There are much, much better ones: 1) Philosophical Economics' stock/bond/cash preference model: http://www.philosophicaleconomics.com/2013/12/the-single-greatest-predictor-of-future-stock-market-returns/ http://www.philosophicaleconomics.com/2013/12/the-single-gre... https://financial-charts.effingapp.com/ https://financial-charts.effingapp.com/ 2) John Hussmann's non-financial market cap to gross value added: https://www.hussmanfunds.com/category/comment/ https://www.hussmanfunds.com/category/comment/ https://www.hussmanfunds.com/comment/mc210715/ https://www.hussmanfunds.com/comment/mc210715/ But as the sibling comment and all the sources above say, those do not predict the path, only the destination (which is a decade or more in the future). It would be completely consistent with such macro valuation models if, for example, the general prices doubled or even quadrupled over the next year or two, why not. Stay safe out there :)
