I didn't get directed to the chart you wanted me to see.
I am looking for where the money went on the 15th, not that I really expect to find it. I am not saying that was an evil genius or smersh behind the panic, but electronic funds moved, have to have a destination.
OK, when you sell off the “money market” mutual funds, you roll out of a mutual or “sweep” fund, and you’re left in cash, which has a 0.0% yield.
The money is still in your account, so technically it didn’t move anywhere, just as when you buy or sell a stock in your accounts, your money didn’t “go” anywhere - it was just buying or selling an asset held in your account. So the money didn’t have to “go” anywhere, it was just pulled out of the money market funds.
