BITX and ETHU: daily 2× returns and compounding
Understand the daily 2× targets of BITX and ETHU, why longer-term returns differ, and how daily resets, compounding and futures exposure affect comparisons.
Where can I compare inverse Bitcoin and Ethereum ETF prices?
BITI, SBIT and BTCZ target daily inverse Bitcoin exposure; SETH and ETHD target daily inverse Ethereum exposure. Compare their reference estimates, daily multipliers and previous regular closes. These funds follow their stated benchmarks; holding-period returns are not a fixed negative multiple of the coin’s return, and an estimate is not an executed ETF trade.
The multiple describes a daily objective
A daily 2× product targets twice its benchmark's return over a specified daily measurement period. Its benchmark, the cryptocurrency itself and the ETF's traded price are not necessarily identical. The label does not promise twice a weekend's or month's return. Consult the product's prospectus for its benchmark and reset period before interpreting a displayed multiple.
100 → 110 → 99 versus 100 → 120 → 96
Consider an example excluding costs. A benchmark rises 10% and then falls 10%, moving from 100 to 110 to 99. A product delivering exactly twice each day's return rises 20% and then falls 20%: 100 to 120 to 96. The two-day returns are −1% and −4%, because the second return applies to a different starting amount.
Recovery requires a different percentage
Moving from 96 back to 100 requires about 4.17%; moving from 99 to 100 requires about 1.01%. A loss and its recovery do not use the same percentage base. This does not mean leveraged products always decline with time. A persistent trend and repeated reversals can produce different compounded outcomes even when their starting values match.
Futures introduce another difference
A futures-based product differs from one holding the coin directly. Replacing expiring contracts, differences between futures and spot prices, and expenses can affect returns. Those effects need not have an identical direction or size each time. Today's coin price alone therefore cannot explain every movement in an ETF, even before considering the daily leverage target.
What to check beside an estimate
Check the daily multiple, positive or inverse exposure, and the reference close's date. A long weekend does not mean the actual ETF reset on every calendar day. Distributions and splits can also affect price comparisons. CoinETF estimates provide an observation aid, rather than a substitute for the product prospectus or the prices available on your broker's order screen.
