I predict he won't liquidate today or any other day as he's been saying for ages they'll come right and thinks the pref shares are worth the full $1.00, LOL and there's no saying he bought at 9 or 10 cents that's pure conjecture.
I conceed if he did buy at 9 cents and sold today there is a possibility he could have "theoretically" doubled his money, but I think you're very premature congratulating him seeing as you're not aware of when he bought and at what price and if he's sold, don't you ?
Best to wait till 31 August before congratulating anyone wouldn't you say ?
