According to Brooke Thackray, Research Analyst at Horizons ETFs and the strategist behind Horizons Season Rotation ETF ($HAC- https://horizonsetfs.com/etf/hac), the market tends to bottom just before an election, starting in September into late October. He highlights that this is a mistaken belief that there’s anything predictable on or immediately after election day.
Brooke likes the idea of looking for overlapping patterns between election, non-election and even pandemic years. He believes that there are opportunities to invest into the market before the election in defensive sectors like consumer staples, which historically have done well this time of year.
