<<It's practically a mortal lock that you'll see it next year>>.
If the S&P 500 is down 20% from here, there is essentially no chance that Pfe will be at 20 next year, unless something very positive, very important and very unexpected occurs to Pfe.
Do you think it's a coincidence that at this writing the S&P is down just over 1%, as is Pfe? Last week, you saw the opposite. Continuing to blind yourself to the obvious, logical correlation will only hurt you further in the market.
