$Global Mofy AI(GMM.US) surged +147% in a single day, with trading volume expanding to two and a half times its usual level. Scouring through the announcements revealed nothing—it just hit a new all-time low on 7/8. This is a classic case of an oversold micro-cap being ignited by capital, with the next day's news already mentioning a post-market pullback.

$Jiuzi(JZXN.US) +85% at least has a story: the company officially announced its intention to sign a cooperation agreement for an AI intelligent imaging platform, with initial cooperation expected to generate about $1.0M in profit. Note the wording—the agreement hasn't been formally signed yet. A $1M profit expectation corresponds to a near-doubling in market cap elasticity in one day. The leverage in these low-float China concept small-cap stocks lies entirely in sentiment.

Both belong to that category of erratic moves with extremely poor sustainability: no fundamental anchor, driven by small float. The capital chasing in wants speed, not logic.
