Beta — Beta Coefficient & Systematic Risk Reference

Quick-reference skill for understanding and applying the beta coefficient in finance, portfolio management, and risk analysis.

When to Use

  • Calculating a stock's beta relative to a benchmark index
  • Understanding systematic vs unsystematic risk
  • Applying CAPM to estimate expected returns
  • Constructing beta-neutral or target-beta portfolios
  • Interpreting regression output for asset sensitivity

Commands

intro

scripts/script.sh intro

Overview of beta — definition, intuition, and role in modern finance.

capm

scripts/script.sh capm

Capital Asset Pricing Model — formula, assumptions, and expected return calculation.

calculate

scripts/script.sh calculate

How to calculate beta — regression method, covariance/variance method, and practical steps.

interpret

scripts/script.sh interpret

Interpreting beta values — what β>1, β=1, β\x3C1, and β\x3C0 mean in practice.

types

scripts/script.sh types

Types of beta — levered vs unlevered, adjusted beta, fundamental beta, bottom-up beta.

portfolio

scripts/script.sh portfolio

Portfolio beta — weighted average calculation, target beta, beta hedging strategies.

pitfalls

scripts/script.sh pitfalls

Common pitfalls — estimation window, benchmark choice, non-stationarity, and survivorship bias.

examples

scripts/script.sh examples

Worked examples with real-world beta scenarios and calculations.

安全使用建议
This skill appears coherent and low-risk: it runs a local shell script that prints finance reference material, requests no secrets, and has no installer or network activity. Before installing or running it, (1) verify the scripts/script.sh file is complete and unmodified (the manifest you provided shows a truncated tail), (2) inspect the script to confirm it contains only harmless output (no curl, wget, exec of user-provided input, file deletions, or secret access), and (3) run it in a restricted environment if you are cautious. If you expect the skill to persist data in BETA_DIR, note that the current script does not use that variable — confirm intended behavior with the author.
功能分析
Type: OpenClaw Skill Name: beta Version: 1.0.0 The 'beta' skill bundle is a purely informational reference tool for financial concepts like the Beta coefficient and CAPM. The primary script (scripts/script.sh) contains only static text output (heredocs) and lacks any network activity, file system modifications, or sensitive data access.
能力评估
✓ Purpose & Capability
The name and description (beta/CAPM/reference) align with the included functionality. The skill only provides explanatory commands (intro, capm, calculate, etc.) implemented in a bundled scripts/script.sh. One minor inconsistency: SKILL.md documents a BETA_DIR configuration variable, but the bundled script does not appear to read or use any environment variables.
✓ Instruction Scope
Runtime instructions tell the agent to run the local scripts/script.sh with fixed subcommands. The script content is static text emitted via heredocs (no network calls, no reading of arbitrary system files, no credential access). There is a small manifest anomaly: the provided scripts/script.sh content in the listing appears truncated at the end — you should verify the file is complete before executing, but the visible content shows only read-only documentation output.
✓ Install Mechanism
No install spec is present (instruction-only plus a local script). Nothing is downloaded or written to disk by an installer step; risk from installation is minimal.
✓ Credentials
The skill declares no required environment variables, credentials, or config paths. The SKILL.md documents an optional BETA_DIR setting (default ~/.beta/) but the script does not use environment variables — the requested privilege level is proportionate to the purpose.
✓ Persistence & Privilege
always is false and model invocation is normal/default. The skill does not request persistent system presence or modify other skills or agent-wide settings.
