For the ones that are bigger than the CV value, they will keep their current CV value. More thinking is needed about what to do with those.
I've got a couple like that that were purchased in 2007 at the high for them and whilst they're now above $2000, like the $2200-2400 range, I can't sell them back down to $2000 without taking a loss, which I'd rather not do. If they get up to the point where I can sell off a couple hundred I'll probably do that. Meanwhile, as they're all dividend payers, I'll take the dividends for now!
In pondering Praveen's system I find that it falls in the family of "core position" systems where one takes a core value, $2000, for example and then trades around that with future sales and/or purchases.
Best,
