Dual Listing
When the same company's shares trade on two stock exchanges at once, such as both the Toronto Stock Exchange and the New York Stock Exchange.
What it is
A dual listing means one company has its shares listed and traded on two separate exchanges, often in two different countries and currencies. The listings represent the same underlying ownership, so a share is a share regardless of where it trades. Many large Canadian companies are dual-listed on the TSX (in CAD) and the NYSE or Nasdaq (in USD).
Why it matters
Dual listings widen a company's investor base and let people buy in their home currency and time zone. The catch is that the two prices can briefly drift apart after currency conversion, and liquidity, dividends, and tax treatment can differ by listing, so the cheaper-looking quote is not always the better buy once FX and fees are included.
How it's calculated
A dual listing is a corporate structure, not a calculated number; you can compare the two listings by converting one price to the other's currency at the current exchange rate.
