VIX volatility index falls 20% intraday to 16.66

A single-session collapse of this size in the VIX signals that demand for downside protection unwound quickly rather than that conditions became calmer gradually, which matters for anyone holding options-linked or volatility-sensitive exposure. The speed is the story: such sharp drops in the fear gauge often reflect positioning unwinds as much as genuine improvement in the outlook. Whether the VIX holds near these levels or retraces is the open question, and it bears watching alongside whether the drop in expected S&P 500 volatility persists beyond the session.
