Plays the chart through its history. Pauses are where the data set a record or moved most.
Built from SEC filings and daily closes: combined market value over combined net income for the last four reported quarters. Not a forward P/E. Today’s members are used back in time.
How many years of current profits investors are paying for the largest U.S. companies. When the group line sits well above the median, a few very large, highly valued companies are lifting it.
