NEW YORK — The Dow Jones industrial average is dumping Cool Whip for copays.
The Dow, perhaps the most widely known barometer of the U.S. stock market, announced Friday that it would boot Kraft Foods to make room for UnitedHealth Group, the insurance company.
The change takes effect Sept. 24. S&P Dow Jones Indices, which manages the average, said it was dropping Kraft because it is about to become a much smaller company after spinning off its North American grocery business.
The shuffle will not affect the level of the Dow, which closed Thursday above 13,500 and at a four-year high.
The formula used to calculate the average is recalibrated every time a company is added or dropped.
Kraft, which also makes Cheez Whiz and the familiar blue-box macaroni and cheese, had a short shelf life on the Dow. It was added during the financial crisis in September 2008, replacing crippled insurer American International Group.
UnitedHealth Group was added because of health care’s growing importance in the U.S. economy, said David Blitzer, chairman of the index committee.
The Dow included drugmakers Pfizer and Merck but no companies focused on health insurance.
UnitedHealth stock jumped $1.38 in early trading to $55.27, but later in the day it fell back and was flat.
The Dow is made up of 30 stocks.
A small committee, including the managing editor of The Wall Street Journal, which is owned by Dow Jones, decide which companies get added and dropped.
The purpose is to give investors an idea of how the entire stock market is performing.
It’s not operated like an investment portfolio, hunting stocks that will be most profitable.
