Positive Comparison to Sconi Greenvale, page-40

Only just started looking at this stock today - not invested yet. 

What's the consensus on the Nickel price? Been trending down last 6 months or so. I'm looking at the Corporate Presentation dated 27th Sep 2018 - pg 7 theirs an graph of the Nickel metal price. The graph points out that when Nickel corrects it does so quickly but it falls at a similar pace at the points it references. Do they have someone way to take advantage of this sharp increase/decrease.

Hope I don't come across as negative just haven't had much to do with nickel in the past and curious. 

Thanks
