Why it matters

This compares how strongly current model portfolios favor assets that had already outperformed. It describes the allocation and does not infer why the model chose it.

Live AI risk posture is risk-seeking

The newest live portfolios have a deterministic risk-taking score of 72.5 out of 100.

Risk-taking score is allocation-based, not performance-based: higher means more weight in growth, momentum, cyclical, and higher-risk assets.

Shared Model-Facing Prompt Packet 29,307 characters
# CapitalBench portfolio-v3.0 Task

You are participating in an offline, time-resolved CapitalBench evaluation round. Every model receives the same frozen information and makes one single-turn, non-agentic judgment without tools, browsing, retrieval, or follow-up.

Your objective is to rank assets for realized return over exactly one month and identify candidates that can beat SPY. CapitalBench, not you, constructs the scored portfolio from your judgment using the fixed rule below.

The deterministic candidate slate exists to prevent omission; it is not a recommendation. Assess every slate candidate. You may add at most two wildcard options from the complete allowed universe, but only when the frozen briefing supplies a specific reason the mechanical slate missed.

Use only facts and mechanical market data supplied in this input. You may use internal learned knowledge and general priors, but do not intentionally rely on facts, prices, news, or events after the research cutoff. Treat section order, mention count, option order, table order, and slate inclusion as neutral presentation choices rather than recommendation signals.

Do not extrapolate recent returns mechanically. A recent winner has no positive edge without independent in-window support. Give extreme recent losers a fair reversal test, but distinguish temporary price overreaction from fundamental deterioration. Use the supplied cross-sectional dispersion, medium-horizon relative strength, volatility, drawdown, volume, briefing evidence, and quality evidence. Optimize for the stated close-to-close scoring window only.

For every assessed candidate, provide probabilities and an 80% excess-return range relative to SPY. Rank every assessment without ties. top3_option_ids must be the options ranked 1, 2, and 3. prefer_spy is a diagnostic judgment and does not override the deterministic rule.

CapitalBench applies this rule after your response:

1. Preserve your candidate ranks.
2. A non-SPY candidate is eligible only when you label its recent return as overreaction and give it at least a 55% probability of beating SPY.
3. Select at most the first three eligible candidates in your rank order.
4. Fill fixed portfolio slots of 35%, 35%, and 30% in that order.
5. Put every unused slot in SPY.

You do not submit allocations or an alternative portfolio. Return only valid JSON. Do not include markdown, citations, prose, or commentary outside the JSON.

Research cutoff: September 21, 2026 at 04:22:50 UTC. Latest completed U.S. market session: September 18, 2026. Prospective entry close: September 21, 2026.

This briefing provides fixed factual datapoints only. It does not rank, recommend, analyze, or map facts to CapitalBench options. Inclusion, order, grouping, and row count are not evidence of expected return. A mechanical full-universe price, risk, and benchmark-relative appendix follows this briefing in the model input.

Price history is descriptive context, not a forecast.

## Equity markets

- On September 18, the S&P 500 closed at 7,650.50, up 0.2%; the Dow Jones Industrial Average closed at 51,682.64, down 0.2%; the Nasdaq Composite closed at 26,522.55, up 0.4%; and the Russell 2000 closed at 2,860.40, down 0.5%.
- For the week ended September 18, the S&P 500 fell 0.1%, the Dow fell 1.7%, the Nasdaq Composite gained 0.7%, and the Russell 2000 fell 1.5%. Most stocks declined on September 18.

## Industrial activity and labor

- U.S. industrial production was unchanged in August after a 0.2% increase in July. Manufacturing output fell 0.3%; mining rose 0.1%; utilities rose 1.8%; and total industrial production was 1.4% above its year-earlier level. The release is subject to revision.
- Capacity utilization was unchanged at 76.3% in August, 3.1 percentage points below its 1972–2025 average.
- In August, unemployment rates were lower in eight states and the District of Columbia and stable in 42 states. The national unemployment rate was 4.1%, unchanged over the month and little changed from a year earlier. Nonfarm payroll employment rose in four states and was essentially unchanged in 46 states and the District of Columbia.

## Rates and energy

- The reported 10-year U.S. Treasury yield was 5.00% on September 18 after topping 5% earlier in the week.
- Brent crude briefly traded below $102 per barrel before rising above $103 on September 18.

