The method, the reasoning, the evidence

How we did it — and why it holds

One page, three layers: the method that turned an open question into a portfolio (top), the reasoning behind every call this report makes (middle), and the evidence ledger that reasoning rests on, compacted (bottom). Every claim traces to the reaction map, the five strategies, or a dated source in process/3-analysis/aggregated-insights.md.

The method, end to end

Read it top to bottom. Where a step fans out, that's parallel work — 14 research dives across three batches, four portfolio buckets — merging back together.

The six goals we set

At each turn we set the AI one clear goal. In plain language:

Why the conclusions hold

For each call, the evidence it rests on, the logic that turns evidence into a recommendation, and the caveat that keeps it honest.

1 · Why the safe core can't beat inflation — and why there's now one exception

RO inflation cooled to 10.4% in June (from 10.9% in May), but core inflation (CORE2) ticked up to 8.5%, and the central bank's own end-2026 forecast is unchanged at ~5.5% — that forecast, not the spot print, is the right yardstick. Against it, every RON-safe instrument still falls short. The one exception: the Fidelis EUR 10y (R3607AE), tax-free under art. 93, pays a 6.20% coupon — the first line in this entire project that clears "beat inflation" after tax, in EUR, without equity risk. It's also, for now, a narrow exception: the only Fidelis tranche with a live two-sided order book, so it anchors every tier's bond floor as a single-issuer, single-tenor position, not a diversified one. The EU government-bond leg (XGLE) earns its place on liquidity and sovereign diversification, not yield. Net: a low-risk core still can't beat inflation on RON paper, so European equity must carry the growth mandate, with Fidelis carrying the floor. (I1, I2, I13; results 13/14.)

2 · Why European equity leads growth, not Romanian

The Bucharest index hit a fresh all-time high in July — but on ~60% energy-and-utilities concentration, thin, with a near-junk sovereign overhang. As the engine that would be a sector bet dressed as a country allocation, and it offers almost no diversification against the satellite's own energy and nuclear lines. Broad STOXX 600 / MSCI Europe UCITS (as cheap as 0.07% TER) are diversified and EUR-native, so they lead; RO stays a smaller satellite. US/AI exposure, where it's used at all, is reached through European-listed UCITS — the "no-US-venues" rule is about where you buy, not what a fund holds. (I16, I17; results 04/05.)

3 · Why the satellite leads with defense, not AI

Defense's fiscal case is funded and confirmed — Romania's €16.68bn under the EU's SAFE programme, NATO's 5%-of-GDP-by-2035 commitment — but its equity case de-rated hard this summer (Rheinmetall fell 13–18% in one session, Germany cancelled a frigate programme, a planned IPO was postponed). It leads the satellite as a diversifier, not a one-way tailwind or a hedge. AI/semis, by contrast, is real but extended after a historic melt-up, and — because a "diversified" European core is already ~18% tech by weight — an AI sleeve mostly falls with the core rather than against it. So the satellite is built defense-first and spread across several domains (energy, nuclear, financials, industrials, healthcare), with only one verified AI/semis line and nuclear capped at ≤3% to avoid double-counting the AI-power trade. (I6, I8, I10, I20; results 09/10/12.)

4 · Why all-in AI is only ~3.5–9.8%, when the ceiling is ~15%

This is the subtle one. Across all five strategies, netted all-in AI lands at ≈3.5% / 6.2% / 9.1% / 9.1% / 9.8% — the ~15% ceiling is not reached anywhere, and even Aggressive leaves ~5 points unspent. It is not that the mandate removed the instruments: the verified BT-buyable shortlist confirms three AI-capable routable lines (semiconductors, AI/tech thematic, a global-semis tracker) plus a European-tech line — the instruments to reach 15% exist and are buyable. The real reason is a judgement call about the AI bubble: the core already carries an estimated 9–13% of hidden AI exposure before the satellite adds any, and an AI-bubble pop hits core and satellite together, so the explicit AI line is sized small on purpose, not by rule. What actually shapes the five strategies, in order: (1) the platform fee grid (it sets how many lines a portfolio can hold, and forces five strategies plus one empty cell), (2) the ≤20% satellite cap on Defensive/Moderate (③/④ sit exactly at 20%), and only then (3) the ~15% AI ceiling — slack everywhere, kept as a guardrail against future drift, not a limit anything is bumping into today. If that bubble read is wrong, the ceiling permits roughly 5 more points and the instruments to buy it are already verified. (I20, I23, I25; bt-instrument-shortlist.md §4.4.)

5 · Why gold, cash and crypto were excluded — and what it cost

All three are excluded by mandate, not because the evidence turned against them — the universe for this study is strictly Romanian- and European-listed, full stop, and that scope decision removes them regardless of what they were worth. Stated honestly: gold was, on this project's own evidence, the cleanest diversifier available, and the only net-positive line in our own AI-bubble stress test. Crypto had already decoupled from gold and traded as tech-beta — amplifying, not hedging, AI risk — so it was a weak case even before the mandate. Removing them is a legitimate choice, but it has a real cost: the hedge stack against the sleeve's own concentration risk is thinner than the evidence-optimal version would have been. What is left to carry that load is look-through AI netting (question 4), the tax-exempt Fidelis anchor, and phased entry — not an orthogonal real asset. (I12, I14, I15, I21, I24; result 15.)

6 · Why ④ Balanced is the base case, and how to pick your cell

Pick your cell in two steps, capital first, then risk. Capital decides how many satellite lines you can afford: BT's per-order fee has a fixed component, so a small line costs several percent all-in to trade at the low end of the €20–90k band and a fraction of a percent at the high end — the same strategy expressed across more lines is strictly worse below roughly €40–50k. That is why Aggressive at small capital is deliberately left empty: at that size, spreading the satellite widely enough to earn Aggressive's exception to the 20% cap costs roughly double per line, which defeats the point of going Aggressive in the first place — that capital is better placed in ③ Balanced-Lite. Risk tier then moves the dials: the bond floor narrows from 46% to 8%, the satellite grows from 15% to 54%, and only Aggressive is allowed to fail "beat RO inflation" outright — stated plainly, not hidden. ④ Balanced (Moderate tier, larger capital) is the recommendation: a real European-equity engine, a capped defense-led satellite, netted AI near 9%. It's the setting to tilt away from — toward Defensive for stability, toward Aggressive once the themes prove out — not a number to commit to blindly. Full grid: Strategies →.
