After the July 1st protests plus a bunch of arrests the HK market is up 2.85%. HK is now up almost 6% since 5/21 when the announcement came out about the new security laws. Since end of May HK markets are up over 11% and have way outperformed Taipei, Tokyo and Soeul during the same period. All things equal the view of investors is that the protests will peter out and the city will go its old goals of making money.
Problem is, with Hong Kong losing any shred of autonomy, there's little reason now to treat Hong Kong any differently than Shanghai when it comes to financial matters. I've avoided investing in Chinese and Russian companies not because of disdain for autocrats per se, but because I can't trust the reported financials.
Also, I see you cherry-picked your period for comparison.
YTD, Hong Kong is doing worse than not only the three markets you've mentioned but also Shanghai.
