The Session

Risk-on held at 1.18 standard deviations above neutral, down 0.16 on the day and at the 79th one-year percentile. Bitcoin jumped 7.09% to 69,266, while the dollar index fell 0.82% to 98.83. VVIX dropped 6.3 to 86.5 and MOVE declined 3.7 to 71.3. Options implied a 0.54% expected move, or 42 points, into the 20 August expiry; one-month skew compressed 0.53 points to 3.62.

A VIX move back through 15, or an S&P 500 retreat from 7,707.98, would change the tone. Sessions that opened in the 15–20 band have stayed there on 82.9% of 1,692 observations. Core PCE and the GDP second estimate are due 26 August.
