Who's left to buy? And if so for how much longer?As stated in my previous idea I'm of the belief big tech is close to topping out, When I view these charts I can see cases for all to be nearing a top (yes they can go higher) but It won't matter much if the overall trend is close to terminating. Ask yourself logically who is actually left to buy here and happy about it? and if so how much longer can they do it for?, The potential downside risk on all of these trumps the short term gains you might make.
