  },
  {
   "q": "Why does MZZ not return -2 times over a year?",
   "a": "Because it resets daily. MZZ aims at -2 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 -2 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."
