Why is it so straight?
Is this a result of some fundamental underlying economic laws?
Or is the Federal Reverse using its powers to maintain a very specific level of long term economic growth?
There are 6 instances of it bouncing off the top of the channel and none breaking through over 10 years.
The last time it hit the top was September 1st where there was a sudden drop of ~35% without any obvious trigger other than it hit the top of this channel it hasn't broken through in 10 years.
I obviously have a high possibility of being wrong, but can you think of any good reason for a sudden drop like that in September?
