In this article I set out 5 ways to selectively filter down the 1,800 companies outside the top 300 into a cohort that's at least worthy of some further research. Given my previous article <a href="" target="_blank" data-event-type="click" data-event="link_click">(VIEW LINK)</a> highlighting that there are over 1800 companies outside the top 300 companies listed on the ASX how on earth does one go about narrowing down the field? At least into a cohort that are worth further analysis, let alone committing any capital to. Much like a Coober Pedy opal miner we need some tools to help us unearth some gems.
