Here are the charts for AAPL. The market has priced in a range of 125-137 for post ER move. Although the price of AAPL dipped below the 125 level in after hour trading, but this level could remain in play to close out all the strangle option players. The daily chart highlights the potential levels for support, and they are all in the proximity of the Fibonacci retracement zone levels, i.e. 38.2, 61.8 and the 50 (which is not a Fibonacci ratio).
