For five straight trading days, the price has been below the $120 mark and the trend line is distinctly downward. Iranian officials attribute that to the positive outcome of Iran’s talks with the Big Six. However, only the last day on the chart above, showing Monday’s price, came after the talks. The downward trend actually began a week earlier. The monthly average (below) is also off, but not by very much and not at all compared to any month other than last month.
