The Mechanics Behind the Index

Two views of the S&P 500. One puts the price against earnings. The other is a century of calendar-year returns, with a sandbox for paths that have not happened.

Desk

Earnings

Price overlaid with quarterly and trailing-twelve-month earnings. The fit, the rollover, and whether both tapes are up, mixed, or down.

Desk

Returns

Every finished year since 1900, on a curve. This year’s path is locked to the tape. The sandbox is where you type your own.
