SKDD among the 73 inverse ETFs at 2x, over three months
A percentile among the 508 leveraged ETFs at 2x, over three months. SKDD is a percentile among the 73 inverse ETFs at 2x, over three months, a different set, so the two marks are not on one scale. Three months only, against the fund's own daily multiple; a different quarter can rank it very differently. All leveraged ETFs ranked by it →

About SK
Read the multiple against the whole window instead and 2 times SKHY's −13.3% implies −26.6%, which makes SK look 11.3 points short. That is not the fund's objective, which is daily. Of that 11.3, daily compounding is −8.7 points, which any 2 times fund would show over the same path, and the fund itself is −2.6 points against 2 times each day's move, compounded. SK aims to return +2 times SKHY's move each day, then resets. Over one day it does that. Over longer periods the daily results compound, so the total is not +2 times the period's move: it is lower after a fall and recovery, and can be higher in a steady run. SKHY moved at 78% annualized over that window. The more it moves, the further the two figures separate.
Over the three months to Oct 21, 2026, SK lost 37.9%, against −35.3% for twice SKHY's daily moves.
About SKDD
Read the multiple against the whole window instead and −2 times SKHY's −13.3% implies +26.6%, which makes SKDD look 44.6 points short. Of that 44.6, daily compounding is −44.1 points, which any −2 times fund would show over the same path, and the fund itself is −0.5 points against −2 times each day's move, compounded. SKDD aims to return -2 times SKHY's move each day, then resets. Over longer periods the daily results compound, so the total is not -2 times the period's move: it is lower after a fall and recovery, and can be higher in a steady run.
Over the three months to Oct 21, 2026, SKDD lost 18.0%, against −17.5% for twice the inverse of SKHY's daily moves.
Questions people ask
- Which came closer to its daily multiple, SK or SKDD?
- Over the window to Oct 21, 2026, SK finished 11.3 points from what its multiple implies and SKDD finished 44.6 points from its own, so SK came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.
- Are SK and SKDD levered on the same thing?
- Yes. Both are levered on SK hynix, SK at +2 times and SKDD at -2 times the daily move.
- Which one decays faster, SK or SKDD?
- Decay follows how much the underlying moves about. Over this window SK’s moved at 78% annualized and SKDD’s at 78%, so SK has the rougher ride and, at the same multiple, loses more to compounding.
- Can I hold SK or SKDD for a year?
- Both reset every day, so the multiple in the name applies to a single day, and daily results compound. Over a year the total is not the multiple times the year’s move; after a fall and recovery it is lower.
