I have a serious question since you seem to work in finance. How come all this is expected of just China? Wall Street shoots a fire hydrant of money at American companies - no questions asked - while Chinese companies with great performance purely on finance's favoured profitability metric get hammered.
Why isn't the US president expected to announce comprehensive reforms as part of a plenum?
Because the S&P 500 Index is up ~11% CAGR in the past 10 years and 9.6% CAGR in the past 20 years. The economic/social/political rot in the US has not impacted financial performance of Fortune 500 companies. Therefore investors are happy to buy more stocks. Investing in the S&P 500 is almost religious (go read the finance bloggers like Morgan Housel etc) among the investor class in the US.
Not "announcing comprehensive reforms" is the feature, not bug, of the American capital markets.
Now of course that could change when the chicken comes home to roost and the US implodes and we unravel. But the two most important things in investing/finance:
1) The market can stay irrational longer than you can stay solvent;
2) Being early is no different than being wrong.
So while I understand why everyone here wants to experience the mental orgasms from imagining China becoming #1, it is important to live in the present and not in the potential future.
Before anyone tells me that only the top quintile or so in the US owns equity assets - like yes, do you think this is any different than in China? Probably only 10% of people in China care about the stock market - but you, being an English speaker with access to SDF - with free time to opine on issues discussed here, are in the top quartile if not top decile of society. (Accessing SDF in China requires a VPN, which costs over 100 USD/yr).
As well, consumption is largely a rich people business - The top quintile of Americans contributed to about 45% of Personal Consumption Expenditures; whereas the top 1/3 of Chinese contribute to about 50% of Chinese consumption (retail sales as a proxy). Guess what, pissing off the rich people by enacting necessary reforms isn't conducive to them investing/consuming.
More important is where China's industrial upgrading is. How SOEs and companies in critical sectors like semiconductors and advanced manufacturing are doing.
I've made this point many times, but the good parts of the economy aren't big enough yet to offset the bad parts. Personally know someone senior at Huawei who just upgraded to an 800k rmb car this year - clearly feeling great (rightfully so) about their future prospects. But someone of a similar age at Vanke or Country Garden would not feel the same.
