The sectors
Each sector read as one company: its members’ market values summed over their trailing earnings for the multiple, their revenue and net income summed for the margin and the growth. Communication Services carries the lowest multiple at 15.7 and Healthcare the highest at 39.0, against 25.8 for the market. Each sector name opens its page: valuation, profitability, growth and balance sheets against the market and the sector’s own fund, and every company in it.
Valuation at the close of October 30, 2026; margins, growth and leverage for Q2 2026, the latest complete quarter. Sectors from the SIC-based classification on the company pages; Semiconductors is an industry group inside Technology (Semiconductors and Semiconductor Equipment), listed last.

Method
- Aggregates
- the covered companies read as one company: sums of market value, earnings, revenue, equity and cash flow over the companies carrying both lines of a ratio, so a loss-maker lowers the market's P/E as it would in an index; a ratio with a non-positive denominator is withheld, so a sector's P/E has no reading while its trailing earnings are a loss in sum (the earnings yield, earnings over value, is shown negative instead).
- Medians
- the median company, over companies with a positive denominator (and, for P/E, positive trailing earnings).
- Point in time
- a week's value is the close on its last trading day times the shares on the newest quarterly filing first filed by that day; the earnings, revenue, equity and cash flow are that quarter's trailing twelve months, so a past reading uses only what had been filed.
- Quarters
- fiscal quarters are assigned to calendar quarters by their midpoint; a quarter is complete once at least 90% of the prior quarter's reporters have filed it.
- Survivorship
- the companies are today's, so the early years are the history of the firms that survived to be covered now, and the first weeks are dropped until coverage reaches half its peak.
531 companies, 458 with a trailing P/E at the latest close. Income statements, balance sheets and cash flows from each company's SEC 10-K and 10-Q filings (this site's extract); split-adjusted daily closes from a market data vendor. Every figure is computed from the filings; nothing here is a forecast or a recommendation.
