I have a very selective filters that returns me 6 darwins atm.
Both ERQ and RAT are returned by the filter.
They surely are interesting darwins.
BUT... the problem is another.
You will always find darwins on highs.
Imagine you bought RAT on the last high in August 2021, you would face 3 years of stagnation, are you ready for it?
ERQ has avery long trackrecord but there were also a couple of episodes of revenge trading that are not so easy to spot from the return chart and the darwin has problems of capacity and divergence.
Recent return is always attractive but mostly never predictive.
