This is exactly what is was looking at. Another common factor is prices are bumping upper band of the channel, added to the seasonality factor this makes the correlation with 2011 more likely. Yet, harmony and synchronization with other markets is important factor to consider, IWM seems to be bumping too but QQQ and XLF are far from it. Although it is not a necessity before a correction i am more worried about the strength of financial sector in particular. I will be looking closely to those elements to take good decisions during this summer. Good luck and thanks for sharing.
