Many Happy Returns
By JEREMY J. SIEGEL and JEREMY SCHWARTZ
March 1, 2007;
Markets go up, and as Tuesday’s dizzying 416-point drop in the Dow reminds us, they go down too, sometimes in a big hurry. Still, we shouldn’t let this week’s jitters pass without noting that today is the 50th birthday of one of the world’s most famous benchmarks for stock-market returns, the S&P 500. Standard and Poor’s, the originators and keepers of the index, estimates that over $1 trillion is directly or indirectly tied to the performance of these 500 firms, selected to represent America’s economy.
From its inception on March 1, 1957, through the end of last year, the average annual return of the S&P 500 Index, which today comprises almost 80% of the value of all U.S. stocks, has been 10.83%, a return that most active equity managers have found very difficult to match. The changing composition of the index also mirrors larger changes in the economic landscape. Because of mergers, bankruptcies and other corporate changes, almost 1,000 new companies have been added to the index, as others were dropped, since its inception.
In 1957 the technology, health-care, and financial sectors, which today comprise almost one-half the index’s value, made up a mere 6% of the index. The financial sector was particularly small in the 1950s and 1960s since commercial and investment banks, as well as brokerage houses, were not included in the S&P 500 until the 1970s.
The biggest industrial sector in 1957 was “materials” — steel, aluminum, chemical, paper and mining companies. The materials and energy sectors made up half the value of the S&P 500 when the index was originated, compared to only 12% today. Still, the stocks in the original index were winners. By far and away the best performing is Altria Corporation, formerly known as Phillip Morris Corp. From March 1957 through December 2006, this cigarette manufacturer, which in 1980 diversified into foods, gave investors a 19.88% annual return, almost double the annual return of the S&P 500 Index. An investment of $1,000 put into Philip Morris in 1957 would have grown to $8.4 million by the end of 2006 — compared to a mere $168,000 accumulation in the S&P 500 itself.
Surprisingly, the second best performing stock of the original 500 was Thatcher Glass Co., a profitable milk bottle manufacturer in the early 1950s. When the baby boom turned into a baby bust and glass milk bottles were replaced by waxed cartons, Thatcher Glass was bought by Rexall Drug, which became Dart Industries, which merged with Kraft, and was eventually bought by Philip Morris in 1988. A $1,000 investment in the dominant manufacturer of an obsolete product turned into a $4.95 million bonanza for investors.
Other stocks in the 1957 index paid off big. Of the 111 original companies that have survived intact, 20 outperformed the index by an average of almost five percentage points per year. These include PepsiCo, Coca-Cola, Colgate Palmolive, Heinz, Wrigley, Procter & Gamble, Hershey and Tootsie Roll Industries. The pharmaceutical industry performed brilliantly for investors, as Abbott Labs returned nearly 16% per year, while Merck, Bristol Myers Squibb, Pfizer and Schering Plough, despite their recent troubles, all handily beat the S&P 500 Index.
The firms that dominated the original list did very well for their investors. AT&T was the largest stock in the index in 1957 with market capitalization of $11.2 billion (that capitalization would rank in the bottom 200 of today’s S&P 500 firms). The telephone monopoly known as “Ma Bell” was broken up in 1984, giving birth to the “Baby Bell” regional providers. AT&T was bought by one of its children, SBC Communications in 2005 and, through other acquisitions, worked itself back to the top 20 in market value. The 50-year return on AT&T, had you also held all the Baby Bells when Ma Bell spun them off 23 year ago, gave you a 10.77% annual return, virtually matching the index.
Another perspective: 12 of the 20 largest companies in the original 1957 index beat the performance of the index; and a portfolio of all 20 bested the index by almost one percentage point per year. The winners among these original stocks include all the oil companies (Mobil, Royal Dutch, Exxon, Shell, Amoco, Gulf, Chevron, Phillips and Texaco), as well as General Electric, IBM and Sears (thanks to Eddie Lampert and Sears Holdings). Union Carbide, Du Pont, Eastman Kodak, Alcoa, General Motors and U.S. Steel lagged the index but only one stock — Bethlehem Steel — lost all of its investors’ money.
Surprisingly, if an investor had bought a portfolio of all 500 companies that Standard and Poor’s placed in the index on March 1957 and held them until today, he would have not only handily beat the S&P 500 Index itself; he would have outperformed most money managers that have tried to beat it. This is truly remarkable — given that such an investor would have never purchased a single one of the nearly 1,000 new companies that were added to this famous index over the past half century.
Happy Birthday, S&P 500. You have certainly aged well.
