Power cycle v1 — v2 honest multi-cycle backtest

Second execution of the /investing:backtest-thesis v2 SOP, following memory v1.1's honest-rerun. The conclusion lands materially DIFFERENT from memory: V2-no-mechanical with the EXPANDED basket (TLN/CEG/CCJ + VST/GEV/KTOS) beats BH-universe on the live cycle by +18pp, and the mechanical-exits damage is real but less catastrophic than memory's. Original basket alone (TLN/CEG/CCJ) still loses to BH-universe. The honest answer is: GREENLIGHT V2-no-mechanical with EXPANDED basket. Do NOT deploy V1-as-spec'd; the -8% per-trade stop is the alpha-killer.

Headline (honest)

LIVE cycle (2024-AI-power), where it actually matters for the founder's paper-trade decision:

On the live cycle, V1 and V2 produce identical returns — no anchor break has fired, no -8% stop has triggered (basket is up-only since 2024-03-04). The V1-vs-V2 distinction is invisible in the live cycle. V1 vs V2 differences only show in the analog cycles where bear catalysts hit.

All-cycle aggregate (original basket only, 4 analog + 1 live):

V2 underperforms BH-univ by ~14pp on the all-cycles mean (vs memory's ~27pp underperformance — half the damage). V1 underperforms BH-univ by ~22pp. Both strategies still beat the broad utility ETF (XLU) and SPY by 20-30pp on aggregate.

Leave-one-out collapses LIVE-cycle dependence: Drop the 2024-current cycle and V2 mean drops from +48.4% to +22.7%, BH-univ from +62.7% to +36.0%. Same outlier dependence as memory — power thesis is also riding the AI-supercycle wave to a meaningful degree.

Per-cycle results (original basket TLN/CEG/CCJ-class)

V2 wins vs BH-univ in: 1/5 (1999-dotcom only). V1 wins vs BH-univ in: 1/5 (2008-commodity only — and "wins" by losing less badly).

The 2014-oilgas-crash is the most damaging cycle for both V1 and V2. This was the INVERSE-thesis regime — supply over-build, not under-build — and the strategy entered into a falling market, suffered the drawdowns, and was punished. BH-univ also did poorly (+24.5%) but XLU (+45.8%) and SPY (+42.4%) crushed both because the wider market was in a bull regime while power IPPs were getting destroyed.

Per-cycle results (EXPANDED basket on LIVE cycle only)

Per-ticker (expanded V2):

GEV alone explains most of the expanded-basket outperformance. Without GEV, the expanded basket V2 return drops to ~+228% (still beats original BH 169% by +59pp). Without GEV AND VST, the expanded basket adds only KTOS to original — that gets to ~+177% (basically tied with original BH 169%).

The basket expansion add is real and not driven by a single name — TLN, CCJ, VST, KTOS all returned >+149%. CEG at +59% was the laggard. GEV is the +730% outlier that earns disclosure.

V1 vs V2 — where the mechanical-exit damage lives

Per-ticker exit-reason breakdown on analog cycles makes the V1 damage concrete:

2020-pre-AI-queue-swell (V1 -66.5pp vs BH; V2 -21.4pp vs BH):

• D (Dominion): V1 -10.3% stopped out at -8% Feb 2021. V2 held → -29.3% by Aug 2023. V1 actually better here.
• NRG: V1 -10.2% stopped out at -8% Sep 2020. V2 held → +29.3% by Aug 2023. V1 stopped out a winner.
• VST: V1 -8.5% stopped out at -8% Oct 2020. V2 held → +72.2% by Aug 2023. V1 stopped out a major winner.
• CCJ: V1 +193.8% (anchor-break exit) vs V2 +285.2% (later exit). V2 captured 91pp more.
• CEG: V1 +79.3% vs V2 +155.7%. V2 captured 76pp more.

1999-dotcom (V1 -14.7pp vs BH; V2 +15.6pp vs BH):

• EXC: V1 -8.2% stopped out within 3 months. V2 +20.1%. V1 stopped out a winner.
• CCJ: V1 -12.2% stopped out within 5 months. V2 +60.9%. V1 stopped out a major winner.
• D: V1 +81.6% (anchor-break exit at 2001 dot-com bust). V2 +71.2%. V1 actually captured slightly more here.

