The goal of the Dirac Portfolio is to see if we might be able to beat the performance of the broad S&P 500 Index (as represented by the SPY ETF) by actively rotating between the sectors that make up that index. I started to build this portfolio last week with the objective of trying to […]
Dirac 2026: 5 January 2026
I have reset the Dirac Portfolio to an $80,000 account and made a minor adjustment to the asset list (“quiver”) in order to limit the number of assets in the quiver to a maximum of 10 for ease of management. I have also decided to move this portfolio to the new algorithm that I have […]
Dirac Portfolio Review: 29 August 2025

Risk management will be a little tougher because of trading restrictions resulting from the fact that these securities are held […]
Dirac Portfolio Review: 3 July 2025
Over the past 18 months I have not had the time to decide how to manage the money that has been sitting in the Dirac Portfolio. This was to be a re-build portfolio project based on using an “Income” model, similar to the Hawking Portfolio, but designed to adopt a mean reversion rather than momentum […]
Dirac Portfolio Review: 8 January 2025
I have sadly neglected the Dirac Portfolio after taking money out of the account for other purposes with the intention of rebuilding once the money was returned to the account. My intention was to invest in beaten down Funds (based on Z-Score calculations) but this plan was somewhat thwarted by the stong bull market through […]
