category	finance
description	Investment management skill — portfolio construction, analysis, and execution. Compounds finance-substrate (accounting/tax) + wealth-management (projections/goals) into a full financial framework. Covers traditional investing (stocks, ETFs, bonds), alternatives (crypto, prediction markets, real estate, VC), quantitative analytics (factor models, Monte Carlo, optimization), and platform integration (Alpaca, Coinbase, Polymarket, agent-browser for Colombian platforms). Embodies philosophies from Buffett, Dalio, Bogle, Munger, and Marks. Use when: (1) building or analyzing a portfolio, (2) screening stocks/ETFs/crypto, (3) running backtests or factor analysis, (4) executing trades or rebalancing, (5) tracking investments across platforms, (6) researching market data or fundamentals, (7) making investment decisions with structured frameworks. Triggers on 'investment', 'portfolio', 'stocks', 'ETF', 'bonds', 'crypto', 'trading', 'backtest', 'factor model', 'rebalance', 'Polymarket', 'Alpaca', 'asset allocation'.

Investment Philosophies (Built-in Frameworks)

The skill embeds decision frameworks from legendary investors. Each philosophy is a scoring lens that can be applied to any investment.

Value (Buffett/Graham/Munger)

Principle	Implementation
Economic moat analysis	Score competitive advantage: brand, network, switching cost, scale
Margin of safety	Require 25%+ discount to intrinsic value (DCF, owner earnings)
Circle of competence	Flag unfamiliar sectors; require deeper research threshold
Owner earnings	Net income + depreciation - capex (not GAAP earnings)
Quality over price	ROIC > WACC, consistent ROE > 15%, low debt/equity

Systematic (Dalio/AQR)

Principle	Implementation
All-Weather allocation	Risk-parity: equal risk contribution from growth, inflation, deflation
Factor exposure	Decompose returns into market, value, momentum, quality, size
Risk parity	Weight by inverse volatility, target equal risk contribution
Regime awareness	Detect growth/inflation quadrant, adjust allocation
Correlation regime	Monitor rolling correlations; diversification fails in crises

Passive/Index (Bogle)

Principle	Implementation
Three-fund portfolio	Total market + international + bonds; rebalance annually
Minimize costs	Flag any fund with expense ratio > 0.20%
Tax efficiency	Index funds in taxable, bonds in tax-deferred
Stay the course	Reject market timing; dollar-cost average
Simple beats complex	Baseline comparison for every active strategy

Second-Level Thinking (Marks)

Principle	Implementation
Consensus vs reality	Flag positions where market consensus is priced in
Risk is not volatility	Focus on permanent capital loss, not price fluctuation
Market cycles	Track Shiller CAPE, yield spreads, sentiment indicators
Asymmetric outcomes	Seek situations where upside >> downside
Know what you don't know	Confidence-weighted recommendations

Barbell (Taleb)

Principle	Implementation
85% ultra-safe + 15% high-convexity	Split portfolio into safe (CDTs, treasuries) + optionality (crypto, VC, prediction markets)
Antifragile positions	Identify investments that benefit from volatility
Avoid the middle	Skip mediocre risk-return profiles
Small bets, big payoffs	Position size by max loss tolerance, not expected return

Skill Modes

1. screen — Security Screening

Search and filter stocks, ETFs, crypto, and other securities by criteria.

Script: scripts/screener.py

Screening criteria:

• Fundamental: P/E, P/B, EV/EBITDA, FCF yield, ROIC, ROE, debt/equity, dividend yield
• Technical: RSI, MACD signal, price vs 200-day MA, 52-week range position
• Quality: earnings consistency, revenue growth, margin stability
• Momentum: 1/3/6/12-month returns, relative strength
• Value composite: Piotroski F-Score, Greenblatt Magic Formula rank
• Size: market cap filters

Data sources: yfinance, Financial Modeling Prep, OpenBB

Autonomous decision plane — services/tradingview-bridge

A self-contained, paper-only, human-gated trading control system: a webhook receiver + multi-broker executor, plus a closed self-improving loop — research (walk-forward + anti-overfit scoring), optimize (EGRI param search with a true train/test holdout), and roster (human-gated promotion of optimized params into the roster the orchestrator measures). Drives TradingView's Paper simulator via the Interceptor CLI (no inbound API), or runs the entire decision loop on synthetic/CSV bars with no browser or broker. It measures and recommends — it never moves live capital on its own.

Compound: Autoany Integration (EGRI)

This skill is EGRI-aware. When a user's request implies iterative optimization or strategy search, the agent should scaffold a problem-spec from the templates below and delegate to /autoany for autonomous improvement.

Optimization Triggers

Invoke /autoany when the user asks to:

• "Optimize" — allocation, weights, strategy parameters
• "Find the best" — strategy, allocation, screening criteria
• "Compare strategies" — systematic comparison across N variants
• "Backtest variations" — test parameter sweeps
• "What if I changed" — sensitivity analysis via mutations
• "Stress test" — combined with optimization intent

EGRI Problem-Spec Templates

Template	Artifact	Evaluator	Score	Use When
strategy-optimization	strategy.yaml (weights, rules)	backtest.py --egri	Sharpe ratio	Optimizing portfolio allocation
screen-evolution (planned)	screen_criteria.yaml (thresholds)	screener.py + eval_screen.py (eval_screen.py not yet shipped)	Forward return	Evolving stock selection criteria

The strategy-optimization loop is live (backtest.py --egri ships). The screen-evolution loop is planned — its eval_screen.py evaluator is not yet implemented. Templates are at templates/egri/. The strategy artifact schema is at templates/egri/strategy-artifact.yaml.

Delegation Flow

1. User request → agent detects optimization intent
2. Load personal context from finance-substrate (patrimonio, salary, TRM)
3. Pull historical market data (market_data.py)
4. Scaffold problem-spec from template, fill in:
   - Starting allocation as baseline artifact
   - Period, constraints from policy.yaml
   - Goal metrics from user's request
5. Invoke /autoany with scaffolded problem-spec
6. EGRI loop runs: Proposer → Executor (backtest.py) → Evaluator → Selector
7. Return promoted strategy + ledger summary to user
8. Log results for cross-session strategy inheritance (autoany-lago)

EGRI Evaluator Bridge

scripts/eval_backtest.py wraps backtest.py for use as an EGRI evaluator:

• Takes a strategy YAML artifact + period
• Returns structured Outcome (score, constraints_passed, violations)
• Applies constraint expressions from the problem-spec
• Can be used standalone: python3 eval_backtest.py --strategy-file strategy.yaml --period 10y

Safety Constraints (enforced in EGRI loops)

• EGRI loops over historical data are autonomous (sandbox mode)
• EGRI loops that propose live trades require human gate (HumanGate selector)
• Max drawdown constraint: -15% (from policy S6)
• Position concentration: <= 25% (from policy S2)
• Budget: 50 trials max, 1 hour total
• All trials logged to ledger for audit and cross-run inheritance

Dependencies

• Python 3.10+
• finance-substrate skill (accounting, tax, certificates)
• wealth-management skill (projections, goals, portfolio summary)
• autoany (optional, for EGRI optimization loops)
• Market data: yfinance, fredapi, pycoingecko (free)
• Optimization: pypfopt, riskfolio-lib, cvxpy (optional, for advanced modes)
• Trading: alpaca-trade-api, coinbase-advanced-py (optional, for execution)
• Technical: pandas-ta, arch (optional, for quantitative modes)
• No paid services required. All data stays local.