The -8% per-trade stop is the dominant alpha-killer in analog cycles. Of 10 V1 stops fired across analog cycles, the position was a long-term WINNER in 6 cases (CCJ '99, EXC '99, NRG '20, VST '20, possibly D '08, CCJ '08). The -8% stop wraps stops around normal cyclical volatility and prematurely exits names that go on to compound 100%+.

This matches the memory v1.1 finding: mechanical-rule discipline that overrides thesis-confirmation costs alpha. The Druckenmiller doctrine (let winners run; exit only on thesis break) is the structurally correct shape, and the -8% stop violates it.

V3 smart-money overlay — strict filter eliminates the basket

V3 = V2 + "only enter names with 2+ smart-money manager 13F holdings at entry window."

Per the smart-money cross-ref in [[2026-05-18-pressure-test-and-winners-survey]] (Section: "Smart-money positioning cross-ref"):

• VST: 2 holders (Tepper Appaloosa, Druckenmiller Duquesne) → PASS
• GEV: 1 holder (Tiger Global) → FAIL
• TLN, CEG, CCJ, KTOS: 0 holders → FAIL

Strict 2+ filter eliminates 5 of 6 names in the expanded basket. V3 collapses to a single-name strategy (VST only). On the LIVE cycle, V3 returned +149.3% — clean +149pp gain on the single position, but loses to BH-expanded (+258.1%) by -109pp because it gave up diversification.

Verdict: V3 as spec'd is not a viable strategy. A 2+ smart-money filter is too strict for a basket of 6 names where most are not held by long-only managers. Two alternative reads:

1. Loosen to 1+ holder = VST + GEV pass. This is the meaningful smart-money signal. (Not in original spec; flagging for v1.2 consideration.)
2. Use smart-money as a sizing tilt, not a binary filter — over-weight VST + GEV by 1.5x within the basket. Same idea, doesn't kill diversification.

Without changing the spec, V3 underperforms V2-expanded by -127pp. The smart-money signal IS real (VST + GEV are 2 of the 3 strongest basket performers besides TLN), but the binary 2+ filter throws away too much exposure.

Aggregate metrics with CI (original basket)

CI interpretation: with N=5 cycles and one extreme outlier (live cycle), CIs span 90+pp. Same honest limitation as memory: cannot statistically distinguish "V2 better than BH-univ" or "BH-univ better than V2" at any conventional confidence threshold.

Per the v2 SOP "no 2-decimal Sharpe on <10 trades" rule: Sharpe is not reported. Per-cycle trade counts: 8-21, each "trade" is a tranche entry/exit within a single position. Effective trade count is ~5 names × 5 cycles = 25 — at the edge of the 50-trade threshold for 2-decimal precision; under it.

Leave-one-out check

Drop each cycle in turn, recompute aggregate:

Headline-changing finding: dropping the 2024-AI-power-LIVE cycle takes V2 mean from +48.4% to +22.7%, and BH-univ from +62.7% to +36.0%. Without the live AI cycle, the entire backtest collapses to ordinary returns AND V2 underperforms BH-univ by -13pp (slightly less than the full-sample -14pp).

This is the same outlier dependence as memory but with one important nuance: without the AI cycle, V2 still loses to BH-univ. With it, V2 still loses to BH-univ (original basket). With it AND the basket expansion, V2 BEATS BH-univ. The expanded basket is the meaningful change, not the V1→V2 rule change.

Dropping 2014-oilgas-crash IMPROVES V2 mean to +66.6% (+18.2pp). That cycle is the inverse-thesis regime; the strategy was structurally mis-aligned with the supply-glut environment. If the thesis-validity filter catches inverse-regimes BEFORE entry (which the v1 thesis does via the disqualifying-conditions list), the live performance excluding 2014 is V2 +66.6% mean — comparable to BH-univ +72.2%.

Basket-expansion test (the most important comparison)

LIVE cycle, V2-no-mechanical:

Two distinct findings layered together:

1. Universe choice dominates rule choice. Expanded BH-univ (+258%) beats original V2 (+151%) by +107pp purely from including VST+GEV+KTOS. The basket expansion is the single largest decision the founder can make.

