Zhipu Plunges 40%: Kimi K3's 'Dimensional Strike' or Valuation Model Slippage Correction?

When a model drops 40% in two days, is your first thought that market sentiment has spiraled out of control, or that your risk management parameters are set wrong? On July 20, Zhipu (2513.HK) saw its HK shares plunge for two consecutive days, with a cumulative drop exceeding 40%, while MINIMAX (0100.HK) followed suit with a 10% decline. The market pointed the finger at Moonshot AI's newly released K3 model—a competitor claiming "8x improvement in long-context reasoning efficiency." But to quant traders, this looks more like a violent liquidation of "factor exposure" rather than simple scapegoating.
