Here is some DD on how trading works to clear up the false information that this a US company. The addition of the letter F (5th letter) at the end indicates it is a foreign stock and not located in the US. Proof once again this is not a Custodian pjay because US Custodian laws do not apply to foreign tickers
So we can put that Yahoo BS to rest now.
What is an F share? While some US investors can trade directly in a foreign company’s local market, many US investors prefer to see quotes in US dollars during their regular trading hours. To provide this access and to facilitate trade reporting, broker-dealers create trading symbols, or tickers, of foreign securities in the US. These tickers are 5 letters long and end with the letter “F”. As such, they are traditionally called F shares. More than 2,000 companies with primary listings on more than 30 global markets, such as London, Frankfurt, Paris, Madrid, Milan, Toronto and Tokyo, have an F share on OTC Markets.