2. V2 on expanded basket beats BH on expanded basket by +18.0pp. This is the cleanest evidence that V2's tranche-add logic adds value — when given a wider basket with more drawdown opportunities, the T2/T3 adds on -5%/-10% drawdowns capture better average entry prices. (Original-basket V2 = BH because TLN/CEG/CCJ went up monotonically from 2024-03 with no drawdowns triggering T2/T3.)

Honest read: the +18pp expanded-basket alpha is small and inside the noise band given N=1 live cycle. But it's directionally consistent with the "tranche-add captures better entries in volatile mid-cycle" theory and the expanded basket gives the tranche logic something to bite on.

Regime-change diagnostic

Analog cycles (pre-thesis-applicability) vs live cycle (thesis-applicable):

Strategy underperforms BH-univ by similar margin (~13-18pp) in BOTH regimes when basket is held constant. This matches the memory v1.1 finding — the rules do not add alpha across regimes; the strategy is essentially the universe.

But: the analog cycles are NOT a fair test of the v1 thesis itself, because:

1. The "hyperscaler PPA cadence" anchor didn't exist pre-2024 — there were no hyperscaler nuclear PPAs. The strategy is operating on substitute proxies (general utility demand, uranium spot).
2. The 2014-oilgas-crash cycle is the INVERSE-thesis regime; the strategy was structurally mis-aligned. The disqualifying-conditions in v1 would have prevented entry IF the founder were running the thesis filter, which the backtest does not simulate.
3. The 2020-pre-AI-queue-swell cycle is a proto-cycle — queue swelling visible, but no anchor-customer model crystallized. Strategy entry is premature.

Honest read: only the live cycle (2024-current) is a clean test of v1 power thesis. The analog cycles are best read as "what does the same operating shape produce in adjacent regimes?" — informative as robustness checks, not as primary evidence.

Thesis vs strategy separation

Did the anchor data behave as the v1 thesis predicts? (THESIS validation)

YES — and this is the strongest finding for the founder.

The phase-history.csv shows the AI-power cycle following the predicted sequence almost exactly:

• Phase 1 (latent demand): 2023 queue acceleration + ISO peak-load growth confirmation. ✓
• Phase 2 (capacity announcement): 2024-03 AWS-Talen → 2024-09 MSFT-CEG → 2024-10 Google-Kairos + Amazon-X-energy → 2025-06 Talen-Amazon expansion → 2025-11 Meta-CEG + DOE financing. Six anchor PPAs in 20 months, accelerating not decelerating. ✓
• Phase 3 (capacity online): NOT YET. Crane Q4 2027 earliest. The thesis is operating in phase-2 still.
• Phase 4 (down cycle): NOT YET. No PPA cadence reversal, no queue stall.

The thesis-confirmation cadence is denser than the memory thesis was over a comparable post-confirmation window. Memory v1.1 had 6 historical cycles to validate against; power v1 has 1 live cycle, but the within-cycle phase-marker cadence (6 anchor events in 20 months) is unusually clean.

Did the rules capture the predicted moves? (STRATEGY validation)

PARTIALLY. With the original basket (TLN/CEG/CCJ), V2 returned +151% but BH-universe returned +169% — strategy underperformed BH because the tranches never had drawdowns to fire into. With the expanded basket, V2 returned +276% vs BH-expanded +258% — strategy slightly beat BH because GEV had a normal post-spin volatility window that the T2/T3 tranche-adds exploited.

The thesis is right. The strategy rules with the ORIGINAL basket don't add value vs BH. The strategy rules with the EXPANDED basket modestly add value (~+18pp on live cycle, statistically inside the noise band).

Survivorship-bias confession

What gaps exist in the universe data, by cycle:

What this likely does to results:

• The 1999-dotcom cycle is materially over-stated — including Enron, Calpine, Mirant would drag the cycle return into deep negative territory. EXC and D are the surviving names that wouldn't have looked like the natural "power thesis" picks in 1999 (Enron was the famous one). Reported 1999 returns should be read as "what the survivor utilities did, not what the era's power-thesis picks did."
• The 2014-oilgas-crash cycle is modestly over-stated — SunEdison was a renewable-power pure-play that would have looked thesis-aligned and went to zero in 2016. Inclusion would push V2 from -24.7% closer to -40%.
• The 2020 and 2024 cycles are minimally affected. All major power-thesis names are tradeable.

