The political turmoil in Iran turned the mood from positive to negative going into the week and that seems to be coloring people's interpretation of the earnings. My sense with Apple is that in the current mood of the market, no news would have been good enough to support the stock.
So far the corporate profit outlook remains positive. I don't hear a lot of companies saying they're going to reduce their profit forecasts because of interest-rate concerns, and that's a positive for the market.
