Agreed, it hard to tell what will happen post-split. Have a small mining company that expected at least 40% haircut, but it is still holding steady.
If you aren't sure, buy half now and see how things go post-split. If it drops 'YEAH', if not and price holds then you are only out an extra commission. The only way you might lose is if it rockets afterward, and if that happens lock in your profits.
