ETFs

Gold funds, inverse and leveraged funds, and the mechanics that decide whether a fund does what its name says over the period you hold it.

An ETF name tells you the target; the prospectus tells you the method. A gold fund might hold bars in a vault or shares in mining companies. An inverse fund aims for the opposite of one day's index return, which is a different thing from the opposite of a month's. The lists set the main funds side by side, and the strategies explain what each design means for a trade.

The leveraged ETF decay calculator shows how a daily-reset fund drifts from its multiple over a run of up and down days.

Definitions

  • ETF premium and discount

    The difference between an ETF's market price and its net asset value per share, shown as a percentage: a premium when the price is higher, a discount when it is lower.

  • Tracking error

    The variability of the gap between a fund's return and its index's return over time, usually measured as the standard deviation of that gap.

  • Volatility decay

    The drag on a daily-reset leveraged or inverse fund when its index moves up and down, because each day's percentage move is applied to a new base.
