A split changes the held quantity and requires split-adjusted historical price data; tasks 32, 38 and 36 are involved in this. Tasks 31 and 43 read the dividends. Course of a split The daily task 30 reads one or more split calendars. A calendar names a split with ticker symbol, company name and usually also the exchange or the country of the listing. GT assigns it to one of its own securities only if the ticker symbol matches, the listing fits the stock exchange of the security and the company name is sufficiently similar. The check of the listing is necessary because depositary receipts such as the Canadian CDRs often carry the ticker symbol of the underlying stock but split independently of it. On 16 October 2026, for example, a split calendar reported splits of the CDRs of Advanced Micro Devices and CrowdStrike under the ticker symbols AMD and CRWD; the stocks themselves were not affected.Hugoen
