Let's see if Intel's chart can give us a clue to what Intel's earning's might be or how to trade INTC after it's earnings are released.
First thing to notice is yesterday doji right at resistance, this is a bearish candle. The 20.66 level provided resistance perviously and moved Intel down to 19.50, it also formed a doji candle around the 20.66 level. There is also longer-term resistance above the 20.66 level that can be seen on the weekly chart.
While there is resistance at 20.66 there is strong support at 19.50 but be careful of the gap that has not been filled at 17.50. If Intel misses their earnings, it could try to fill that gap.
Intel doesn't report till after the market is closed but these should be key levels to watch after Intel announces earnings. But more importantly watch INTC at 3:56 when the big guys get the earnings report first.
