September - How low can we go?

Chart shows S&P 500 (Stocks), Bitcoin(yellow) and Ethereum(white), which appear to be somewhat correlated in terms of market direction.

Red blocks highlight September (roughly) every year for the past few years.

There more than not dips or downward movement there or thereafter

I am keen to see if there's continued adverse effects for the remainder of September...

Not financial advice at all. Just a noob trying to find their way round these crazy markets.