## Scheduled events

This briefing is a date-stamped factual snapshot. It does not state expected winners or translate facts into portfolio positions. The complete mechanical appendix that follows is descriptive rather than predictive.

# CapitalBench portfolio-v3.0 Task

You are participating in an offline, time-resolved CapitalBench evaluation round. Every model receives the same frozen information and makes one single-turn, non-agentic judgment without tools, browsing, retrieval, or follow-up.

Your objective is to rank assets for realized return over exactly one month and identify candidates that can beat SPY. CapitalBench, not you, constructs the scored portfolio from your judgment using the fixed rule below.

The deterministic candidate slate exists to prevent omission; it is not a recommendation. Assess every slate candidate. You may add at most two wildcard options from the complete allowed universe, but only when the frozen briefing supplies a specific reason the mechanical slate missed.

Use only facts and mechanical market data supplied in this input. You may use internal learned knowledge and general priors, but do not intentionally rely on facts, prices, news, or events after the research cutoff. Treat section order, mention count, option order, table order, and slate inclusion as neutral presentation choices rather than recommendation signals.

Do not extrapolate recent returns mechanically. A recent winner has no positive edge without independent in-window support. Give extreme recent losers a fair reversal test, but distinguish temporary price overreaction from fundamental deterioration. Use the supplied cross-sectional dispersion, medium-horizon relative strength, volatility, drawdown, volume, briefing evidence, and quality evidence. Optimize for the stated close-to-close scoring window only.

For every assessed candidate, provide probabilities and an 80% excess-return range relative to SPY. Rank every assessment without ties. top3_option_ids must be the options ranked 1, 2, and 3. prefer_spy is a diagnostic judgment and does not override the deterministic rule.

CapitalBench applies this rule after your response:

1. Preserve your candidate ranks.
2. A non-SPY candidate is eligible only when you label its recent return as overreaction and give it at least a 55% probability of beating SPY.
3. Select at most the first three eligible candidates in your rank order.
4. Fill fixed portfolio slots of 35%, 35%, and 30% in that order.
5. Put every unused slot in SPY.

You do not submit allocations or an alternative portfolio. Return only valid JSON. Do not include markdown, citations, prose, or commentary outside the JSON.

Required JSON format:

- evidence must refer only to supplied input and contain no URLs;
- key_risks must contain 2-5 concrete risks;
- do not output portfolio allocations, a second ranking, a financial-advice disclaimer, or extra fields.

# Market Briefing — September 21, 2026

Research cutoff: September 21, 2026 at 04:22:50 UTC. Latest completed U.S. market session: September 18, 2026. Prospective entry close: September 21, 2026.

This briefing provides fixed factual datapoints only. It does not rank, recommend, analyze, or map facts to CapitalBench options. Inclusion, order, grouping, and row count are not evidence of expected return. A mechanical full-universe price, risk, and benchmark-relative appendix follows this briefing in the model input.

Price history is descriptive context, not a forecast.

- For the week ended September 18, the S&P 500 fell 0.1%, the Dow fell 1.7%, the Nasdaq Composite gained 0.7%, and the Russell 2000 fell 1.5%. Most stocks declined on September 18.

This briefing is a date-stamped factual snapshot. It does not state expected winners or translate facts into portfolio positions. The complete mechanical appendix that follows is descriptive rather than predictive.

Anthropic

Claude Fable 5.1

anthropic-claude-fable-5-1

2 holdings S&P 500 (SPY)
Biotechnology (XBI) 35% S&P 500 (SPY) 65%
Confidence
0.57
Run Type
official
Rationale

Only biotech combines a strong prior relative trend, a moderate quiet pullback, high quality score and low SPY correlation, giving a modest edge as a reversal candidate. Small-cap and small-value pullbacks look quality-driven but the 5% 10-year yield and weak breadth remove conviction, so they are labeled no_edge. Crowded winners (cyber, Taiwan, semis, crypto) lack in-window catalysts and carry high vol; defense, industrials and solar show persistent rather than shocked weakness. With most of the slate near coin-flip, defaulting the bulk of the portfolio to SPY is appropriate.

