Weekend thread 3/11/2017 Melbourne cup tuesday, page-36

Howdy people hope everyone had a great day just wanted to ask something. I've noticed by reading through threads of shares I've invested and looked to invest in, that many of you picked up stocks just before or had been holding prior to them rocketing up. I'm fairly new to the share market but I'm just wondering what trends you look for to indicate these spikes. Knowledge is key so any advice would be greatly appreciated thankyou
