Hong Kong's AI model twin titans plunge over 13% as short-selling hits fresh high

Hong Kong-listed AI large-model stocks — the sector's "twin titans" — plunged more than 13% on August 19, with short-selling data hitting a fresh stage high.

The report shows both stocks fell by more than 13%, signaling a sharp rise in bearish pressure on the AI model sector.

Short interest reaching new highs means the battle between bulls and bears over AI model companies has intensified significantly.

AI concept stocks in Hong Kong tend to move violently, as the tug-of-war between valuation and earnings expectations amplifies single-day swings.

Why it matters: how AI model companies perform in secondary markets is one of the most direct barometers of market confidence in AI commercialization.

Watch next: whether short-selling data keeps climbing, the two companies' upcoming results and product progress, and whether the sector stabilizes.
