What Kind of Bounce Can We Expect?

You are talking about a rule, the rule of the 50s for the S&P.
Today's markets are not based on rules but on expectations.
I would consider, besides, the mathematical approach of the 50s, other non-mathematical externalities and assessments to evaluate market behaviour.
For example, perspectives of consumers about the cost of living, and trends in how incomes are used.
