Reading a crypto ETF: the vocabulary in plain words
What tracking difference, spot, sponsor and staking mean on a crypto ETF, why these are trusts rather than registered funds, and why two returns cannot always be subtracted.
Two returns can be subtracted while both are small, and what comes out is the gap between them. Once they have grown far enough apart it stops being that. A trust that returned +622.7% against a coin that returned +1,840.8% is 1,227 points behind, which is correct arithmetic and tells a holder who has seven times their money nothing true. Where that has happened ETFIQ prints the ratio of the two growth factors instead, as a share of the coin’s own growth, and labels it as one rather than as points. 14 of the 55 funds on this desk are in that state today, so both forms appear in the same column and each says which it is.
- Tracking difference
- The fund’s total return minus the coin’s over exactly the same days, in percentage points. The fee, the custody cost, the creation and redemption friction and whatever the market paid for the shares, all of it, in one number.
- Spot
- The fund holds the coin itself, through a custodian, rather than futures on it or shares in companies that own it. Only spot funds are on this desk; the others are measured where they belong.
- Sponsor
- Who runs the trust. A spot crypto ETF is a 1933 Act trust rather than a registered investment company, so it has a sponsor rather than an adviser, and files a 10-K rather than an N-PORT.
- Thinly quoted
- A fund whose price sat unchanged on more than one trading day in twenty. Its quoted return is what somebody paid on the days anyone traded, which is not the same thing as what the fund did, so ETFIQ shows it and does not rank it against funds that trade.
- Staking
- Only proof of stake coins can be staked, so it exists for ether and Solana funds and cannot exist for a bitcoin one. Where a fund stakes, the yield and the sponsor’s share of it are terms in its own filings.
