The CBOE Volatility Index gapped up 5.23% at the July 20 open, reaching 18.90 before pulling back to close at 17.96. The session high of 18.94 marked the day's peak, while the low of 17.77 represented a 1.17-point intraday range.

The VIX gapped up 5.23% to open at 18.90 on July 20 before retreating to close at 17.96, erasing the entire opening move.
The opening gap of 5.23% was the largest single-session gap for the VIX in recent trading, according to exchange data. The index opened at 18.90, touched a high of 18.94, and fell to a low of 17.77 before settling at 17.96.
The intraday range of 1.17 points between the 18.94 high and 17.77 low reflected a session of elevated volatility for the volatility index itself. The close at 17.96 matched the prior session's level, meaning the VIX round-tripped the entire opening gap.
The failed breakout above 18.00 keeps the VIX within its recent range. A sustained move above 19 would signal rising hedging demand, while a break below 17 would suggest waning concern among equity investors.
