The Hedge Fund Talent Brief: Why a track record alone doesn’t travel

Psybil Insights  ·  October 2026  ·  4 min read

A five-year track record blends three things most diligence never separates: skill, market regime, and luck. Most funds price the blend. Almost none price the parts.

When bankers move into a portfolio manager position, 70% of them survive the transition. Fine. But only 4 of those 7 perform at a high enough level to maintain their position. A 40% success rate is bad. Mind you, the bankers taking these PM positions make it through due diligence and seem like good hires at the time. So what goes wrong, and what should a hiring team look for in their process?

Three findings from scientific assessments on why prior track records mislead hiring managers, and what actually predicts performance in a new position.

Part I  ·  Skill, Regime, or Luck?

Don’t confuse a great year with a great manager.

Someone’s track record shows you what happened, but it doesn’t tell you why. A manager who rode a rising rate cycle, a sector rotation, or a single concentrated winner can look identical, on paper, to a manager who built a repeatable process.

How can a hiring team see through a seemingly good (but unrepeatable) track record? They really need to dig into how position sizing behaved across different regimes. Did the same process produce results in more than one kind of market?

Otherwise, funds end up hiring managers without much certainty they will be able to bring similar results with them to the new position.

Part II  ·  Context Is Everything

Analysts, risk budgets, and prior mandates don’t come with the new candidate.

A resume rarely mentions the infrastructure underneath a top performer. A candidate who benefited from a deep research bench, a generous risk budget, and a flexible mandate cannot predict performance under a leaner team, a tighter limit, and a narrower mandate. The conditions that produced an impressive track record almost never exist in a new position.

Instead of finding out what a candidate achieved, hiring teams should ask who generated the ideas, who sized the positions, and who absorbed the losses when things went wrong. That is how they learn whether the candidate will bring desirable skills with them into a new PM position.

Part III  ·  What to Diligence Instead of the Resume

Test the process, not the outcomes.

Schmidt and Hunter’s meta-analysis found that raw years of experience predict future job performance weakly. It only accounts for 3% of future performance. Work sample tests and structured, validated assessments predict it about 8 to 9 times better, at 29% and 26% respectively. How a candidate generates an idea, sizes a position, and responds to being wrong says more about the next five years than how the last five years turned out.

We do not want to throw out a candidate’s prior performance. Structured assessments add context to a larger picture, telling a hiring team which part of the track record they can attribute to a candidate’s transferable skills.

Closing

Does your diligence process test skills, or take a story at face value?

Hiring a senior PM, promoting an analyst into a book of their own, and planning succession for a departing manager all carry the same exposure: a decision made based on an unattributable track record instead of skills that will benefit your firm.

Structured assessments separate managers’ skill from the market that produced their impressive resumes.
