I'm in the process of deciding whether I should commence subscribing to Stockopedia. There are many things that I like about the platform but much to my disappointment I noted that the S&P 500 index significantly outperformed Stockopedia's stocks whose ranking was over 90 (between 2015 and 2019).
This seems to contradict everything Stockopedia claims it can achieve and is troublesome given the S&P500 represents the biggest bourse in the world.
Can anyone explain this poor performance? Does this mean the Stockopedia works well in most countries but the US?
