A lot of those figures are incorrect I just checked the ones on my watchlist and found many of them performing better than that article. Looks like the data has been cherry picked to suit his view.
The most glaring error was AGY which is up 100% on last 12 months or we could cherry pick the data and claim a 525% gain over the 7 months to the 27/05 given it peaked during trading that day at 10.5. CAD is up 25% article says -33% GXY is -5% vs -30% claimed, ORE is -10% vs -28% , CHK - 30% vs -56% claimed. The only one I follow that was mostly accurate was PLS but we could cherry pick that and claim an 800% rise in share price over 2 years. GXY , AGY and others up well over 1000% over last 2 years.
