Look at S&P 500 indexes (Ticker Symbol SPY) date 2007-11-01, if I would follow your "pattern", I might be under the water for 4.5 years !!!!!! It went all the way down and recovers on 2013-02-19. Dont anyhow say "pattern" when it is clearly not a "pattern" that has repeated itself for over "100 years" lol.
