This is particularly useful for interest rate modelling in

  • How to Improve Commodity Momentum Using Intra-Market Correlation [Quantpedia]

    Momentum is one of the most researched market anomalies, well-known and widely accepted in both public and academic sectors.

  • Exploring Bond Tax Efficiency: Futures or Bond ETFs? [Alpha Architect]

    Bond futures are often assumed to be more tax-efficient than bond ETFs. My analysis indicates that this assumption is frequently incorrect. Although investors might view the 60/40 tax treatment of futures as advantageous, a futures strategy faces several challenges compared to a bond ETF, including frequent taxable events, potential tax drag from cash collateral, and additional state taxation. My
  • Adding Leveraged, Long-Short Factor Strategies to Improve Tax Alpha [Alpha Architect]

    Empirical research, including the 2020 study An Empirical Evaluation of Tax-Loss Harvesting Alpha and the 2023 study Expected Loss Harvest from Tax-Loss Harvesting with Direct Indexing, has found that tax-loss harvesting strategies in separately managed accounts (SMAs) can improve the post-tax returns of an investment portfolio by employing a strategy of selling positions in securities

    Semivolatility-managed portfolios Daniel Batista da Silva (U. of Geneva) and M. Fernandes (Getulio Vargas Fnd.) July 2024 There is ample evidence that volatility management helps improve the risk-adjusted performance of momentum portfolios.

  • Book Reviews and Reading List [Mark Best]

    How do you eat an elephant? I have wanted to write a reading list but I have been apprehensive since I didnt want to include too much and wanted also to explain why the books were in the list. If you want to trade crypto there is no point reading the Hull interest rate model book. This list likely will be a work in progress so keep that in mind. As I write this I realise I have a deep problem

  • Closing the loop [OSM]

    Summer has a way of getting away from you. That is as much relevant for blog writing as it is for life. Nonetheless, before summer ends we wanted to dust off our series on regime prediction and close the loop on the remaining techniques we had yet to investigate.

  • Overnight Reversal Effects in the High-Yield Market [Quantpedia]

    High-yield bond ETFs represent a unique financial vehicle: they are highly liquid instruments that hold inherently illiquid securities, creating a fertile ground for predictable market behaviors.
