Key insights
- The post discusses the potential benefits of adding a small equal-weight allocation to a multifactor ETF portfolio to improve diversification. While the discussion is relevant to portfolio construction, its direct impact on the broad US equity market is limited. A slight positive influence is assigned due to the potential for improved risk-adjusted returns through diversification.
I’m running a 25×4 multifactor portfolio:
- 25% World Momentum * 25% World Quality * 25% World Enhanced Value * 25% EM IMI
These three developed‑market factor ETFs cover most of the MSCI World’s market cap but only about half of its constituents. I’m considering adding a small Equal Weight core (5–15%) to broaden diversification and include the neutral companies that don’t show up in factor screens.
For those who use factor strategies: does adding a small Equal Weight allocation meaningfully improve breadth, or is it unnecessary in a multifactor framework?
Thanks for any insights.
