Non-technical events aside and considering the post-Oct periods of both charts, the current period has both lower highs and lower lows, while 2012 had only descending highs. The first trading day in 2012 enabled the break-out in that chart.
I offer this comparison to '11-'12 mainly as a contrarian view that the market might not retest lows, even 200. If we see a return to OB and book it from here, it might just keep going.
