We drew the parallel in NFTRH 362 using a weekly chart like this one. As it happens, the ‘quants' are on this theme as well. As B.I.G. points out, it's been one of the longest runs on record (1,326 days) without a 10% correction. Well it is here and it is remarkably similar to 2011's correction.
Blow the chart up by clicking it. You'll see a similar price pattern below the EMA 70, which is starting to turn down, similar MACD, over sold RSI and AROON down. A difference is that 2011 had big down volume bars and this one does not have capitulation type volumes yet.
Now, will history repeat? I am certainly open to it. But the very fact that it's been 1,326 days without a 10% correction is a negative, not a positive. Something about pressure buildups and the like.
