No rhyme or reason. Copper prices down today, but what befuddles me is that this company is raking in cash, has no debt and all reports are glowing with expanded mining reports. I am assuming big money funds has this stock and it is riding down with commodities as a whole. They are being clumped in . I bought some more as I believe this is a diamond in the rough. Just needs for copper prices to rise and settle. Just ride out the storms. Sad but true.
