I hope you added before the big ruin-up, right?
What's your cost basis? The reason I ask:
While it's not a hard and fast rule, I try to organize my buys by moving in lock-step with the momentum being reflected. When momentum is screaming "Buy me!" I will usually place a smallish buy order, assuming the price will drop back when day traders cash out. If I'm wrong, as happens often enough, I let the smoke clear a bit, as in wait a few days. If things haven't simmered down, then I know I have no choice but to jump in now. Thus the value of having an exit strategy.
This is why I'm not buying more---5,000 units for me is enough. With eighteen horses in the stable, ALDW is up there in terms of portfolio percentage, along with NGL. But I need to view each pick in terms of how and/or what it contributes to my over-all success profile of the moment.
