How's this for a theory??, page-58

Macquarie were wrong by $10,000 in August 2016 when they made a statement in Bloomberg......$7-8,000 a ton by mid 2017......what was the price in mid 2017 ?? $16,000 a ton.....so I think any forecaster needs to own up and tell us how they got it so wrong....where was the error??

I also have their 30th May 2016 LITHIUM MARKET OUTLOOK ....."we are bullish lithium on an 18th month view, with an average price target of $8,250 for 2017"........They refer to Chinese prices , not Japan or S Korea....as in their graph.....
