Nah, I took my money off the table long ago and am playing with house money. Li's money. Your money. As to lost opportunity cost, that is measured conservatively against treasuries (zilch). That in mind, might as well keep it in LQMT at a 7 cent profit and the chance of another 40 cent spike. I sold ten percent last time that happened just to say I pocketed a profit. All pure profit. Also as to lost opportunity cost, that was already calculated in anyway, along with taxes & commissions, when determining how much to sell to get to a zero cost basis all those years ago.
It is a little more involved than you have assumed, to do it right.
