Contrast the vehicles through which an investor can gain index-based equity exposure

Index exposure can be obtained three main ways. Pooled vehicles such as index mutual funds and ETFs give diversified exposure at low cost; ETFs trade intraday and their in-kind creation and redemption can make them tax-efficient (notably in the US), while mutual funds deal once a day at net asset value. Derivatives-based approaches use index futures, total return swaps or options: they are capital-efficient and quick to put in place, but futures must be rolled, carry basis risk and margin calls, and swaps add counterparty risk. Separately managed accounts hold the shares directly, allowing customisation such as tax-loss harvesting or ESG exclusions, but they need scale and add custody and administration cost. Size, horizon, customisation and tax drive the choice.
