As per the Reuters headline, an impressive rally out of the 1650 - 1670 range, settling eventually around 1675.
Reuters puts it down to fiscal cliff hopes...
I haven't been watching the markets as closely as usual over Crimbo period, but my initial reaction was not the same as the news media. Obama said the usual stuff ... "deal in sight"... "but not done yet". To me... the fiscal cliff news was plainly BAD. That was my initial take anyway.
Interesting level around 1680 on the upside... break above there and I'm wondering if price might rapidly "slipstream" clean through towards 1700, in similar fashion to the sharp declines of Dec 18.
