You can note that there were two similar instances where inflation was getting higher during mid-term elections (1974 and 1980). In an inflationary environment, most likely the S&P bottoms when the inflation (CPI) has peaked. However, in 1980, the S&P went higher after mid-term elections despite inflation rising and having not peaked.
So the S&P can bottom anywhere from June to October (possibly at $3200- Fib lower level), then rally after mid-term elections. If post-mid-term election, the unemployment rate starts going up, it can lead to a recession in the upcoming years.
