Rebuilt every trading night.\n As of Nov 4, 2026, the top ten holdings are a median 50% of a theme ETF and 36% of a stock ETF.\n \n In plain words\n Concentration is how much of a fund sits in a few holdings. A fund with 500 stocks but 40% in its top ten is more concentrated than the count implies, so the usual test is the top-ten share.\n Theme funds are the most concentrated: the median has 50% in its top ten, against 36% for a stock ETF and 15% for a bond ETF. 50% of 406 theme funds put half or more into ten names. A concentrated fund moves more with its leaders, raising gains and losses alike. Every fund page shows the weight with its holdings date.\n Questions\n Is concentration the same as risk? It adds to it. A fund that leans on a few names moves more with them.\n How is top ten weight measured? The weights of the ten largest holdings in the latest filed list.\n Where do I see it?
