Money market ¹
Long stock value
If I follow the footnotes, I see an excellent explanation by TD Ameritrade of what this "cash" and "money market" stuff is all about. Here is how they put it when explaining "money market":
This is the interest- or dividend-earning cash you hold in a sweep vehicle; this money can be withdrawn or used to buy securities. Your money market balance also includes accrued interest that will be paid at month-end.
As with most things related to the Series 7--this is not rocket science. It just takes some time to understand what's going on. Only at that point can you really do well on an exam question about SIPC or "cash" balances.
