Currently I have 60% of my portfolio in VOO.
The rest (growth section) I have allocated to QQQM, SPMO and VGT.
Currently thinking about reducing or removing QQQM and adding AVUV, VXUS and possibly XMMO. (This is all contained in the 40% growth section outside of VOO. Do these changes make sense? Or would sticking with QQQM be better? How would you organize the growth section of a portfolio after having a foundation in the SP500?
