SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It helps you stop relying on “past-best performance” by systematically evaluating mutual funds using performance, risk-adjusted metrics, style-box regression, and style-drift detection, then guiding FOF (fund-of-funds) construction and ETF selection.

Core Features & Use Cases

  • Multi-metric fund screening: Compare annualized returns, Alpha vs benchmark, information ratio, Sharpe/Sortino/Treynor, drawdown, volatility, and Calmar to rank funds against clear quality thresholds.
  • Sharpe style-box regression & validation: Determine whether a fund’s realized exposure matches its declared style using a nine-grid value/balance/growth and size mapping, including R²-based clarity.
  • Style drift detection: Use rolling-window regression to flag significant style shifts (|Δβ| thresholds, R² trends) so you can detect closet-to-index behavior or manager-driven style changes.
  • FOF portfolio construction: Build diversified allocations across asset classes and select complementary style exposures, then apply a rebalancing rule based on deviation thresholds.
  • ETF selection framework: Evaluate ETFs via tracking error, fee structure, liquidity, and size to choose efficient and tradable passive/strategy vehicles.

Quick Start

Use the mutual-fund-analysis skill to generate a fund screening report that includes performance ranking, style-box regression results with R², drift assessment over rolling windows, and a recommended FOF allocation plan.

FAQPage Schema
How do I screen mutual funds using risk-adjusted returns instead of past performance?

Mutual fund screening evaluates annualized returns, Alpha, Sharpe, Sortino, Treynor, drawdown, and Calmar ratios to rank funds against quality thresholds, preventing reliance on past-best performance. It systematically compares funds using documented metric thresholds and benchmark assumptions.

What is Sharpe style-box regression and how does it validate fund exposure?

Sharpe style-box regression determines whether a fund’s realized exposure matches its declared style using a nine-grid value/balance/growth and size mapping. It validates fund exposure by calculating R²-based clarity to ensure the actual portfolio aligns with the stated investment strategy.

How do I detect style drift in a mutual fund over time?

Style drift detection uses rolling-window regression to flag significant style shifts by monitoring |Δβ| thresholds and R² trends. This identifies closet-to-index behavior or manager-driven style changes over specified rolling window parameters, ensuring portfolio style consistency.

Can I use this to build a fund-of-funds allocation with rebalancing rules?

FOF portfolio construction builds diversified allocations across asset classes and selects complementary style exposures. It applies rebalancing rules based on deviation thresholds across market cycles, generating a recommended allocation plan with structured portfolio selection.

How do I evaluate ETFs for tracking error and liquidity?

ETF selection evaluates tracking error, fee structure, liquidity, and size to choose efficient passive or strategy vehicles. The framework assesses ETFs against documented metric thresholds to identify tradable passive products that align with portfolio construction goals.

What metadata format is required to generate a fund screening report?

Fund screening report generation requires YAML-defined metadata containing the fund name and description. This YAML input provides the baseline operational metadata needed to execute performance ranking, style-box regression, and drift assessment.
