ASTN in plain words
Three months to Sep 11, 2026: ASTN returned −19.4% where its own daily promise gave −10.8%, 8.6 points short. Read the multiple against the whole window instead and −2 times ASTS's −27.4% implies +54.7%, which makes ASTN look 74.2 points short. 65.5 of that is daily compounding, which happens to any −2 times fund over the same path, and the rest is the fund. ASTN aims to return -2 times ASTS's move each day, then resets. Over one day it does that. Over longer, the daily results compound, so the total is not -2 times the period's move: in a market that falls and comes back it is reliably less, and in a steady run it can be more. ASTS moved at 98% annualized over that window. That is what decides how far the two figures separate: the same fund on a calm underlying and a violent one is a different product.
ASTY in plain words
Three months to Sep 11, 2026: ASTY returned −62.0% where its own daily promise gave −58.4%, 3.6 points short. Read the multiple against the whole window instead and +2 times ASTS's −27.4% implies −54.7%, which makes ASTY look 7.2 points short. 3.7 of that is daily compounding, which happens to any +2 times fund over the same path, and the rest is the fund. ASTY aims to return +2 times ASTS's move each day, then resets. Over longer, the daily results compound, so the total is not +2 times the period's move: in a market that falls and comes back it is reliably less, and in a steady run it can be more.
Questions people ask
- Which came closer to its stated multiple, ASTN or ASTY?
- Over the window to Sep 11, 2026, ASTN finished 74.2 points from what its multiple implies and ASTY finished 7.2 points from its own, so ASTY came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.
- Are ASTN and ASTY levered on the same thing?
- Yes. Both are levered on ASTS, ASTN at -2 times and ASTY at +2 times the daily move.
- Which one decays faster, ASTN or ASTY?
- Decay follows how much the underlying moves about. Over this window ASTN’s moved at 98% annualized and ASTY’s at 98%, so ASTN has the rougher ride and, at the same multiple, loses more to compounding.
- Can I hold ASTN or ASTY for a year?
- Both reset every day, so the multiple in the name applies to a single day and the daily results compound. Over a year the total is not the multiple times the year’s move, and in a market that falls and comes back it is reliably less. ETFIQ makes no recommendation either way.
- Which is cheaper, ASTN or ASTY?
- ASTN charges 1.31% a year and ASTY charges 1.31%, so ASTN is cheaper. Fees come from each fund's prospectus.
