ETF (Exchange-Traded Fund)
A fund that trades on an exchange like a single share and usually tracks an index, giving low-cost, diversified exposure to a whole market.
An exchange-traded fund (ETF) holds a basket of assets — often the constituents of an index — and its shares trade on an exchange throughout the day, like a stock. Because most ETFs track an index rather than trying to beat it, their running costs are usually low.
For a rules-based approach, ETFs are a convenient way to gain broad, transparent exposure to an asset class. Witan Way reads regimes on reference indices, never on a specific named ETF: the fund is the wrapper an investor might choose, not the signal itself.
