Direction Can Be Right and Calls Still Lose: Testing the July–August IV Crush方向对了，Call 仍可能亏：用盘面核对 7–8 月这次 IV crush

A mid-August note said the last month was a crowded dispersion unwind, not a normal earnings IV crush. TradingFlow Rank Symbols checks SPY, mega-caps, and NVDA on the August 14 session.一篇 8 月中旬的长帖认为，过去一个月不是普通的财报 IV crush，而是拥挤的 dispersion 反向收敛。TradingFlow Rank Symbols 用 8 月 14 日的 SPY、大型科技和 NVDA 核对这件事。
