Japan's total stock-market capitalization as a percentage of GDP - the per-country version of the so-called Buffett indicator. Because listed-market depth differs hugely across countries, the level only means something against Japan's own history: well above its historical range suggests a rich market, well below suggests a cheap one. Annual World Bank data, so it moves slowly - which is exactly why it anchors the valuation pillar of the tailwinds score rather than trying to time anything.
