M1 Finance’s Expert Pies are pre-built portfolios in which you can invest for free. This is great for the investor who wants a lazy portfolio for the majority of their investing horizon. Their category of “General Investing” Expert Pies allow you to select a portfolio for broad market exposure based on risk tolerance. These are comprised of low-cost Vanguard ETF’s.
M1 claims that these portfolios are mean-variance optimized (think Modern Portfolio Theory and Harry Markowitz). This ends up making them unnecessarily complicated in my opinion and results in uneven allocations and a heavy weighting to international (ex-US) stocks. More specifically though, I believe these portfolios are suboptimal for the following reasons:
- They incorporate corporate bonds. We know treasury bonds are superior.
- They use small-cap growth stocks, which haven’t paid a risk premium historically.
- Bond duration is skewed too short/low in my opinion for what is supposed to be an “aggressive” portfolio.
- Similarly, bond allocation, at 14%, is still too high in my opinion to be considered “aggressive.”
At the time of writing, M1’s Aggressive Portfolio pie looks like this:
- 29% VEA – Developed Markets
- 26% VOO – S&P 500
- 14% VB – Small-Cap Blend
- 11% VCIT – Intermediate-Term Corporate Bonds
- 6% VWO – Emerging Markets
- 6% VO – Mid-Cap Blend
- 5% VNQ – U.S. REITs
- 3% BNDX – Total International Bond Market
In improving this portfolio, we’re essentially just going to fix the things I mentioned above:
- International stocks inarguably offer a diversification benefit, but their global market weight at about 40% seems too high. I choose to use a 20% allocation to international stocks. We can use VXUS for this.
- In avoiding small- and mid-cap growth stocks, we’ll use their Value counterparts – VBR and VOE.
- We’re going to use treasury bonds and eliminate corporate bonds.
- In making the portfolio truly more “aggressive,” bond holding will be set at 10% instead of 14%, and will utilize long-term treasury bonds with a longer average duration. We’ll use VGLT for this. Since the portfolio has such a small allocation to bonds, we don’t actually need any international bonds.
- We’ll use a slightly higher allocation to REITs – in this case 10% – for the diversification benefit.
My resulting improved Aggressive Portfolio then looks like this:
- 30% VOO
- 20% VXUS
- 20% VOE
- 10% VBR
- 10% VNQ
- 10% VGLT
