Episode notes
Fund Design Locked In The Risk
- A legacy fund-of-funds couldn't be fixed by better weights because its product design forced identical bets across managers.
- Vikram realized risk was decided by the investment universe and design, not by subsequent optimization.
Rotate Vulnerability Don’t Capitulate
- When models signal defensiveness but the narrative is bullish, hedge by rotating exposure rather than selling everything.
- Vikram suggests keeping market exposure but shifting from high-multiple growth to profitable quality to change vulnerability.
Use Adaptive Macro Regimes Not Binary Labels
- Binary cycle labels miss conditionality; same macro readings can precede very different outcomes.
- Vikram uses rolling quantiles and adaptive weights (growth, labor, inflation, fiscal) to avoid fixed thresholds like GDP<2% = recession.
