With the Greece uncertanty the S&P500 will be under increased pressue to the downside. In my opinion traders in the US really do not have a reason to buy stocks based on a bailout of Greece. From what i am hearing the bailout might not happen because there is not a EMU bailout clause.
The SPY(daily) chart on the left shows a clear uptrend pierced at the 111.70 level. On a 10 minute chart, there is a clear pennant forming, it is unclear whether it will break to the upside or downside. What we do know is the long trap could be developing, the long wicks of the last few candles indicates a tug a war between the bulls and bears.
Volume is confirming the war, you can see the volume steadily down trending from may 2009 until it spikes mid Jan early Feb 2010. The PPT is hard at work, though i feel we are back in the same position we were last year, nothing can really stop the "correction". Longs might get a bit of a bounce to close the small gap highlighted in Blue, but a sharp reaction to the downside from that point is probable.
