Track record across FULL market cycles
Ask for at least five years of Time-Weighted Rate of Return (TWRR), and insist the window spans real stress — the March 2020 COVID crash and the 2022 rate-hike correction. TWRR strips out the timing and size of cash flows, so it reflects the manager's skill rather than when money happened to arrive. Prefer rolling returns against an appropriate benchmark over a single point-to-point CAGR.
The mistake it prevents — Inception-date luck: a flattering start date and one strong year passed off as a process.
