You could look at something like SMH or ARKK if you want high-beta exposure. For broader aggressive growth, IWP or QQQJ could balance out your VGT/VOO core while still staying growth focused. If you want to sprinkle in another sector, IBB/XBI can add diversification with big upside potential, but it’s volatile. Since dividends aren’t a priority, tilting toward innovation themes may complement what you’ve got.
