How To Tell The Difference Between An Add-On And a Buy

Hi Pat, I've recently joined mission winners after being referred to it by a trader in a discord trading group, i really love your attitude and am absorbing all the information here like a sponge. I was wondering, what is the thought process behind if a stock is an add-on or a buy. If something is an add-on, then I am assuming you think the price will go higher, so why could it not be a buy as well? Is this related to risk and reward, maybe it's too risky to buy a stock if it's been trending for a while and has already broken multiple points of resistance, but if you have already been in the trade, then an add-on is worth the risk. I hope you enjoyed your thanksgiving! Kind regards, Torin
