While Buy and Hold performed better, it is pretty impressive that a strategy documented almost 150 years ago had a 91% hit rate.
The strategy also identified the (near) peaks of major crashes including 1929, 1999, 2007 and 2020.
Two key learnings:
1. Buy and Holding (while boring) is a fantastic strategy
2. Market cycles are repetitive. While the times, technology, markets and oversight have changed massively in 150 years; market cycles haven’t.
Human nature never changes.
I didn't publish it in the end, because his strategy is just issuing a BUY/SELL signals in certain years, per the image.
The next signal is in 2023 to "Buy".
NB: "buy & hold" outperforms Tritch's strategy in long-run, but Tritch's avoids the big drawdowns.
