I didn't click on the link. But if you are referring to the 4-year cycle pattern, that's very familiar. Did you really find it yourself?

Anyway, what happened in the past may or may not happen again. It is not in any way a guarantee that it will happen again. If it happened once, twice, thrice, that still doesn't assure you that it will happen again. So I wouldn't go all-in on that.

Perhaps the only thing that I'd like to believe as a guarantee is that better days will come. Whether it will follow the 4-year cycle pattern or not, it doesn't matter. What matters is that we will make another ATH sooner or later. That's something I can bet all-in.
