   "q": "What does IBB hold?",
   "a": "245 positions as published by its issuer for Oct 27, 2026, with the top ten at 50% of the fund. The largest are GILEAD SCIENCES at 8.6%, AMGEN INC at 8.2%, VERTEX PHARMACEUTICALS at 7.5%."

   "a": "Over the year to Oct 28, 2026 IBB returned +37.5% with distributions reinvested, against +13.6% for the S&P 500, so it finished ahead of the index by 23.9 points."

   "q": "What does IBB cost?",
