APX Charts, page-1129

IMO there is no real right or wrong answer. Eventually APX will find a valuation where the market is happy with and that will be it's base. With high volatility moves like this it should enter a low volatility environment for a little while meaning it will trade sideways.
So there is plenty of time to add more if you need to. Much has been factored in but conservatively just wait for the volatility to be sucked out of the market. Obviously external factors like Wall Street could add to volatility but as I said there is no real right or wrong answer - managing risk requires planning and how much you are willing to risk and time frames, personal financial situation etc. Making peace with losses quickly and moving on is an imperative trait to have but again no real right or wrong answer.
