Yamana Gold’s (AUY) stock has also underperformed the gold miners’ index (GDX) year-to-date by returning -6.6% as of April 17. AUY’s 4Q17 results disappointed, with the company reporting earnings far below analysts’ expectations. Its EPS (earnings per share) were -$0.20, below analysts’ estimate of $0.03. The major factor driving the loss was a $356 million non-cash impairment charge related to the remeasurement of its Gualcamayo mine and related expansion projects in Argentina. Investors are wary of Yamana’s inconsistent operational results.
