ADR vs CDR
An ADR carries the foreign share's currency exposure into a US listing; a CDR wraps a mostly-US share in a daily-reset hedge and lists it in Canada in CAD.
The difference
Both are depositary receipts: you hold a certificate issued by a bank that represents an interest in shares held elsewhere, not the local shares themselves. From there they point in opposite directions. An ADR is a US-traded certificate representing shares of a foreign company, letting Americans buy non-US stocks in USD on US exchanges, at a fixed ratio of underlying shares that the bank sets to keep the ADR price in a typical US trading range. A CDR is a security issued by CIBC that represents a fractional interest in a foreign stock — mostly large U.S. names — and trades on a Canadian exchange in Canadian dollars, with a ratio that resets daily to maintain approximate currency neutrality. The sharpest contrast is currency: an ADR's price divides by the FX rate, so exchange-rate moves flow straight into what you see, while a CDR's built-in hedge removes most of the day-to-day USD/CAD swing at the cost of an embedded FX spread.
Side by side
| Aspect | American Depositary Receipt | Canadian Depositary Receipt |
|---|---|---|
| Who it serves | US investors buying non-US companies in USD | Canadian investors buying mostly large U.S. names in CAD |
| Listing and currency | US exchanges, priced in USD | A Canadian exchange, priced in CAD |
| Currency exposure | Carried through — FX moves pass straight into the price | Hedged — most day-to-day USD/CAD swing removed |
| Ratio behaviour | Fixed ratio, set to keep price in a normal US range | Resets daily to keep approximate currency neutrality |
| Main embedded cost | Custody or service fees deducted from dividends | FX spread — up to about 0.60% a year for U.S. names, 0.80% for global |
| Issuer role | A depositary bank holds the underlying shares | CIBC is depositary and facilitates voting and some shareholder rights |
Which one to use
Reach for American Depositary Receipt when…
The ADR lens fits when you are looking at a non-US company from a US account and you want the foreign-currency exposure to remain part of the picture. Because the price formula divides the local share price — times the shares per ADR — by the FX rate, an ADR shows you the company and the currency together, which is the honest view if currency is part of what you are studying. It is also the relevant lens simply because that is often the only US-listed form a foreign company takes, though many large Canadian companies trade directly on US exchanges as ordinary shares rather than ADRs.
Reach for Canadian Depositary Receipt when…
The CDR lens fits when you are looking at a large U.S. company from a Canadian account and want to isolate the business from the currency. The daily ratio reset is built to hold approximate currency neutrality, so what moves is closer to the underlying stock alone, and the fractional interest lets an expensive U.S. share be examined in smaller CAD amounts without a U.S.-dollar account or a conversion. The trade-off is that the hedge is approximate and not free — it does not eliminate exchange-rate risk entirely.
The concrete mistake is assuming the two wrappers treat currency the same way. An investor holds an ADR, sees the home-market shares rise while the ADR does not follow, and blames the company — when the ADR formula divides by the FX rate, so a currency move alone can account for the gap. The mirror mistake is holding a CDR and expecting to capture a favourable USD move: the daily-reset hedge is designed to strip most of that out, and the embedded FX spread is charged whether or not the currency ever moves your way.
How Quintarthai uses them
Both wrapper types show up across the listings and company data in /app/, so a foreign name may appear as a US-listed ADR, a CAD-listed CDR, or an ordinary share depending on the venue you are looking at. Knowing which wrapper a quote refers to is what keeps a price comparison meaningful — this is background for reading the data, not a recommendation about any security.
