Depositary receipt index
Depositary receipt index is a financial market index that measures the performance of a portfolio of depositary receipts representing shares of companies listed outside the market in which the receipts are traded. These indices provide investors with a benchmark for tracking the performance of internationally listed companies through depositary receipt programs, such as American depositary receipts (ADRs) and global depositary receipts (GDRs), without requiring direct investment in the underlying foreign securities.
Depositary receipt indices are designed to represent the performance of companies whose shares are made available to investors through depositary banks. The constituent securities are typically selected according to objective eligibility criteria, including market capitalization, liquidity, trading history, free-float, and listing requirements. Most depositary receipt indices employ float-adjusted market capitalization weighting, although alternative weighting methodologies may also be used depending on the objectives of the index.
These indices are widely used by institutional investors, asset managers, exchange-traded fund providers, and financial analysts for benchmarking, passive investing, portfolio construction, and measuring the performance of international equity markets. They also provide an efficient means of obtaining diversified exposure to companies from multiple jurisdictions while trading on a single securities exchange.
Depositary receipt indices form an important segment of global equity benchmarks by facilitating cross-border investment and improving access to international capital markets.
History
The growth of international investing during the late twentieth century increased demand for benchmarks tracking depositary receipts traded on major securities exchanges.
As the number of ADR and GDR programs expanded, index providers introduced specialized depositary receipt indices to measure their performance and support exchange-traded funds, index-linked products, and institutional portfolio management.
Today, numerous index providers publish depositary receipt indices covering global, regional, country-specific, and sector-specific markets.
Objectives
The principal objectives of a depositary receipt index are to:
- measure the performance of depositary receipts;
- facilitate international investment;
- provide transparent investment benchmarks;
- support passive investing;
- improve portfolio diversification;
- enable performance comparison.
These objectives promote efficient access to global equity markets.
Construction methodology
A typical depositary receipt index methodology specifies:
- constituent eligibility;
- security selection;
- liquidity requirements;
- free-float adjustments;
- weighting methodology;
- corporate action adjustments;
- rebalancing;
- reconstitution.
These rules are intended to ensure that the index remains representative, investable, and transparent.
Weighting methodology
Most depositary receipt indices employ:
- float-adjusted market capitalization weighting;
- equal weighting;
- capped weighting;
- factor weighting.
The weighting methodology depends upon the investment objectives of the index provider.
Example
Suppose a depositary receipt index includes the following securities traded as ADRs:
| Company | Country | Float-adjusted market capitalization |
|---|---|---|
| ABC Corporation | India | US$25 billion |
| XYZ Holdings | Brazil | US$18 billion |
| LMN Industries | South Korea | US$12 billion |
If the index employs float-adjusted market capitalization weighting, each company's weight is determined by its proportion of the aggregate float-adjusted market capitalization of all constituent depositary receipts.
Relationship with depositary receipts
A depositary receipt index consists primarily of depositary receipts representing underlying shares listed in foreign markets.
The index measures the collective performance of those depositary receipts rather than the underlying domestic shares directly.
Relationship with American depositary receipts
Many depositary receipt indices include American depositary receipts listed on U.S. securities exchanges.
These indices enable investors to monitor the performance of foreign companies accessible through the U.S. capital markets.
Relationship with global depositary receipts
Some depositary receipt indices include global depositary receipts traded on international securities exchanges.
Such indices provide broader international market coverage beyond a single jurisdiction.
Relationship with exchange-traded funds
Many exchange-traded funds seek to replicate the performance of depositary receipt indices.
These funds provide diversified exposure to international companies through a single investment vehicle.
Relationship with passive investing
Depositary receipt indices are widely used in Passive investing.
Index-tracking funds replicate the composition of the benchmark rather than selecting securities through active management.
Relationship with index mathematics methodology
Index mathematics methodology specifies:
- index calculation formulas;
- Index divisor adjustments;
- return calculations;
- treatment of corporate actions.
These mathematical rules govern the calculation of depositary receipt indices.
Relationship with index rebalancing
Index rebalancing periodically adjusts constituent weights according to the published weighting methodology.
This process ensures that the index continues to reflect its intended market exposure.
Relationship with index reconstitution
Index reconstitution periodically reviews constituent eligibility and adds or removes depositary receipts according to the published methodology.
This helps maintain the representativeness of the index.
Applications
Depositary receipt indices are widely used in:
- international portfolio management;
- exchange-traded funds;
- institutional asset management;
- investment benchmarking;
- financial research;
- passive investment strategies.
They facilitate investment in companies across multiple jurisdictions.
Advantages
Depositary receipt indices provide several important benefits.
They offer diversified international exposure, transparent methodologies, efficient benchmarking, broad market accessibility, and support for passive investment products.
They also enable investors to access foreign companies through familiar domestic trading platforms.
Limitations
Depositary receipt indices remain subject to market risk, currency fluctuations, geopolitical developments, and differences between depositary receipts and their underlying shares. Liquidity may also vary among constituent securities depending on the underlying market and the trading volume of individual depositary receipt programs.
Methodological differences among index providers may result in variations in constituent selection and weighting.
Importance
Depositary receipt indices play an important role in global capital markets by providing standardized benchmarks for internationally traded depositary receipts. They facilitate cross-border investment, support passive investment products, and enable investors to measure the performance of foreign companies through securities listed on domestic exchanges.
