This has to be a first:

Now Hong Kong’s pro-democracy supporters are wielding a new protest weapon: their stock-market trading accounts. To show support for Jimmy Lai, the publisher who was arrested Monday under the city’s new national security law, Hong Kongers have been buying shares of his media network Next Digital Ltd. The result has been a more than 1,000% gain in two days that propelled the stock to a six-year high.

I’m not sure how effective this will be, but I applaud the spirit of these advocates of freedom for Hong Kong.
