Investment Grade Corporate Bonds Investment Grade (IG) — corporate bonds of issuers with a credit rating of BBB-/Baa3 and above. This is the largest segment of corporate debt, combining acceptable risk with a premium over government bonds.

Sector Analysis of IG Index

| Technology | ~12% | High rating, low leverage |

Risks of IG Bonds
- Interest Rate Risk — high duration = sensitivity to rates
- Credit Spread Risk — spreads widen during stress
- Downgrade Risk (Fallen Angels) — downgrade to HY = forced selling
- Event Risk — M&A, LBO, change of business model
- Liquidity Risk — less liquid than government bonds
BBB — The Critical Threshold
The BBB segment has grown from 30% to 50% of the IG index over the past 20 years. Risks:
- Cliff risk — downgrade by one notch = transition to HY
- Forced selling — IG mandates are required to sell
- Recession scenario — mass downgrades may destabilize the market
