If you are holding for long, you can start buying and if you want to wait to see whether you get lucky in buying more in dips, then be my guest. It is being overly full of presumptuous to think the market cannot go down or change direction at any point in time. I am not very optimistic on the market at all right now, and when that time comes, maybe I will. Nevertheless, it is always everyone's choice to make and if you do not know what to look out for in making your decisions, you can as well just buy now.
