   "a": "Over the window to Sep 11, 2026, MDY moved \u22121.9% and MYY returned +3.1%. 1 times that move is +1.9%, so the fund came out 1.2 points ahead of it."
  },
  {
   "q": "Why does MYY not return -1 times over a year?",
   "a": "Because it resets daily. MYY aims at -1 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 -1 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."
