses, position sizing. We watch everything, every day. We trade only when the process says to. That restraint is a decision, renewed weekly, and it is the hardest discipline in this business.
