S&P 500 CEO transitions, 2010 to 2022

The external hire premium

Do externally hired CEOs cost more and deliver less than internal promotions? A study of 611 transitions, with a sports free-agency comparison.

Headline finding

What a company pays for an external hire does not predict the return that follows.

Companies often hire a CEO from outside, and they usually pay more to do it. The premium is real but small, about 9 percent over the predecessor. It does not buy a better result. The claim that external hires cost more and deliver less does not hold: the cost premium is imprecise, and the weaker returns are mostly selection. The robust finding, which holds under every control and repeats in four sports datasets, is simpler. What you pay for outside talent does not predict what you get.

Key numbers

The premium and the return

  • External pay premium: about +9% over the predecessor (p = 0.54)
  • Premium to stock return: p = 0.14
  • Premium to operating return: p = 0.45
  • Sample: 611 transitions, 158 external (25.9%)

Robust standard errors. Industry, size, and year controls.

The picture

If paying more bought more, the line would slope up. It does not.

premium paid → return delivered → what you would expect what the data shows

Premium over predecessor against the return that followed, for external hires. The fitted slope is near zero (p = 0.14 on stock performance, 0.45 on operating performance). Scatter is illustrative.

What this research tracks

Four measures, plus the split everything rests on

For each CEO change, the study first records whether the new CEO was promoted from within (internal) or brought in from outside (external). Then it measures four things.

  • Pay. What the new CEO earns against the departing CEO. This is the premium.
  • Stock performance. The return to shareholders, Total Shareholder Return (TSR), measured against the market.
  • Operating performance. Return on Assets (ROA), net income divided by total assets.
  • Tenure. How long the new CEO stays in the job.

The question

Does the premium buy a result?

Whether the price paid for an outside CEO predicts the return the company gets. A backward-looking test, not a hiring tool.

The approach

Public data, frozen sample

Pay from SEC proxy filings, accounting from SEC XBRL, returns from public prices. The sample was frozen before any financial data was collected.
