STRK surged nearly 60% in a day—its price is 2 yuan and 1.5 jiao, and it’s sitting at the very top of the gainers list.

The market cap isn’t small: more than $300 million. Yet in a single day, trading volume is only around 1.7 million. People willing to switch hands at this level are extremely rare. Liquidity is thin—any slightly larger order can push the price straight up. I’ve seen this type of move a few times: when it’s rising, it’s gratifyingly fast; but when it truly comes time to unload, there might not be buyers left to take the bags.

Tonight’s volume—whether it expands or retracts—will basically determine how far this leg of the move can go.