Narrow market: SPY roughly flat over one month while equal-weight lagged by 3.7 points and only ~32% of assets beat SPY. 10-year yield at 5% and Brent above $100 pressure rate-sensitive, small-cap and cyclical exposures, while mega-cap tech, crypto and oil carried returns. Breadth deterioration and a heavy macro calendar (GDP, JOLTS, ADP, durable goods) argue for a mixed regime with limited high-conviction reversal setups and elevated risk of trend breaks in crowded winners.

Portfolio
  • Biotechnology (XBI): 35% - V3 selected model rank 1: overreaction with 57% estimated probability of beating SPY.
  • S&P 500 (SPY): 65% - Deterministic SPY fallback for V3 slots without an eligible active candidate.
Key Risks
  • 10-year yield sustained above 5% could extend pressure on small caps, biotech financing and duration assets
  • Reversal in concentrated mega-cap tech leadership would hurt SPY while not necessarily helping the selected candidates
  • Oil above $100 and weak manufacturing data (Q3 GDP, durable goods) could trigger a growth scare hitting high-beta candidates
  • Biotech-specific clinical or regulatory headlines add idiosyncratic risk beyond the factor thesis

Rationale

Only the high-quality pullback names combine a strong prior relative trend with a recent relative drawdown that looks flow- and rate-driven rather than fundamental. Biotech ranks first: best combination of prior relative strength, deep recent pullback, and shallow absolute drawdown. Small value and small cap follow as diversified mean-reversion candidates. Crypto and semiconductor strength is real but unsupported by independent in-window catalysts and carries beta risk that would hurt in a rate-driven selloff, so they rank below the benchmark or near it.

Narrow mega-cap leadership with breadth deterioration (RSP -3.7% vs SPY over 21 sessions, only ~32% of assets positive) against a 5.00% 10-year yield and flat industrial production. Rate pressure is the dominant macro constraint, penalizing small caps, rate-sensitive defensives and long-duration equity. Dispersion is high: crypto and commodities far outperformed while defense and solar collapsed. I treat the rate-driven broad pullback in high-quality small caps and biotech as partly an overreaction, but I do not extrapolate crypto or semiconductor strength without independent in-window support.

Portfolio
  • Biotechnology (XBI): 35% - V3 selected model rank 1: overreaction with 58% estimated probability of beating SPY.
  • US Small-Cap Value (IWN): 35% - V3 selected model rank 2: overreaction with 55% estimated probability of beating SPY.
  • S&P 500 (SPY): 30% - Deterministic SPY fallback for V3 slots without an eligible active candidate.
Key Risks
  • A further rise in the 10-year yield above 5% would extend the small-cap and biotech underperformance rather than reverse it.
  • Breadth deterioration could persist, keeping mega-cap-weighted SPY ahead of every equal-weight-like candidate.
  • Biotech's 29% volatility means the 80% excess-return band is wide and the median edge is small.
  • Scheduled GDP, JOLTS and payroll-adjacent releases in late September could trigger a growth scare that hits high-beta pullback names hardest.

Rationale

Selecting sectors that have experienced recent pullbacks but maintain reasonable quality scores, anticipating a reversal in the short term.

The market is showing mixed signals with recent slight declines in major indices except Nasdaq, while industrial production is flat and the 10-year yield is at 5%.

Portfolio
  • Aerospace and Defense (ITA): 35% - V3 selected model rank 1: overreaction with 60% estimated probability of beating SPY.
  • Metals and Mining (XME): 35% - V3 selected model rank 2: overreaction with 58% estimated probability of beating SPY.
  • Industrials Sector (XLI): 30% - V3 selected model rank 3: overreaction with 56% estimated probability of beating SPY.
Key Risks
  • Interest rates remaining high could pressure equities.
  • Industrial production stagnation could signal broader economic weakness.

Rationale

Biotech narrowly clears the eligibility threshold as a relative pullback following strong prior performance, without supplied sector-specific deterioration. Small-value and small-cap reversals are plausible but insufficiently convincing at prevailing yields. Only biotech qualifies under the fixed rule; unused slots remain in SPY. Quality scores are price-derived evidence, not proof of business quality.

