Diversifying Trading Portfolios Across Correlations, Strategies, Timeframes, and Venues
Summary
The article presents correlation as a guide to building a diversified trading portfolio. For trend following, it recommends combining instruments with lower correlations so positions do not behave like a single exposure. For pairs trading, it suggests seeking highly related instruments whose spread may be suitable for hedging or mean reversion, while noting that correlation alone does not establish cointegration.
It extends diversification across strategy types, such as trend and reversal, across trading timeframes, and across exchanges. The author argues that mixing these sources of return may smooth aggregate performance and help manage drawdowns. The examples are conceptual; the document supplies no data, tests, or portfolio construction rules to substantiate the claimed improvement. It also notes that smaller venues may have more apparent arbitrage opportunities but can carry liquidity, operational, and counterparty risks, using past exchange failures as cautionary examples. Diversification can reduce concentration, but it does not guarantee stable returns or remove shared market risks.
Key ideas
- Low-correlated instruments can broaden exposure in trend-following portfolios.
- Pairs trading typically seeks related instruments, but correlation alone does not prove a stable spread relationship.
- Mixing strategy types and timeframes may reduce concentration in a single market regime.
- Exchange diversification has to account for liquidity, operational, and counterparty risks.
- The article offers qualitative guidance without empirical evidence or a formal allocation method.
