this is a no brainer.i would do A. sell all the stocks and keep the 12% gain.start building a new portfolio slowly between now till after elections.if possibe,you can hedge your new holdings if u think the market will go down by shorting the ftse nse index or buying treasury bills that way if the mkt goes down u can still end up being in the same position you are in today where net net u have a 12%+ gain.in future cut small losses before they become huge losses.when u enter a new position you should have plan of what price to sell for profit or when to exit if it goes down.

Always look at the CURRENT price & prospects going forward. The rest is history. There are no capital gains tax... so it's irrelevant as to past profits & losses...
