A Wealth Manager Just Made a Case for Cutting Real Estate and Gold From Your Portfolio

A 40-year-old investor aiming for retirement in 20 to 25 years now has a stronger case for skipping standalone real estate and high-cost gold funds — even if the advice comes from an AI. When ChatGPT built a model portfolio for this investor, it followed textbook diversification: 50% U.S. stocks (VTI), 20% international (VXUS), 20% bonds (BND or AGG), 5% real estate (VNQ), and 5% gold (GLD). The total stock exposure landed at 70%, within standard guidelines for someone in their 40s.

Thomas Brock, a chartered financial analyst and certified public accountant, called the framework sound — but undercooked on growth. For an investor decades from retirement, he pushed total stock allocation to 80%. That means increasing international exposure to better reflect the global market, where non-U.S. equities make up about 40% of all publicly traded stock.

To fund the shift, bonds were cut. Volatility is a feature, not a flaw, at this stage. More equity means more compounding runway.

Then came the real break from convention: drop the real estate ETF entirely. VNQ, which holds REITs, is redundant. Broad market funds like VTI already include real estate companies. A separate 5% allocation doesn’t add diversification — it adds overlap.

Gold stayed, but not in the form ChatGPT picked. GLD was swapped for GLDM, an identical exposure with half the expense ratio — 0.05% versus 0.10%. That difference compounds over time. On a $100,000 portfolio, it saves $50 a year. Over 20 years, that’s over $1,100 in avoided fees, assuming reinvestment and 7% annual returns.

Finally, Brock added something the AI missed: a 2.5% liquidity reserve in a high-yield money market fund. It earns 3.5% to 4.0% — competitive with short-term bonds — and sits ready to deploy when markets dip. Cash isn’t dead weight. It’s dry powder.

The final structure — 80% global stocks, leaner bonds, no standalone real estate, cheaper gold, and a yield-bearing cash sleeve — isn’t radical. It’s refinement. It removes redundancy, cuts cost drag, and positions the investor to act, not just hold.
