Keep the big picture in mind if holding for the long term.
The company conitnues to post important milestones, ticking the boxes one by one and Richards Bay Coal Spot price is 118 US Dollars (Bloombergs). So coal prices have not fallen away like some other comodities have this week. Penumbra announcement soon along with Botswana. If you like the story there is no need to panic and sell out on what might be the lows.
Just my view of CCC.
