Welcome AoB!
It really doesn't matter over the long term. Biggest mistake most new AIMers make is waiting. Been there, done do that! (or didn't).
Rememebr the original Lichello model (10, 8, 7, 5, 4) never went higher than the initial purchase. It is not 'BuynHold'.
That's not to say that one should intentionally buy in at a high either. Most recently, I've been using the W%r oversold indicator to signal an initial buy in on issues I've been tracking / prospecting. Time will tell if this is an effective risk avoidance strategy. Of course I will always buy more if AIM tells me to. That's why we AIM high and keep some powder dry!
