Intraday NAV Swaps for Confidential ETF Arbitrage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Active ETFs face a challenge in maintaining confidentiality of their portfolio trading information while enabling arbitrage between market trading prices and underlying real-time portfolio values, as full portfolio disclosure is not always necessary for efficient secondary market trading.
Innovation Solution
A system and method that includes a Fund Module, Portfolio Module, Basket Module, Current Valuation Module, Swap Module, and Creation/Redemption Module to track and manage ETF shares, calculate intraday net asset values, and establish NAV Swaps, allowing for arbitrage without full portfolio disclosure, using Creation and Redemption Baskets and Beta Patch Portfolios to maintain confidentiality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If full portfolio disclosure is provided to enable arbitrage, then market efficiency is improved, but confidentiality of trading information is lost
Solution Approach 1:
The patent segments the portfolio information into two distinct components: the Fund Basket (containing a subset of assets) and the Beta Patch Portfolio (containing the remaining assets). This segmentation allows the system to provide sufficient information for arbitrage while protecting confidential trading information. The Fund Basket is disclosed to enable market participants to replicate portions of the portfolio, while the Beta Patch Portfolio maintains confidentiality to prevent front-running of specific trades.
Solution Approach 2:
The patent applies local quality by providing different levels of information disclosure to different market participants based on their needs. The Fund Basket information is made publicly available to enable general arbitrage, while the complete portfolio information remains confidential to protect specific trading strategies. This localized information quality allows the system to balance market efficiency with information protection.
2Object-affected harmful factors
If portfolio confidentiality is maintained to prevent front-running, then trading security is improved, but arbitrage efficiency deteriorates
Solution Approach 1:
The patent segments the portfolio into a disclosed Fund Basket and a confidential Beta Patch Portfolio. This segmentation enables arbitrageurs to efficiently trade based on the disclosed Fund Basket information while the confidential Beta Patch Portfolio continues to protect against front-running of specific trades. The segmented approach maintains arbitrage efficiency without compromising trading security.
Solution Approach 2:
The patent introduces the Fund Basket as an intermediary representation of the portfolio that enables arbitrage without revealing the complete portfolio composition. The Fund Basket acts as a mediator that provides sufficient information for efficient trading while the confidential Beta Patch Portfolio maintains protection against front-running. This intermediary approach resolves the contradiction between transparency and security.
3Productivity
If intraday NAV calculations are performed frequently to support arbitrage, then market liquidity is improved, but computational resources are consumed
Solution Approach 1:
The patent implements periodic intraday NAV calculations at predetermined intervals throughout the trading day, rather than continuous calculations. This periodic approach provides updated NAV values sufficient to support arbitrage and maintain market liquidity, while significantly reducing the computational resources required compared to continuous calculations. The system balances liquidity provision with resource conservation through this periodic update mechanism.

AI summary
A system and method is provided for administering an actively managed fund having shares tradable on an exchange, to support efficient secondary market trading. A Fund Module defines an actively managed ETF. A Portfolio Module tracks a portfolio held by the ETF while maintaining confidentiality of at least a portion thereof. A Basket Module publishes Creation and Redemption Baskets including a subset of the fund portfolio. A Current Valuation Module calculates a current Intraday NAV for the portfolio and Baskets throughout a trading day. A Swap Module provides for periodic entry and exit from NAV Swaps between an ETF Party and Swap Counterparties, who exchange payments based on performance of the fund portfolio and the Fund Basket. A Creation/Redemption Module permits creations and redemptions of ETF shares in exchange for the Fund Basket. Arbitrage is permitted between ETF share price and Intraday NAV without full portfolio disclosure.
