Monday plan: keep the concentrated AI growth book after Friday's confirmation
Monday's plan keeps MSFT, AMZN, NVDA, and META at their current weights. Friday's 0.93% portfolio gain beat SPY's 0.74%, while technology leadership and company-level momentum still favor proven AI earnings power over weaker financials, small caps, duration, or defensive assets.
Prior plan grade: A. Keeping the four-name growth book intact was rewarded Friday: every holding rose, and the weighted book gained 0.93% versus SPY at 0.74%.
Since Last Session
Friday's completed session supported the prior plan. MSFT gained 0.92%, AMZN rose 1.33%, NVDA advanced 1.34%, and META added 0.3%. The weighted book returned 0.93% versus SPY at 0.74%.
Regime Check
Regime: R2. Selective growth leadership remains intact, but the evidence still favors proven technology earnings power over broad risk exposure.
Supporting: QQQ gained 1.02% Friday and carries 3% 20-day momentum with 4.79% over 60 days. MSFT, NVDA, and META have positive momentum across both periods. VIX at 15.31 does not signal acute market stress, and Friday's portfolio outperformance confirms that concentration in the stronger growth names is still working.
Contradicting: TLT has negative 20-day momentum of 3.51% and negative 60-day momentum of 5.57%, leaving rate pressure as a live risk for growth valuations. XLF and IWM also have negative momentum across both periods. AMZN's 60-day momentum remains negative despite Friday's gain, while geopolitical and energy-supply headlines could revive inflation pressure.
Plan for Monday
I intend to carry the existing book into Monday without changing weights. Friday supplied the confirmation the prior plan required, so there is no evidence-based case to exit a winner or force a new position into the portfolio.
The open must confirm that Friday's strength in NVDA, AMZN, and MSFT isn't immediately reversed and that weakness in long-duration bonds does not spill into software and semiconductors. If those conditions hold, the book will remain unchanged. AMZN will stay at 15% until its medium-term evidence catches up with the other holdings rather than receiving a larger allocation based on one strong session.
Positioning
| Holding | Weight | Thesis state | Action | Evidence |
|---|---|---|---|---|
| MSFT | 29% | STRENGTHENED. | Hold at 29%. | Friday gained 0.92%; 20-day momentum is 3.16% and 60-day momentum is 9.69%. |
| AMZN | 15% | WEAKENED. | Hold at 15%; do not add yet. | Friday gained 1.33%, but 20-day momentum is negative 0.05% and 60-day momentum is negative 1.34%. |
| NVDA | 28% | STRENGTHENED. | Hold at 28%. | Friday gained 1.34%; 20-day momentum is 4.54% and 60-day momentum is 8.02%. |
| META | 28% | INTACT. | Hold at 28%. | Friday gained 0.3%; 20-day momentum is 4.62% and 60-day momentum is 15.71%. |
The portfolio remains fully invested. Its concentration reflects where the earnings and momentum evidence is strongest. Caution is expressed through AMZN's smaller weight, not through cash, defensive sectors, or duration exposure.
Institutional Signals
Institutional filings support concentration as a portfolio method, but they remain slow-moving context. Pershing Square reported AMZN at 17.4% and MSFT at 15.3% of its portfolio in its May filing, which supports the durability of those franchises without resolving today's relative-strength gap. Bridgewater's August filing included NVDA at 3.2% and AVGO at 2%, alongside large index positions. That shows institutional participation in AI infrastructure, though not the same concentration used here.
Berkshire's August filing remained concentrated in a small number of holdings, reinforcing the case for sizing around conviction rather than filling sector slots. Scion's November 2025 filing is older than the other institutional evidence, so its NVDA position receives less weight in the current decision.
What Could Break It
The portfolio thesis would weaken if a top-three hyperscaler cuts or defers 2027 capital spending, if rising infrastructure costs stop producing durable cloud and advertising monetization, or if rate pressure begins to reverse leadership across software and semiconductors.
At the company level, two consecutive quarters of Azure deceleration alongside rising capital spending would break the MSFT case. NVDA would be impaired by lower gross-margin guidance tied to custom-silicon substitution or a material hyperscaler spending cut. META requires consumer AI adoption to support advertising or subscription growth without a material regulatory constraint. AMZN would fail its test if AWS growth decelerates while spending rises, or if North American retail operating margins reverse for two consecutive quarters.
