CEO Turnover and Relative Performance Evaluation: How Owners Should Judge the Chief Executive They Hired

When a hired CEO misses the numbers, an owner has to work out whether the problem is the executive or the market before paying for another transition.

An owner who steps back and hires a chief executive keeps one decisive power: the ability to replace that person. The hardest time to use that power well is a weak year, when the numbers disappoint and patience runs out. Our thesis is that the fair test of a hired CEO is relative performance evaluation. That means judging the company's results against rivals facing the same conditions, not against the budget, last year or the owner's memory of running the business. At least one major board adviser treats evaluation as something to design rather than improvise: Spencer Stuart presents its board evaluation handbook as a guide to processes that produce real insight, open conversation and steady improvement. An owner deciding whether to keep a CEO should meet the same standard, because a flawed scorecard can be fixed and a mistaken dismissal cannot be undone.

Bad CEO or bad market

Every result a CEO reports combines two things: the decisions the executive made and the conditions nobody in the building controlled. Raw numbers can't pull those apart. Falling sales in a year when the whole sector shrank tell an owner very little about the person in charge. A record year in a booming market can hide a leader who captured less of the boom than rivals did. Relative performance evaluation removes the part that everyone shares. If peers fell and your company fell less, the executive may have done well. If peers grew and your company stood still, that gap is the signal to investigate.

The shared part is concrete. NACD's Q3 2026 survey of 125 public company directors found economic conditions, geopolitical volatility and competition for AI talent at the top of fourth-quarter board agendas. In our reading, pressures like these hit a company and its competitors together. An owner who judges a CEO only on absolute results during such a period is partly grading the economy and pinning the grade on one person.

The logic works in both directions, and that is what makes it fair. It protects a capable executive from blame for a downturn, and it stops an average executive from taking credit for a rising tide. Neither outcome depends on how the owner feels about the hire.

The mirror in the boardroom

In our reading, owners who hand over the CEO job face a particular hazard: they default to measuring the hire against themselves. The founder remembers how quickly they used to decide, which customers they would have called and which hires they would never have made. The comparison feels natural, but it sets the executive against a different person working in a different period under different conditions. It also gives the owner no way to separate luck from skill on either side.

It also ignores how much the job changes. Spencer Stuart argues that each stage of a CEO's tenure requires "pivotal shifts in their thinking and behaviors" as the relationship between board and chief executive develops. We read that as a reminder that the owner's role changes too. The person who once ran operations now oversees them. The hire may be doing work the founder never had to do, such as building formal systems where the founder relied on instinct. Judging that work by the founder's habits misreads the assignment.

A practical safeguard is to write down, before any review, what evidence would show the hire is failing, without any reference to how the owner would have handled things. If the list reads like a description of the founder's style, it isn't a scorecard.

Build the peer set before you need it

The most important design choice is the comparison group, and it should be set early, ideally when the CEO is hired. In our reading, a peer set picked after a bad year risks being chosen to support a conclusion already reached. Spencer Stuart's Board Index, now in its 41st year, tracks board composition, governance practices and director pay across the S&P 500. In our reading, a mid-sized private company has no ready-made equivalent, so the owner has to build one.

That group can draw on listed competitors in the same segment, industry association figures, trade data, and what shared customers and suppliers say. In our reading, the best metrics are the ones that can be measured the same way for peers: revenue growth against the peer middle, gross margin against the peer range, share of key accounts and customer retention. The goal is direction, not precision. If the business keeps landing near the bottom of its group on the metrics the owner and CEO agreed on, the market explanation gets weaker each quarter.

Agreeing on the peer set with the CEO matters as much as choosing it. An executive who helped define the yardstick has less room to dispute it later, and the owner has less room to move it.

Leading indicators and a review rhythm

Peer-relative results are lagging measures, so they arrive well after the decisions that shaped them. An owner who waits only for those results may lose a year learning what earlier signals could have shown. Leading indicators fill the gap. They include the health of the sales pipeline, whether key people stay, progress on milestones the CEO committed to, customer complaints and the strength of the management team the executive is building. None of them proves skill on its own. In our reading, though, a consistent pattern across them is the earliest evidence an owner can get.

When reviews happen deserves as much thought as what they cover. Research summarized by NBER on nursing home inspections found that 74 percent of inspections take place 40 to 60 weeks after the previous one, which makes them easy to anticipate. NBER's summary of the study by Ashvin Gandhi, Andrew Olenski and Maggie Shi puts the consequence plainly: "They appear to devote more effort to patient care when inspections are approaching." The setting is very different, but in our reading the lesson carries over. A CEO reviewed once a year at a fixed moment has a reason to perform for that moment.

As we see it, a sensible rhythm pairs a light quarterly look at leading indicators with a full annual review against peers, while leaving the owner free to ask questions in between. The quarterly checks surface steady drift early, and the annual review is where peer-relative results get weighed. What matters is that the CEO knows the whole year counts, not only the weeks before the formal meeting.

Before you pay for a second transition

When the scorecard flags trouble, sort the evidence into three cases. If the company trails its peers on results and the leading indicators are also weak, the case against the hire is strong. If the business fell roughly in line with peers while the pipeline, people and milestones held up, the evidence points to bad luck. Firing the CEO in that case trades a known executive for an unknown one facing the same market. If the picture is mixed, our reading is that specific, time-bound goals serve the owner better than an immediate exit.

Whatever the verdict, plan the next step before acting on it. Spencer Stuart notes that transitions in independent board leadership are "too often left to chance," and argues that private equity firms that plan succession early can face less disruption, keep momentum and protect exit value. In our reading, a mid-sized company's owner has a similar interest in continuity, with or without a fund's timetable. An outside voice helps too. A director or adviser who didn't make the hire can test whether the owner is looking at the peers or in the mirror, and NACD says its network includes more than 20 local chapters where directors work through questions like this together.

The practical work fits into one quarter. Sit down with the CEO and agree on the peer group and the few metrics you will compare against it. Add the leading indicators you will check between annual reviews, and put the quarterly and annual dates on the calendar now. Write down in plain terms what result would justify a change, and leave the founder's own style out of it. Then let the scorecard, not the mood of a bad year, decide whether you have a bad hire or a bad market.
