While I see two cyclical events in the 80s and 90s, then major wierdness in 2001, I’m not so sure I see a cyclical pattern here that I can assume will continue perpetually.
Trying to predict the bottom of something that isn’t consistently cyclical is a bit of a challenge, methinks.
Look at Japan for the last 13 years, for example, after their last crash. Maybe we will see more stability after the coming bubble deflation, and there won’t be a stark “bottom.”
Maybe SD data is more cyclical, if one looks back more than two cycles, but I have only seen two cycles plotted.
