A fund at 85% active share has 15% of its money in index names at index weights. Across the thematic ETFs ETFIQ tracks, the typical fund holds 32% of its weight in stocks the S&P 500 already owns.\n ETFIQ computes it from each fund's latest filed holdings against the S&P 500 book, matching securities on CUSIP, then ISIN, then ticker, then a normalized name. Overlap is the sum of the smaller weight of every security the two hold in common. Active share is one hundred minus that.\n The number matters because you buy a thematic fund for the part that is different. If most of the fund is index names you already own, the theme is a smaller bet than the name suggests, and you pay the fee on the whole fund, not just the differing part.\n ETFIQ also shows the fee divided by the share that differs. That is the price of the active decision.\n On ETFIQ today\n Ticker Fund Theme In the S&P 500 Active share Fee Fee for the differing part \n PDBA Invesco Agriculture Commodity Strategy No K-1 ETF Agriculture 0.0% 100.0% 0.59% 0.59% \n DRAI Draco Evolution AI ETF Artificial intelligence 0.0% 100.0% 1.32% 1.32% \n DRGN Themes China Generative Artificial Intelligence ETF Artificial intelligence 0.0% 100.0% 0.39% 0.39% \n KAIT KraneShares Asia AI Technology ETF Artificial intelligence 0.0% 100.0% 1.00% 1.00% \n BBC Virtus Biotech Clinical Trials ETF Biotech 0.0% 100.0% 0.65% 0.65% \n GXDW Global X Dorsey Wright Thematic ETF Broad innovation and megatrends 0.0% 100.0% 0.50% 0.50% \n LFSC F/m Emerald Life Sciences Innovation ETF Broad innovation and megatrends 0.0% 100.0% 0.54% 0.54% \n MJ Amplify Alternative Harvest ETF Cannabis 0.0% 100.0% 0.75% 0.75% \n \n Where to next\n Every thematic ETF The vocabulary Are thematic ETFs different from the index?
