The Problem & The Solution

Why Style Analysis Matters — and How to Do It Properly

Style Analysis Without the Right Tool

A manager's stated strategy and their actual return drivers can diverge significantly — style analysis is the only way to verify the difference.

  • Managers claim one strategy but returns may reveal exposure to very different factors — without analysis this risk is completely invisible
  • Style drift — where a manager gradually shifts strategy — increases portfolio risk significantly if left undetected over time
  • Building a genuinely diversified portfolio requires knowing the true factor exposures of each manager, not their self-reported strategy
  • Self-reported style information in DDQs may not match the reality revealed by return data over multiple market cycles
  • Peer group construction requires accurate style classification — which self-reporting alone cannot guarantee objectively

What AlternativeSoft's Style Analysis Reveals

Returns-based style analysis and multi-factor regression that reveal the reality behind every manager's stated strategy.

  • Returns-based style analysis (RBSA) identifying factor loadings and style consistency over time with full statistical diagnostics
  • Multi-factor regression revealing true exposure to equity, credit, rate, commodity and currency factors
  • Rolling window analysis showing how factor exposures have changed month by month — detecting drift early
  • Peer group style comparison: see how a manager's true style profile compares against strategy peers
  • Style analysis feeds directly into portfolio construction for genuinely diversified multi-manager allocations
Style Analysis Capabilities

Understand Every Hedge Fund Manager's True Style

Returns-based and factor analysis for rigorous manager evaluation and portfolio construction.

Returns-Based Style Analysis

Sharpe's RBSA decomposes fund returns against style indices. Identifies which styles best explain each manager's return pattern — objectively, from data.

Factor Regression

Multi-factor regression against equity, credit, rates, commodities and FX factor series with full statistical significance reporting for every loading.

Style Drift Detection

Rolling 12, 24 and 36-month window analysis shows how factor loadings change month by month. Detects strategic drift before performance diverges visibly.

Peer Style Comparison

Compare a manager's true style profile against strategy peers. Identify managers with genuinely differentiated styles that provide real diversification.

Portfolio Style Aggregation

Aggregate individual manager style profiles at portfolio level. Build multi-manager portfolios with low aggregate factor correlation.

Style Analysis Reports

Full style decomposition reports for due diligence files and IC presentations — factor loadings, R-squared and statistical confidence metrics included.

Frequently Asked Questions

Returns-based style analysis (RBSA), developed by William Sharpe, decomposes a fund's historical returns against a set of style indices or factor series to identify which styles best explain the return pattern. For hedge funds, this reveals the true factor exposures driving returns — which often differ significantly from the manager's stated strategy.
AlternativeSoft's factor models include global and regional equity factors, credit spread factors, interest rate duration, currency factors, commodity factors, volatility factors and hedge fund strategy indices. Custom factor series can also be uploaded.
Style drift occurs when a hedge fund manager gradually changes their investment approach without declaring this change to investors. AlternativeSoft's rolling window analysis detects drift early by showing how factor loadings change month by month, enabling investors to raise concerns before performance diverges.
By understanding the true factor exposures of each candidate manager, portfolio constructors can identify pairs with genuinely low factor correlation versus those that share hidden risk factors. This leads to more genuinely diversified multi-manager portfolios.
Returns-based style analysis requires a minimum of 24–36 months of return data for statistical reliability, with more history providing more reliable factor loadings. AlternativeSoft shows R-squared and t-statistics for all factor coefficients.
