Purely technically speaking I would say that you watch out for a technical correction. Another rise should be possible until around 27.50 which is the low of December 2006. But then take into account that this sharp rise is not from another world. It is -whatever the reason of the breakout of the more than 5 year old range might be- the end of an ABC-wave June 2011->November 2011->November 2013. So the time may be ripe for a correction with the possibility of an overextension to 27.50 as said above.
I will publish a chart of it for explanation.
