Diversification in Alternative Investments
Definition
Diversification is the practice of spreading investment across different assets, asset classes, strategies, or geographies to reduce the overall risk of a portfolio. In the context of alternatives, diversification typically refers to the role these investments play in reducing dependence on traditional equities and fixed income.
Why It Matters
A portfolio of equities and bonds is exposed to broad market risk – when both asset classes fall together (as happened in 2022), there is no internal hedge. Alternative investments are often described as offering “low correlation” to public markets, meaning they do not move in lockstep with equities or bonds.
How Alternatives Contribute to Diversification
| Asset Class | Correlation Driver | Diversification Benefit |
|---|---|---|
| Private Equity | Private company fundamentals | Partial (correlated long-term but smoothed) |
| Private Credit | Contractual debt cash flows | Low to moderate vs equities |
| Hedge Funds | Strategy-dependent | Can be very low (market-neutral) |
| Real Estate | Property fundamentals, rent | Moderate; inflation hedge value |
| Infrastructure | Regulated revenues, long contracts | Low; inflation linkage |
| Commodities | Supply/demand of physical goods | Low; useful inflation hedge |
Important Caveats
- Private market diversification is partly illusory. Because private assets are valued infrequently (quarterly), their measured correlation to equities appears low. In a severe downturn (e.g., 2008), private market valuations eventually reflect the same losses as public markets – with a lag.
- Correlation increases in stress events. Many assets that appear uncorrelated in normal markets move together during crises. Hedge fund strategies that appear diversifying can become correlated when liquidity dries up.
- True diversification requires different return drivers. The best alternative diversifiers are those with returns driven by genuinely different factors – e.g., infrastructure revenues linked to regulation, not equity markets.
Simple Example
A pension fund has 60% equities, 40% bonds. In a market drawdown, both fall. The fund adds 10% infrastructure allocation funded from equities. The infrastructure assets generate stable rental-equivalent income with minimal link to equity prices. In the next downturn, the portfolio’s total loss is smaller.
