 "questions": [
  {
   "q": "Did SRTY return -3 times IWM?",
   "a": "Over the window to Sep 11, 2026, IWM moved \u22121.1% and SRTY returned +4.2%. 3 times that move is +3.5%, so the fund came out 0.7 points ahead of it."
  },
  {
   "q": "Why does SRTY not return -3 times over a year?",
   "a": "Because it resets daily. SRTY aims at -3 times each day's move, and daily results compound. Over a run where the underlying falls and comes back, compounding a levered daily return leaves a holder behind what -3 times the period move would suggest; over a steady run in one direction it can leave them ahead. The longer the holding, and the more the underlying moves about, the further apart the two figures get."
  },
  {
   "q": "Which -3x IWM ETF tracked its stated multiple most closely?",
   "a": "2 issuers sell one. Over the days all of them have been trading, the table on this page ranks them by how far each finished from 3 times the underlying's move. ETFIQ does not rate funds; the order is the arithmetic."
