I have followed the trading trend between the 2 stocks.
Until yesterday morning and today.....GFSA3 has followed GFA
Last 2 days at morning openings ...GFSA3 has opened about $0.20 down from previous close and GFA has followed....what is going on?
i track the ADR versus its implied parity value using the realtime FX and local share pricing. it is a better measure of where ADR investors are in terms of the local shares and currency. i am not sure how significant the correlation is between the ADR and local shares b/c most ADR investors aren't watching the local shares.
