The Sunday Brief · where the market sits, one stock spotlight, one principle.
The market isn't broken. It's just behaving.
read three financial-media headlines this morning before I'd finished my coffee. One said the market was on the verge of breaking down. One said we were in a melt-up bubble. One said we were in a stealth bear that nobody was acknowledging. All three referenced the same week of trading.
This is the noise the Sunday Brief exists to filter. Each Sunday morning we publish where the S&P 500 actually sits relative to 75 years of historical data, what we're watching in the portfolios, and one idea worth sitting with for the rest of the week. Issue 1 sets the rhythm. The work itself is calm by design.
Three of four metrics in Normal territory. The market is closer to its average historical state than financial media suggests.
Three of the model portfolios ahead of the S&P year-to-date. BioTech 10 working through a sector pullback that has hit XBI similarly. We are not adjusting positioning.
ASMLASML Holding NV
There is one company on the planet that makes the machines required to manufacture the most advanced semiconductors in existence, and there are zero alternatives. The company is ASML. Every leading-edge chip in your phone, your data center, and the AI infrastructure currently being built was etched by an ASML machine. The list of competitors who could meaningfully threaten that position is a single empty page.
What financial media calls a "monopoly" is usually a temporary lead. ASML's position is structural. Their EUV lithography machines cost roughly $200 million each, weigh 180 tons, and require a decade of cumulative R&D to refine each generation. The intellectual property is split across thousands of suppliers, no one of which can recreate the system alone. China spent five years and billions trying to build an alternative and got nowhere. The moat is not opinion. It is geology.
ASML's order book typically runs three to five years deep, which is why the stock can dip 20% on a quarterly demand wobble while the long-term thesis is still intact. The 2024-2025 cycle was an instructive example. Shares fell on slowing China bookings, then recovered as TSMC and Samsung's leading-edge orders made up the difference. Investors who confused short-term order timing with long-term competitive position lost the patience trade. The patience trade was the right one.
ASML is held in Core 20. We did not buy it because of any particular quarter. We bought it because the structural position survives quarters that do not go to plan. That is the kind of business worth holding through the noise. Most are not. This one is.
“What feels like discipline at the moment of decision is usually the bias you most need to correct for.”
The disposition effect, restated
The disposition effect is the documented tendency to sell winners too early and hold losers too long. The reasoning at the moment of each decision feels disciplined. I am taking profits before they evaporate. I am not panic-selling on a temporary dip. Both narrations are reasonable. Both are usually wrong.
The data is unambiguous. Across decades of trading records, individual investors realize gains roughly 50% more often than they realize losses, while the underlying losses sit longer and grow. The behavior feels prudent. The performance penalty is real and measurable.
The defense is procedural, not motivational. A predetermined rebalance schedule. Position-size rules that trigger trims rather than judgment calls. A trading-blackout window that prevents the gut-decision sale. Discipline is not what you feel. It is what your process forbids you from doing.
