I should say that the "annualised %age" figure is capped at a LOSS of 100% - you can't lose more than your $$$, as per the discussion in the 2018 thread.
This early in the year of course, it means that if companies share prices declined at the same rate, the loss is capped at 100% in the annualised figure.
I'll update the rankings to be based off the CURRENT %age shortly.
