These days there are financial firms that have a cumulatively large position in some stocks and markets like the london Copper Market where Jon Koplik posted back in december that one master entity held 90% of the entire physical inventory of copper at the London Metals Exchange. It's a fact of the markets of 2020( I'm going to start using the 2020 expression for where the markets are heading as we are now well into the seoond decade of the 21st century).... that you have financial entities that are aggregators of positions in stocks, commodities and numerous other areas where the financial firm that is the aggregate holder can have a huge % of the float of a stock or the physical stock of a commodity, but it can technically subdivided among a number of different accounts and companies that companies such as JPM provide services to. Remember Bear Sterns was a massive player in number of energy markets, commodity markets and other areas of concentration and now it's all subsumed by JPM Chase... remember the good old days in the early 1970's ... they would talk about the New York City Money Center Banks that were big holders in the private stock of the Federal Reserve. The used to talk about Manufacturers Hanover Bank, Chemical Bank, Citibank, Chase bank that merged with the Manhattan Bank, JP Morgan, The Bank of New York and Bankers Trust. well Chemical Bank went out and bought up Mannie Hannie. and then Chemical Bank bought Chase, although they kept the Chase branding. Deutsche Bank bought Bankers trust... smart move. and then JP Morgan was brought into the Chase fold. At this point many of the equity owners of the US Federal stock have been consolidated into a smaller number of entities who control just that many more accounts. This type of response is utilized in Jon Koplik's Dec 21st post where he points out that a single trader is listed as owning 90% of the physical copper warehoused for the london Metals Exchange. JP
