Just for the heck of it and to relieve the boredom I ran the slide rule over price movements of coal stocks on an old watch list.
compare STOCK CODE M.CAP 52 WEEK HIGH CURRENT
RES 81mill 80c 33c
COK 188 48 19
CCC 39 31 0.08
CLR 76 $2.35 54
WAL 6 53 11
CPL 435 $2.00 66
BND 169 $2.29 31
ZYL 63 27 13
By no means exhaustive but encouraging none the less
Cheers Chooky
