I don't expect the next QE to happen before late 2024 at the earliest (just in time for the US elections -coincidentally-
).The inflation won't be stabilized around the 2% target until 2025...
To me it seems the stars are aligning for yet another spectacular bull run in 2+ years from now.
Although it is difficult to predict outcome of financial event with 100% accuracy, however I agree with your opinion that QE is possible by the end of 2024 which is coincidently election year in USA as well anticipated event of Bitcoin halving in mid 2024. Hence, these both important events can serve as significant factors potentially triggering uptrend in both Stocks and crypto currencies markets.
