Let Exxon Out of The Naughty Corner and Back Into the Dow Jones Index

In August 2020, Exxon Mobil Inc., the largest American oil company, was expelled from the Dow Jones Industrial Average, the world’s most famous stock index. It was described at the time as green triumphing over greed. Nearly three years later, the mood has changed. ESG isn’t the coolest financial trend; neither is divesting from oil companies. Regardless of whether the expulsion was right or wrong, the time has come to reverse it.

Sending Exxon to the naughty corner hasn’t hurt it. Since its exclusion, breaking a 92-year-long membership, it has outperformed the index, delivering total returns including reinvested dividends of 212% compared with 25% for the index. Its market value has also surged to $438 billion, from $168 billion the day it was kicked out. Salesforce Inc, the software company that replaced Exxon in the Dow, is currently worth $200 billion.

Exxon isn’t alone. Of the top 15 American companies by market value, eight aren’t part of the index, including Google parent Alphabet Inc., Warren Buffett’s Berkshire Hathaway Inc., and Tesla Inc., the business controlled by the world’s richest man, Elon Musk.

The Dow is an imperfect representation of the American economy. It only includes 30 blue-chip companies across multiple sectors and excludes transportation and utilities. Its weighting methodology, by share price rather than market capitalization, is problematic. Still, the index has stood the test of time and plays a big role in the collective imagination of the investment community.

Who’s in and who’s out is the job of the so-called “Averages Committee,” formed by three executives from S&P Global Inc., the company that owns the index, and two from The Wall Street Journal, because the index was created by the newspaper’s co-founders Charles Dow and Edward Jones. There aren’t any quantitative rules to decide the membership — just broad guidance: “Typically, a stock is added only if the company has an excellent reputation, demonstrates sustained growth, and is of interest to a large number of investors.”
