The chart below shows the whole story, with numerous reversal signals highlighted.
Resistance was set at $32.25 since early June and has stayed under that level until early October. On earnings day, the stock's price gapped higher, following the indicated breakout. At the same time, a volume spike was accompanied by the relative strength index's move into overbought range. This is the first such move in the past six months.
This is a lot of reversal signaling, so we looked at a potential trade of buying the November 35 put option at Wednesday's close. That put closed at an ask price of 0.81. With trading fees for a single contract, this will cost $90. A modest decline in shares of GM will move this long put option into profitable range.
