Just last week the two stocks were crushed after Fairmount Santrol Holdings $FMSA said they would join its rivals and open a new sand mine in the Permian basin. The concern is all this expansion could lead to overcapacity when the mines come online over coming months. Haliburton $HAL also warned in its earnings report that fracking were “putting ion the breaks”
That was a big hit after such a decline and then a miss in that environment was tough. Though they are making money now but as you said stock price got way head of itself.
