Any one have any idea what Credit Suiss is doing? I held SGH shares before which got smashed, and they had the same announcements of becoming substantial holder by Credit suiss, and their main purpose was to buy enough shares so they can lend them out to clients who wants to short SGH. Gut feel is that GMA might become a short target. My key dates to watch is 1/4/2018, Genworth US is doing a merger with a Chinese company... the decission is postponed till then by the US govt. Anyone has any insight into whether that’s good or bad for the Aus subsidiary?
