The AdProfs AdTech Index™ is designed to track the stock market performance of publicly traded companies that provide advertising technology software and services. By advertising technology, we mean software that enables targeting, delivery, and analysis of digital advertising campaigns.

Last updated: May 30, 2024

Our intention is to provide a tracker for “pure-play” ad tech stocks. We, therefore, only include companies that derive the majority of their revenue from advertising technology and related services. This means that we exclude companies with significant ad-tech businesses if it isn’t their primary source of revenue.1 We also require that ad tech revenue is derived from digital ad campaigns served on third-party digital property (rather than the company’s owned and operated properties). Walled Gardens are therefore excluded, despite having significant ad-tech businesses.2 Finally, revenue must primarily be driven by proprietary technology, such as the licensing of such technology and any services associated with operating it.3 Agency Holding Companies are excluded, as their revenues are primarily generated through services related to the operation of third-party technology.

Index Constituents

On January 1, 2020, the following companies were added to the index:

  • The Trade Desk ($TTD)
  • Criteo ($CRTO)
  • Magnite ($MGNI)
  • LiveRamp ($RAMP)

Eligibility Criteria

All companies included in the AdProfs AdTech Index™ are selected by AdProfs upon meeting the eligibility criteria set out below:

  • Security type: common stock and ordinary shares listed on an eligible stock exchange.
  • Classes of securities: one security per company is permitted.
  • Eligible exchanges: Nasdaq Stock Market, New York Stock Exchange, and London Stock Exchange.
  • Industry / sector: the company must derive most of its revenue from advertising technology software and services. Furthermore, with respect to its ad tech revenue, the majority must be related to digital ad campaigns served on third-party properties and the licensing of the company’s proprietary technology and any services associated with operating it. As not all companies segment revenue in such a manner in their financial reporting, AdProfs will determine whether a company meets this eligibility requirement based on certain assumptions it makes as to the company’s business.
  • Market capitalization: the issuer has a minimum market capitalization of $500 million.
  • Other: the issuer has not entered into a definitive agreement, which would result in the security no longer being eligible and is not in bankruptcy proceedings.

Constituent Weighting

The AdProfs AdTech Index™ is an equal-weighted index. All index securities have equal index market capitalization at the time that they are added to the index.


The AdProfs AdTech Index™ is reconstituted twice a year. On January 1 and July 1 (or the first trading day after that, if it happens to be a non-trading day), we will remove issuers that no longer meet our eligibility criteria and add issuers that do.
