Looking at the individual ratings: - Household Debt: 5.5 / 10 - Market Overvaluation: 9.1/10 - Market Volatility: 0.3/10 - Public Debt: 3.7/10 --> SUM = 18.6/40 or 46.5%
Also I noted: Drawing a linear trend line through the "Market Overvaluation" diagram, does make it look a lot better though. One could argue that people get used to certain levels, hence a growing trend over time.
Taking only these factors into account, it does not look like the market is gonna crash soon. In my opinion it's likely going to be caused by another factor not listed here ;)
