For someone like Armstrong who cannot get his prediction correct every 8.6 years,

Not a bond market peak

Not a stock market peak:

And changes his "predictions" when the time gets closer and it's obvious,

He gets even more tries at the weekly/monthly/yearly levels.

Oh, and he doesn't even keep track of the conditional predictions.  And therefore, guess what, he thinks he is ALWAYS right.

His whole BS based on the all-important 8.6 years cycle of ECM, and then he cannot even get anything right on the date?

Oh, and according to the younger Martin Armstrong, ECM was 10/7/2015, while according to the older Martin Armstrong, ECM was on 10/1/2015.  (See the link below for the two dates).

Now, go figure.  Should it be bond peak or stock peak?  Should it be 10/1/2015 or 10/7/2015?

If you guess it wrong from one of the two choices, it is ON YOU, because you are so stupid that you cannot understand his complicate models that produces TWO different dates, and TWO different predictions.

Just like how Armstrong explained, bond market "crashed" from the participation, not price.  Oh, didn't he just say that AFTER-THE-FACT?  Isn't that the very definition of HINDSIGHT?
