Empty Account
A brokerage account has no tax wrapper and no yearly limit, which is exactly why it sits last in the published order. The money you transferred is sitting in the account's cash position. It becomes invested only when you buy something with it — and the order you follow to get here matters more than the first buy.
Every reader sees the same three categories. This page teaches the kinds — it never picks one for you. Picking one for you, from your situation, is what advisers are licensed to do.
One fund built around a year — roughly your retirement year. It holds a mix of stock and bond funds and slowly shifts steadier as the year approaches. Different companies run theirs differently and charge differently.
Funds that copy a published list — for example, a list of large US companies, or a list spanning the whole stock market — instead of picking winners. Usually the lowest yearly cost on the menu, because copying is cheap to run.
Cash-like funds holding very short-term loans. Steady value, modest yield, barely any movement. This is where uninvested money often sits — parked, not growing.
