Price stopped fall at the 0.618 retracement ~4321 SPX and held for an intraday double bottom ~4310. Holds above the previous Friday's finish after a mad V rally.
Stonks remain in a downtrend but this countertrend move may be only halfway up the flagpole. C wave ought to carry index to the upper trendline of falling channel, another 100 pips above.
Confirm Monday. Price action 10/13 was indeed spooky, from where came this mad gap up, but it vaporized in under an hour and the rest of session was spent testing the 20 DMA.
If you short it here you may well be selling at the bottom, be ware! GLTA
