Why Diversification Still Matters
Diversification is often called the only free lunch in investing. By spreading investments across assets that don't move in lockstep, you can reduce portfolio risk without sacrificing expected returns. The 2022 market demonstrated this perfectly: while stocks dropped 20%, diversified portfolios with bonds, commodities, and real assets fell far less.
Correlation Is the Key Concept
Effective diversification isn't about owning many things — it's about owning things that behave differently. Holding 20 tech stocks isn't diversification. The goal is combining assets with low or negative correlations: when one zigs, another zags. Stocks and bonds have historically provided this balance, though the relationship can shift during certain market regimes.
Alternative Asset Classes
Beyond traditional stocks and bonds, consider:
• Real estate (REITs or direct ownership) — inflation hedge with income • Commodities — portfolio insurance during inflationary periods • Treasury Inflation-Protected Securities (TIPS) — guaranteed inflation protection • International developed and emerging markets — geographic diversification • Small-cap value stocks — higher expected returns with different risk profile
The Simple Diversified Portfolio
A well-diversified portfolio doesn't need to be complicated. A four-fund approach covers most bases:
1. US Total Stock Market (40-50%) 2. International Stock Market (20-30%) 3. US Total Bond Market (15-25%) 4. Real Assets — REITs or TIPS (5-15%)
Rebalance annually to maintain target allocations and systematically buy low / sell high.
