Boeing nearly had me chanting USA- USA! like Unky Herb ( Simpsons reference) when it made a new high like a rocket without any resistance recently.
But...look at the volume coming out of that this month...month not quite over yet either.
There's a heap of big companies that if you zoom out you cant see a period anything like the vertical rise of the last five or so years.
I don't know why its just an observation. I read old literature on charting and you can see what happens every time to every vertical stock in history.
