I wait for 435-440 because I already have the shares i need in 455-460 area, and did a number of call and put back and forth to protect them.
435-440 is my next target where I will commit another significant portion of portfolio.
Will leave a small portion in case QQQ drops to 400
If QQQ drops below 400, and really crashed, well, I will get rid of all my long term bond at that point and all in QQQ.
Eveyone's sitution is different but as long as you have a strategy and stick to it, and manage your asset aoolcation, things will turn out to be ok. We are still in the long trend bull market and this is the opportunity to accumulate all the good stocks.
Do not let market noise to impact your action
