Neither figure predicts the next window: it depends on how much the underlying moves about."}},{"@type":"Question","name":"Are PST and TBX levered on the same thing?","acceptedAnswer":{"@type":"Answer","text":"Yes. Both are levered on 10-year Treasuries, PST at -2 times and TBX at -1 times the daily move."}},{"@type":"Question","name":"Which one decays faster, PST or TBX?","acceptedAnswer":{"@type":"Answer","text":"Decay follows how much the underlying moves about. Over this window PST\u2019s moved at 5% annualized and TBX\u2019s at 5%, so PST has the rougher ride and, at the same multiple, loses more to compounding."}},{"@type":"Question","name":"Can I hold PST or TBX for a year?","acceptedAnswer":{"@type":"Answer","text":"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\u2019s move, and in a market that falls and comes back it is reliably less. ETFIQ makes no recommendation either way."}},{"@type":"Question","name":"Which is cheaper, PST or TBX?","acceptedAnswer":{"@type":"Answer","text":"PST charges 0.95% a year and TBX charges 0.95%, so PST is cheaper. Fees come from each fund's prospectus."}}]},{"@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"ETFIQ","item":"https://etfiq.com/"},{"@type":"ListItem","position":2,"name":"Leveraged ETFs","item":"https://etfiq.com/leverage/"},{"@type":"ListItem","position":3,"name":"PST vs TBX","item":"https://etfiq.com/compare/leverage/pst-vs-tbx"}]},{"@type":"WebPage","name":"PST vs TBX: which held to its multiple?","description":"PST sets out to return -2 times IEF each day and TBX -1 times.
