The quantum sector at a glance. Rather than tracking any one company, the Quantum Pure-Play Index follows the 14 listed companies whose main business is quantum, equally weighted, and compares them with the Nasdaq-100 and the Defiance Quantum ETF (QTUM). Prices are end-of-day. How the index works.
Prices may be out of date. The latest close we have is 9 Oct 2026; the price feed hasn't updated since.

How the index works
- Equal weight, rebalanced daily. Each trading day the index moves by the average daily return of its members, so a $2 billion company counts as much as a $20 billion one. That makes it a measure of the sector's breadth rather than of its biggest names.
- Who's in it. The Pure-Play Index covers listed companies whose main business is quantum computing hardware, quantum security or quantum software. Large technology companies with quantum programmes are tracked separately: their share prices mostly reflect other businesses.
- New listings. A company joins on the day it starts trading under its own name (for SPAC deals, the day the merger closes) and counts from that day's close. Listing-day moves and pre-merger shell prices are never in the index, and history is never back-filled.
- Prices. End-of-day closes adjusted for splits and dividends, from Yahoo Finance, refreshed every six hours. Figures can be delayed or revised.
- Base. 100 on 2 Jan 2024.
