Here's a video I made a while back about the research button on Etoro and how to use it. It's not the most comprehensive video :) but I still thought I'd post it as it does explain a few things. The research button basically gives you access to some industry-analysis. What are the bank's analysts saying about this asset? Are the hedge fund managers buying this asset or getting off their books? What are the people inside the company itself doing with their shares in this company - are they buying more or selling them?
This information can give you a better idea of how the industry currently views the asset - whether there's confidence in it or not. To be honest, I don't pay that much attention to these statistics, especially now, as all I'm doing is Copy Trading, which means I've set my account to automatically copy the trades of more experienced traders (Basically, I don't need to do a thing - they do all of this analysis for me and then work out which assets to buy or sell... It's great. And free.) Here's the video anyhow :)
