I often say that you can find a blow-off bottom (BOB) on every chart frequency from minute to monthly - here are some monthly charts proving the contention.
These are all past of course - I've gone through a number of charts and the only one I could find that is current is this one -
And, of course, this is not an invitation to speculate in the stock market - as always do your own due dilligence. More importantly get several hundred charts, set up a two-year monthly view and see how many BOBs you can identify and then make note of how many BOBs failed. It might be the most important thing you do (stock market wise) this month.