Cross-sectional return spreads are wide despite a nearly flat SPY, although the aggregate dispersion statistic is missing. Weak breadth, a 5.00% Treasury yield, expensive oil and declining manufacturing constrain broad reversal bets. Biotech offers a tentative relative-overreaction opportunity; other quality pullbacks face meaningful financing and growth headwinds. Recent technology and crypto leadership lacks independent fundamental confirmation in the briefing.

Portfolio
  • Biotechnology (XBI): 35% - V3 selected model rank 1: overreaction with 55% estimated probability of beating SPY.
  • S&P 500 (SPY): 65% - Deterministic SPY fallback for V3 slots without an eligible active candidate.
Key Risks
  • Treasury yields could rise further, extending financing pressure on biotech and smaller companies.
  • Elevated oil prices and weak manufacturing could produce further cyclical deterioration rather than mean reversion.
  • Late-September labor, spending and growth releases could alter market leadership before the exit close.
  • No biotech-specific catalyst is supplied, so its relative pullback may persist beyond the one-month window.
  • The entry close follows the frozen snapshot; intervening price changes could absorb the estimated reversal opportunity.

Portfolio S&P 500 (SPY)
S&P 500 (SPY) 100%
Confidence
0.50
Run Type
official
Rationale

Only two candidates meet overreaction plus 55% p_beat threshold; remaining slate shows insufficient edge for allocation.

Broad equity weakness with isolated strength in cybersecurity and crypto; macro data stable but no clear continuation catalyst across slate.

Portfolio
  • S&P 500 (SPY): 100% - Deterministic SPY fallback for V3 slots without an eligible active candidate.
Key Risks
  • Macro data revisions could pressure equities
  • Crypto volatility exceeds slate norms
  • Low dispersion limits relative outperformance

Run Type

Rationale

Highest conviction on quality-pullback small-cap and biotech names showing overreaction after solid prior trends with contained drawdowns; remaining slate either lacks sufficient p_beat edge, carries excessive vol, or reflects supported short-term strength unlikely to sustain excess over SPY for the full month, so benchmark preference dominates unused slots.

SPY near flat with low positive-asset share, 10y at 5%, industrial production unchanged, and equal-weight lagging; short-term crypto/tech strength contrasts with pullbacks in small-caps, industrials, defense and biotech, favoring selective mean-reversion over pure momentum continuation into the one-month window.

Portfolio
  • US Small-Cap Stocks (IWM): 35% - V3 selected model rank 1: overreaction with 58% estimated probability of beating SPY.
  • Biotechnology (XBI): 35% - V3 selected model rank 2: overreaction with 57% estimated probability of beating SPY.
  • US Small-Cap Value (IWN): 30% - V3 selected model rank 3: overreaction with 56% estimated probability of beating SPY.
Key Risks
  • 10-year yield holding at or above 5% could extend pressure on equities and duration-sensitive names
  • Low positive-asset share and RSP underperformance signal fragile breadth that may reverse quality-pullback thesis
  • High-vol crypto and semiconductor beta could spill over into risk-off if momentum fades
  • Upcoming labor, claims, and sentiment data (Sept 24-30) may shift growth expectations abruptly

Rationale

Cross-section is mixed with mega-cap SPY resilience versus broad lagging stocks and 5% long rates. Highest-quality pullbacks are biotech and small caps; only biotech combines a labeled overreaction with a modest >50% chance of beating SPY over one month. Continuation names are already extended or high-vol, and solar looks like deterioration rather than a clean bounce.

SPY is near a 52-week high with a roughly flat week while equal-weight and most assets lagged, 10-year yields are at 5%, industrial production is unchanged, and leadership is concentrated in a few high-beta growth and crypto names versus cyclicals that sold off. One-month edge versus SPY is limited and mixed rather than a clean continuation or reversal regime.

Portfolio
  • Biotechnology (XBI): 35% - V3 selected model rank 1: overreaction with 56% estimated probability of beating SPY.
  • S&P 500 (SPY): 65% - Deterministic SPY fallback for V3 slots without an eligible active candidate.
Key Risks
  • 10-year yield at 5% can keep duration-sensitive and small-cap multiples under pressure into October data.
  • Scheduled labor, GDP, and sentiment releases from September 24–30 can reverse any mean-reversion in cyclicals.
  • High-beta semiconductors, Taiwan, crypto, and solar can dominate one-month dispersion if risk appetite flips.
