We finally have the classic syndrome that indicates an intermediate-term top. Upward momentum has stalled, as sentiment has remained elevated for several weeks. The combination of sideways prices on high bullish readings becomes very bearish when it has been sustained for a month or longer.
Here is the RSI and price picture (note declining trend in the momemtum indicator RSI since late August, and its resemblance to the topping pattern last spring):

Looking at the headlines, it is nice to see good news that results in a bump with no follow-through. We saw that in mid-September with QE Infinity, and last Friday with the jobs report. Rallies end on good news and declines end on bad news.
It would not be unusual to see another test of the highs, and for prices to linger at these elevated levels for another month or so, but the odds of a sharp decline are now elevated, and any further gains should be quickly erased.
