US Central Command announced early Thursday June 11 that it had completed its strikes against Iranian military targets; Tehran retaliated with attacks on Gulf countries Thursday. Equity futures rose on the completion (S&P +0.72%, Nasdaq-100 +1.1%, Dow +0.64%) and oil pared an earlier ~2% gain back toward $91 on hopes negotiations could resume. CNBC reported investors now bracing for a "long grind" - the escalation dimming hopes of an early end to hostilities.
