Core w/ Value vs. Core w/ Value + Momentum
I am looking for guidance on upgrading my portfolio. Currently, I just hold VTI + VXUS at 70% / 30% split. I like a slight USA tilt, but want to remain close to world weight. I have a relatively high risk tolerance. I will try to set it and leave it as but once a year for rebalancing. I am looking for the highest expected returns over a long horizon; I am about 30 years from retirement. Which of these portfolios would you choose:
Core holdings w/ value ETFS:
VOO: 50%
AVUV: 15%
VEU: 15%
AVDV: 10%
AVES: 5%
Stock picks: 5%
OR
Core holdings w/ value + momentum ETFs
VOO: 40%
AVUV: 15%
SPMO: 10%
VEU: 10%
AVDV: 10%
IDMO: 5%
AVES: 5%
Stock picks: 5%
I am thinking to go with VOO/VEU over VTI/VXUS for core because I want to eliminate small growth stocks from my portfolio, which I think tend to perform the worst. On my portfolio images, "GOOG" is in place for stock picks, as it will be core holding. However, I do like to tinker around a bit and so having 5% to tinker with will help my scratch that itch.
Which portfolio would you choose and why?
