The TMX Group who run the Toronto Stock Exchange is to change with tradition and allow four letter company shortcodes (epics) for the first time.
The start date for this is the 1st November, and is designed to allow companies to link their code to their marketing.
The TMX group have sensibly allowed four letter ticker symbols for the first time. as it does allow a company to have a more meaningful ticker which is useful in their marketing.
Already SHOP (Shopify) and ONEX (Onex Group) are good examples. Onex was formerly known as OCX, which doesn’t identify the company at all!
This can lead to some obvious amusing symbols of course;
Placer Uranium Mining Portugal
is one example, and there will probably be many others once people put their minds to it.
