Have high returns on invested capital become more persistent for large companies?
Core argument: The aggregate return on invested capital for the information technology sector was 19% from 1970 to 2024 versus a median of 10.8%, and has on average exceeded the 75th-percentile company's ROIC since the Great Recession, meaning a small number of large companies determine the sector aggregate.
The data suggest that persistence in ROIC is up since 2000 and that large companies are the main beneficiaries of the implied expansion in CAPs. To illustrate the point, the aggregate ROIC for the information technology sector was 19% versus the median of 10.8% from 1970 to 2024. As striking, the aggregate ROIC for the sector has been greater on average than the ROIC for the 75th-percentile company (i.e., the ROIC below which 75% of data fall), since the Great Recession. This means a small number of large companies are determining the aggregate figure for the sector. From 1926 to 2025, the average listing time for a public company in Bessembinder’s database was 11.7 years, and the median listing time was 6.8 years. About 9% of listed companies at the beginning of 2026 were more than 50 years old. Modeling perpetual growth without considering mortality can create a mismatch. Exhibit 7 shows what happened to about 13,800 U.S. public firms that started trading between 1976 and 2019, excluding financial firms. For every 100 companies, 18 survived and 82 died. Of those that died, 43 were the result of mergers and acquisitions. The other 39 were delisted for reasons other than M&A, with the majority of those for “cause.” This happens when a company files for bankruptcy or fails to meet certain requirements set by an exchange.
