Investigating 101: S&P500 Then vs Now

So I saw this tweet this week and was shell shocked at the similarities - but it had me thinking... What actually is this timeframe?

Is that when the official bear market started? Or is that when it just made it look the most similar? Well - I decided to do my own digging and these are the results.

Not going to lie to ya - this is pretty accurate to this point in terms of pricing structure and patterns. The rise to the drops are all within weeks of each other over a two year period.

That is scary stuff, and not to mention that 11/13 bear markets had its biggest move down in the last 3rd of the year. We could be in for a rough few months.
