Purchasing ETFs when (pretty much) everything else is maxed out
Most ETFs are index funds, meaning you get built in diversification so that any one stock going down won't hurt the overall performance much. You can also get essentially the same index funds by directly purchasing them from the mutual fund company. To buy an ETF you need a brokerage account and have to pay a transaction fee. Buying only $1000 at a time the broker transaction fee will eat too much of your money. You want to keep such fees way down below 0.1%. Pay attention to transaction fees and fund expense ratios.  Or buy an equivalent index fund directly from the mutual fund company. This generally costs nothing in transaction fees if you have at least the minimum account value built up. If you buy every month or two you are dollar cost averaging, no matter what kind of account you are using. Keep doing that, even if the market values are going down. (Especially if the market values are going down!)  If you can keep doing this then forget about certificates of deposit. At current rates you cannot build wealth with CDs.
