Normally i'd agree, but CXA - for reasons i don't know - seems to always be a sizable percentage of KNL's daily volume and this doesn't show up on most platforms. Take the 24/9 for instance, there was 1.1m traded on the ASX, 300k on top of that on CXA and i believe a further 350k on the German exchange (that night).
Today - so far - there's been 220k traded on the ASX, but an additional 95k traded on CXA. It seems that whatever is traded on the ASX, there's almost 30% (an average guess) on top of that traded on CXA.
I also think the tight register is finally about to pay off, and another complication. There simply isn't the volume of shears available to the market as there is in some other companies. CBA alone hold 10.78% of KNL. And don't get me started on Spinks and co. who also hold a sizable percentage of the company.
I think regular metrics can't be so easily applied given the above complications. But hey, give me a rising share price on 1m plus volume days any day of the week.
