I'm willing to bet there are exactly 0 individuals in the U.S. who keep $100M in a personal investment account under their name. If there are any, they didn't get their money from managing money well, as there are a variety of setups that are far more tax efficient. If they invest in these vehicles, then generally yes, the vehicle needs to file the 13F per https://www.sec.gov/answers/form13f.htm If you need the answer for a real question vice settling a bet among accountants, call the SEC.
Thanks for the info. I assure you there are multiple investors with $100 million plus in trading accounts, heck, I know one with 50 in a checking account paying zero. There is MAD money out there now. But yes, you are 100% correct, the money did not come from trading the financial markets
I stand corrected then, crazy. I think the intent was not for individuals managing their own accounts to file, per the last part of "In general, an institutional investment manager is: (1) an entity that invests in, or buys and sells, securities for its own account; or (2) a natural person or an entity that exercises investment discretion over the account of any other natural person or entity. Institutional investment managers can include investment advisers, banks, insurance companies, broker-dealers, pension funds, and corporations." In addition, the first part is specific in stating "entity" for (1) and "natural person or entity" for (2), so that again would lean toward it not being required for a natural person managing their own money. However don't take the advice of some jackass on the internet if you really have someone in that situation!
