I am a bit concerned about the recent sharp drop in cobalt price,
look at this: https://tradingeconomics.com/commodity/cobalt

  
I am holding a relative big position in CLA, not as much as Phuket Guy unfortunately, but for my account it's sufficient.

This is my first message on this threat. I am reading HotCopper for many years and i am delighted at the knowledge of so many posters here, to take PG as one example for all others here. I am a none oz shareholder, so my foreign broker account does not allow to participate in the latest spp. I hold CLA from early days of 4 cents, adding up at different prices and i am happy with that so far. I don't sell any shares in short time, i am waiting for the long run!
A other poster showed us today a one year graph, which was not so ugly, as a found
one for recent months in 2018.

What do you think is the reason ?  Are some others here also concerned a little bit
from recent cobalt prices in connection to our loveable CLA ?
