Bubbleicious indices keep marching up on regurgitation of same news... where it stops nobody knows.
Some ideas though:
1) Looks to be painting some sort of ending diagonal. I say this because to my eye it looks like the moves upward look like AB=CD patterns (green boxes) and ending diagonals are impulse waves of 3-3-3-3-3 as opposed to the typical 5-3-5-3-5.
2) Accumulation is completely flat since the demand zone at 3150. The buying fervor on low volume suggests retail buyers piling in on news of China deal, while smart money has been out since 3150.
3) Deep crab pattern in play w/ invalidation at a close above 3245 and confirmation of a daily close below 3212
4) 1/1 Gann line is critical support for current diagonal. If broken, there's little support to slow down a steep descent to the 1/2 line. It's possible the day after X-mas could be similar to last year... a complete and violent reversal going the opposite direction.
5) That said... I don't see this thing dumping prior to Xmas and until the diagonal breaks, there's little reason for bears to get excited.
6) VIX has been basing upwards as has GOLD since the china news. Daily PVSPX put volume is spiking as well, though this is not usually an indicator for a top.
Stay vigilant bears.
