Intraday Portfolio Factor Attribution
Identifying which factors, sector, geography, style, or idiosyncratic, are driving intraday P&L is essential for active managers who need to understand whether their positions are performing as intended. 3forge connects to factor model providers and updates attribution continuously as markets move throughout the session.
The Challenge
End-of-Day Attribution Arrives Too Late to Inform Intraday Decisions
By the time overnight attribution runs, intraday factor drift has already affected positions, and managers cannot act on yesterday's attribution to correct today's exposures.
Attribution only available after close
Most attribution systems run overnight on final closing positions, leaving intraday factor movements invisible until the following morning's report.
Factor model computational demand
Running multi-factor attribution across a large portfolio requires significant computational infrastructure that most risk platforms do not provide on an intraday basis.
Data integration complexity
Factor model outputs, position data, and market data must come together from different systems, and connecting them in real time requires engineering effort most firms have not made.
Unexplained P&L
When realized P&L diverges from factor model expectations, identifying the source requires rapid investigation, as static overnight reports do not support intraday root cause analysis.
The 3forge Approach
Continuous Multi-Factor Attribution on the Live Portfolio
3forge connects to factor model providers, position systems, and market data feeds to compute P&L attribution continuously throughout the trading day. Managers see which factors are contributing at every point in the session, not just at close.
Key Capabilities
What You Can Build with 3forge
Continuous Attribution
Update factor attribution continuously as positions and market prices change, not just overnight after the session closes.
Multi-Factor Model Support
Connect to any factor model provider, Barra, Axioma, or custom, through 3forge's open data adapters with no vendor lock-in.
P&L Decomposition
Break down intraday P&L by factor contribution, security selection, and unexplained residual in real time across the full portfolio.
Drill-Down Navigation
Navigate from total portfolio attribution to strategy, sector, and individual position level instantly to find the source of attribution drift.
Expectation vs. Reality
Compare realized intraday P&L against factor model predictions to identify and investigate divergences as they develop, not after the session ends.
Scenario Attribution
Project how factor attribution would shift under different market scenarios applied to the current live portfolio for real-time hedging analysis.
