Semiconductor Companies' Share of the S&P 500

## What this measures

The market value of today's S&P 500 members that make chips or chipmaking equipment, as a percent of the market value of every company in the S&P 500.

## Why it matters

A fund that tracks the S&P 500 is now partly a bet on semiconductors. This is how large that bet is.

## How to read it

Percent of the index's total market value. Companies outside the S&P 500 (Arm, ASML and smaller chipmakers) are left out of the numerator.

## What it does not say

It uses today's S&P 500 members and current share counts back in time. It is total market value, not the index's float-adjusted weight.
