Chris, in short, i am expecting higher to come this summer, but probably not a fresh high over 2007 level. This whole move since October 2007 is corrective and we still have a final leg up before it completes the 'B' wave, (well, my reckoning anyway), there are a couple of different ways to label it, but it might see us well into late summer/autumn, hell, even into 2013 before the death spiral of wave 'C' back down to new lows...
Right now, my thinking is that we are in a complex corrective wave, of which A is finished and to repost my chart from earlier (below) i actually think tonight sees us end wave B too. That leaves us free to weave our way back down to a new low (12,700 area) before starting a more orderly climb back up.
Of course these are just my own workings and thus an opinion.
