Dr. Bull can sternly correct me if I am ill-informed, but I believe the significance of each October has to do with where in the 4 year cycle we lie.

October 2024 would historically be when we would expect to see the Bull market begin.

October 2025 would historically be near the cycle top.

October 2026 would likely be near the depths of the bottom of the bear market, from which we would be expected to slowly chop sideways/higher for two years before the next halving in 2028.
