SEC approves listing rules for proposed 3x bitcoin and ether funds that seek triple returns only one day at a time

Each session's gain or loss becomes the next session's starting balance ^[3]. After a down day the fund has less capital, so it cuts exposure to get back to three times. The rebound then lands on a smaller position ^[5].

Forkast's two-day example puts a number on that resizing. Bitcoin rises 10% and then falls 10%, a net loss of 1%, while the 3x fund gains about 30%, loses about 30% and ends near minus 9% ^[17]. Forkast calls that 8 percentage points worse than holding three times the underlying ^[17]. Three times the 1% loss is minus 3%, so the reset on its own cost 6 points in two sessions. Forkast's 8 is the distance from the unleveraged 1% loss ^[20].

Over a longer stretch the gap can be much larger. An SEC investor bulletin describes a real four-month period in which an unnamed index gained about 8% while a fund seeking three times its daily return lost 53% ^[18]. A buyer expecting triple the index would have pencilled in a 24% gain, so the miss on a correct call about direction was 77 points ^[21]. CryptoSlate noted that the example was not a bitcoin fund or a forecast for these products ^[18]. It comes from the same agency that approved the listing rules ^[1].

The filing fixes the running costs. VS Trust's Oct. 7 amended filing lists a 1.85% annual management fee for both funds and estimates breakeven returns of 1.98% for bitcoin and 2.78% for ether, counting other expenses and assumed interest on collateral ^[9]. The fee is the same for both, so the other costs net of that interest come to 0.93 points a year for ether against 0.13 for bitcoin ^[19]. The filing, as reported, does not explain the 0.80-point difference. Futures rolls add to the bill: CME contracts typically trade above spot, according to Forkast, and rolling them produces contango losses over time ^[11].

Holding could still work out better than this. A sustained advance can let a daily-reset fund earn more than three times the benchmark's cumulative gain ^[6]. The roll can also work in the fund's favour, depending on how nearer and later contracts are priced against each other, CryptoSlate wrote ^[12]. Fee waivers could pull the bill toward the 0.33% low end of the range Forkast cites from the S-1 breakeven tables ^[10].

We think BITH and ETHK belong with traders who open and close a position around a view on the next few sessions, and the SEC's 53% case is the evidence for that ^[18]. Forkast reached the same view, writing that the product "is designed for short-term traders who actively manage positions, not for holders" ^[14]. A long, steady bitcoin rally in which holders beat three times the cumulative move would prove us wrong. Getting there means calling bitcoin's path as well as where it ends up ^[6].