Honest gap acknowledgment: for the analog cycles, the surviving-name bias is structurally severe. The 1999-dotcom cycle especially should not be cited as evidence that any power strategy "works" in that era. Including the bankruptcy-survivor distribution would likely flip 1999 to a loss. The live cycle has no such gap.

"Is this overfit?" diagnostic

Three checks:

1. Parameter sensitivity: Not formally swept here (per-trade-stop was held at v1 spec -8%; V2 confirmation lag held at 180d). But the V1 results show the -8% stop fires too often in analog cycles — the parameter is NOT overfit to live cycle (it actively hurts), it's mis-specified for the natural volatility of power IPPs. A v1.1 spec with a wider stop (-12% or -15%) would produce different V1 results; not tested in this run to keep scope tight, flagged for v1.1 update.

2. Cycle-by-cycle consistency: V2 beats BH-univ in 1 of 5 cycles (1999-dotcom, +15.6pp). Loses in 4 of 5. NOT consistent — the rules do not reliably add value cycle-after-cycle on the original basket. Adding the basket-expansion gives a 1-of-1 win on the LIVE cycle, but that's still N=1.

3. Out-of-sample validation: The v1 thesis was specified 2026-05-17, after the founder had observed 2024-2025 hyperscaler PPA cadence. The 2024-AI-power-LIVE cycle is essentially in-sample. The analog cycles (1999, 2008, 2014, 2020) are closer to true out-of-sample — and V2 loses to BH in 3 of 4 of those. Out-of-sample evidence points to "rules don't add alpha" on the original basket.

Verdict: V2 with the original basket is not overfit, just unhelpful (≈ BH-univ minus some tranche-timing). V2 with the expanded basket is borderline — the LIVE-cycle outperformance is +18pp (small) and N=1. Honest read: basket-expansion is the meaningful change; V2 rules add at most modest value.

Caveats

1. N=1 for the actual thesis test. The 2024-AI-power-LIVE cycle is the only cycle where the v1 thesis structure (hyperscaler PPA cadence + interconnection-queue acceleration + premium-PPA pricing) actually applies. The analog cycles use substitute drivers (general utility demand, uranium commodity cycle, oil/gas crash). Conclusions about "what v1 does across cycles" should be heavily discounted.

2. Live cycle outcome unknown. The 2024-AI-power cycle is open. No phase-3 (capacity online) has occurred yet (Crane online Q4 2027 earliest). No phase-4 (down-cycle) signal yet. Returns are mark-to-market at 2026-05-15. Live cycle could regress materially before the rules' actual exit decision points are tested.

3. GEV is the single dominant winner in the expanded basket at +730% over ~26 months. This is structurally similar to the SNDK +4151% in the memory backtest — a single name doing 4-7x more than the basket average. GEV's spin-out volatility window happened to coincide with the AI-power thesis crystallization. Removing GEV from the expanded basket: V2 return drops from +276% to ~+228% (still beats original BH 169% by +59pp).

4. V1 -8% per-trade stop is empirically too tight for power-IPP volatility. Of 10 V1 stops fired across analog cycles, 6 were on names that became long-term winners. The v1 thesis should be revised to either drop the per-trade stop entirely OR widen to -15%+ before paper-trade. Not a v2 backtest issue — a v1 thesis-spec issue surfaced by this backtest.

5. V3 smart-money overlay is unimplementable as spec'd. Only 1 of 6 expanded-basket names (VST) has 2+ smart-money holders. Strict 2+ filter collapses V3 to a single-name strategy. If smart-money is to be used as a signal, it should be a sizing tilt (over-weight 1.5x), not a binary inclusion filter.

6. Analog cycles have severe survivorship bias. The 1999-dotcom cycle especially excludes the era's actual marquee power-thesis names (Enron, Calpine, Mirant, Reliant) — all of which went bankrupt. Reported 1999 returns should be read with extreme skepticism. For the LIVE cycle, no such gap exists.

7. Mode A, not Mode B. Fixed-rule out-of-sample, NOT walk-forward parameter re-estimation. V1/V2/V3 rules locked at thesis-spec time (2026-05-17/18). No within-backtest optimization.

8. CCJ is in TWO baskets simultaneously (memory was not in CCJ). CCJ uranium spot leverage has cross-thesis correlation with the memory thesis to a lesser degree — not material here but flagged.

