China's stock market is inextricably tied to politics.
China frequently confounds stock market prognosticators because it has a penchant for straying markedly from other broad global indexes year-by-year over the decades - even from emerging markets. It's hit or miss.
If some stock categories get too hot-and-pricey, mass supply is created via stock offerings to tap that cheap money - and, when overdone, drives it all down.
In history, the evidence is overwhelming: Stock market bottoms happen, and then stocks jolt upwards while the economy keeps getting worse - sometimes by a lot and for a long time.
In the world I've known most of my life, old stories quickly lose their power over capital markets and get replaced by new surprises. That which everyone fixates on gets priced into the stock market quickly and can't drag on.
Buying only what you know can end in disaster. Just think about Enron's employees and business partners, the 'locals' who bought lots of its stock because they thought they were in the know.
