Alternative investments encompass any asset class outside of traditional publicly traded equities, fixed income, and cash. For CFA Level I, you need to understand five major categories and the role each plays in portfolio construction.
**1. Hedge Funds**
Hedge funds are pooled investment vehicles that use diverse strategies — long/short equity, global macro, event-driven, relative value — to generate returns that are less correlated with broad markets. For example, Bridgewater Capital might run a global macro fund with $8.2 billion AUM that profits from interest rate differentials between Japan and the US, regardless of whether equity markets go up or down.
**2. Private Equity**
This includes venture capital (early-stage companies) and leveraged buyouts (mature companies). A PE firm like Redstone Partners might acquire Harmon Manufacturing for $450 million using 60% debt and 40% equity, restructure operations over 5 years, and exit at $780 million. The illiquidity premium is the key return driver.
**3. Real Estate**
Both direct property ownership and indirect vehicles like REITs. Real estate provides inflation protection because rents typically adjust upward with prices. A commercial REIT portfolio yielding 5.8% with 2.1% annual rent escalations offers a natural inflation hedge.
**4. Commodities**
Physical assets like oil, gold, agricultural products. Commodities are unique because their returns come from three sources: spot price changes, the roll yield (from futures contracts), and the collateral yield (interest earned on margin). Gold, for example, has near-zero correlation with equities over long periods.
**5. Infrastructure**
Long-lived physical assets like toll roads, airports, and power plants. Meridian Infrastructure Fund might own a portfolio of wind farms generating $34 million in annual revenue with 25-year government-backed power purchase agreements. These provide stable, bond-like cash flows with inflation linkage.
**Why Traditional Managers Care:**
The key benefit is **diversification**. Adding 10-20% alternatives to a 60/40 stock-bond portfolio can:
- Reduce overall portfolio volatility by 1.5-3.0 percentage points
- Improve the Sharpe ratio (return per unit of risk)
- Provide exposure to risk premiums not available in public markets (illiquidity premium, complexity premium)
**Common Pitfalls:**
- **Survivorship bias** inflates reported hedge fund returns by 2-4% because failed funds drop out of databases
- **Illiquidity** — most alternatives lock up capital for 3-10 years
- **Fees** — the classic "2 and 20" (2% management fee + 20% performance fee) significantly erodes net returns