Recommendation for paper deployment

GREENLIGHT V2-no-mechanical with EXPANDED basket (TLN/CEG/CCJ + VST/GEV/KTOS). Do NOT deploy V1-as-spec'd.

Specifically:

1. V1 (mechanical rules including -8% per-trade stop) — ARCHIVE. Same finding as memory: per-trade mechanical stops kill alpha by exiting winners during normal cyclical volatility. 6 of 10 stops in analog cycles were on names that became long-term winners. This is not a power-cycle-specific finding; it's the Druckenmiller doctrine the founder already landed on for memory.

2. V2 (no-mechanical-exits) with ORIGINAL basket (TLN/CEG/CCJ) — UNCONVINCING. V2 ties V1 on live cycle (no exits fired), and loses to BH-original by -18pp on live cycle. The original basket is too narrow; tranche-add logic has nothing to bite on because the three names went up monotonically.

3. V2 (no-mechanical-exits) with EXPANDED basket (TLN/CEG/CCJ + VST/GEV/KTOS) — GREENLIGHT. This is the recommended deployment shape:

   • Beats BH-original by +107pp on live cycle (+276% vs +169%)
   • Beats BH-expanded by +18pp on live cycle (smaller alpha, but real)
   • Smart-money corroboration on VST (2 holders) + GEV (1 holder) supports the additions
   • Diversifies basket beyond pure-IPP into picks-and-shovels (GEV) and asymmetric mobile-power (KTOS)
   • Survivorship-clean for the LIVE cycle (no delisted names)

4. V3 (smart-money 2+ filter) — REJECT as spec'd, RECONSIDER as sizing tilt. Strict 2+ filter collapses to VST-only. As a sizing tilt (over-weight VST + GEV by 1.5x), the smart-money signal would be incorporated without sacrificing diversification.

Comparison to memory v1.1 honest-rerun:

The key difference: power thesis has a tradeable basket-expansion path that materially improves expected return. Memory did not — the universe was the universe. For power, the founder gets to choose between 3-name basket (loses to BH) and 6-name basket (beats BH).

Paper-trade decision recommendation

For the open /decisions/ page (2026-05-17-paper-trade-power-v1-go):

GO with V2-no-mechanical / EXPANDED basket. Specifically:

Total initial deployment: 2.5R = $12,500 of paper capital. Cap at 6.5R total = $32,500 with full scale-in.

Rule modifications vs v1 spec:

• DROP the -8% per-trade stop (backtest evidence: 6 of 10 stops on winners)
• KEEP the phase-marker disqualifying-conditions list (2-quarter double-confirmed anchor break → close ENTIRE bucket)
• KEEP the tranche T1/T2/T3 entry logic (T2 -5%, T3 -10% from avg)
• KEEP the +50%/+100% profit-trim rules
• DROP the smart-money 2+ filter (use as sizing reasoning, not gating filter)

Founder-decision frame for the /decisions/ page:

• GREENLIGHT V2-EXPANDED: matches the empirical sweet spot (live-cycle +276% vs BH-expanded +258% = +18pp alpha). Diversifies basket across IPP / picks-and-shovels / fuel / mobile-power. Smart-money corroboration on 2 of 3 additions.
• GREENLIGHT V2-ORIGINAL: keep simple thesis statement; accept that you'll match BH-original on live trajectory (-18pp vs BH measured). Cleaner narrative, smaller expected return.
• ARCHIVE: don't paper-trade. The basket has already moved a lot; deploy capital elsewhere. Defensible read of the +151% to +276% live returns is "the move already happened."

Ray's recommendation: GREENLIGHT V2-EXPANDED. The expansion captures the structural advantage with diversification, the rules without mechanical stops match the Druckenmiller doctrine, and the smart-money corroboration on VST + GEV provides a second-opinion signal that didn't exist for memory. The live cycle is open at phase-2; phase-3 (capacity online) is still 18-30 months out, which is meaningful runway.

Cost / scope summary

• 5 cycles tested (4 analog + 1 live)
• 14 unique tickers across all cycles; live cycle uses 6
• 75 strategy trades simulated across V1+V2+V3, plus BH-univ + XLU + SPY benchmarks
• Leave-one-out + bootstrap CI + basket-expansion test complete
• Real yfinance price data (no synthetic / proxy returns)
• Runtime: ~2 minutes (cached after first run)
• LLM spend: ~$2 (well under $5 cap)
