Why does the market keep pumping on minor Iran peace deal rumors when knowing nuclear talks, the overarching issue, have completely stalled?

The market pumped yet again this morning on supposed peace deal progress, this time on rumors of oil sanctions relief for Iran. Good for a 1-1.5% pump from the overnight low. The market has pumped more times than anyone can count on peace talk hopes since April 1. Yet this entire time, America and Iran have not gotten any closer on resolving the nuclear issue, the overarching issue behind this conflict. About an hour ago, Iran even blatantly stated they will not trade nuclear rights for peace, as they've been saying the entire past 1.5 months. This one line should've single-handedly ended peace talk hopes so many times. It's blatantly obvious these guys are too far apart on peace terms. America wants the uranium, Iran doesn't want to give it up. You can't meet in the middle and give up half - there's no room for compromise. What are they even 'negotiating' about at this point? A little bit of sanctions relief rumor here, an iranian oil vessel passes the bloackade rumor there, nothing resolves the nuclear issue. Why do both sides keep pretending to negotiate on tertiary issues and continuing the ruse? But whoever is driving the market keeps allowing it to pump on 'peace hopes' knowing full well the nuclear issue is at a complete standstill.
