Look across the sector and number of others down today with similar % losses. CRK, NFX, MTDR, SM, WLL, BBG, NBR. These are just a few and they are ALL down some 4-5+ % for the day. Looks like the group is getting hammered and maybe tax loss selling and just rotation, but whatever is the reason it will probably continue a few more days is my guess. Would wait to do any long position or addition within this group.
