Model events last 1 · after the close
Closed below 50-day Oct 20, 2026
SEI closed at $63.34, below its 50-day average ($64.18) after closing above it the day before.
Checks run on daily closes after the market close: a holding closing below its 50-day average, its trend label turning to Falling, or its weight drifting more than 25% from target. They describe the model; they aren't instructions to trade, and weights change only at dated rebalances.
How it works
What it is. A research model portfolio, not a rules-based screen: 28 stocks chosen after reviewing analyst consensus, price trend, volatility and drawdown, in two groups. Core (about 62%) holds lower and medium-risk names; a higher-risk group (about 38%) holds smaller positions in more volatile names. A few names are judgment picks held at small, capped weights. It is fully invested, with no cash.
Themes. AI hardware and platforms (capped at 46%), electricity and power generation, biotech, and defense.
How it is tracked. The live record starts at the Oct 21, 2026 close with the current 28 names and is compared with SPY. A first 20-name draft was revised before that close and has no live record. Between rebalances weights are not reset, so they drift with prices.
What can go wrong. It is concentrated in a few themes and includes several volatile, recently listed or pre-revenue companies. Picks made by judgment can share blind spots that a rules-based screen would not.
Universe: Hand-picked US-listed stocks.
Disclosures
The names were picked in Oct 2026 with what was known then, so any backtest of them would be hindsight-biased. Results count only from the Oct 21, 2026 close, compared with SPY.
Research only: a model portfolio for information, not personal advice and not an account anyone manages. Past results don't predict future returns.
Models can be wrong; holdings may be aggressive, speculative or out of date.
The author may hold positions in securities discussed here, including this model's holdings, and may buy or sell them at any time. See the disclaimer.
