Correlation Risk Limiter
Avoid doubling down on the same risk.
Overview
This pillar analyzes the correlation between a potential new market and your existing portfolio. It helps you manage hidden risks by suggesting smaller position sizes for highly related bets, promoting true diversification.
What It Does
It calculates the historical price correlation between a new market you are considering and all the markets currently in your portfolio. Using this data, it determines your 'effective exposure' to underlying real world factors. If the new market is strongly linked to existing positions, the pillar recommends a reduced position size to prevent over-concentration.
Why It Matters
True diversification is more than just betting on different markets; it's about betting on different underlying outcomes. This pillar prevents a single event from wiping out multiple positions at once, preserving your capital and improving risk-adjusted returns.
How It Works
First, the pillar accesses your current portfolio holdings. When you select a new market, it retrieves the historical price data for both the new market and your existing ones. It then computes a correlation coefficient for the new market against each holding, identifying the strongest link. Based on this maximum correlation, it generates a 'Size Reduction Factor' to guide your position sizing.
Methodology
The analysis uses a 90-day rolling Pearson correlation coefficient to measure the linear relationship between market price histories. The final Size Reduction Factor (SRF) is calculated as SRF = 1 - (max_correlation^2), where max_correlation is the highest coefficient found between the new market and any single asset in the portfolio. This ensures the reduction is more pronounced for very high correlations.
Edge & Advantage
This provides a professional-grade risk management edge, protecting your bankroll from systemic risks that most traders overlook until it is too late.
