Options flow sentiment

Based on end-of-day 30 July, yesterday’s positioning and not today’s price action.

• Single-name flow: the cleanest opening interest sat on the call side, in long-dated in-the-money strikes on the session’s winners, which is the shape of stock replacement rather than fresh directional risk. Put premium was larger in aggregate but mostly deep in-the-money and printed at mid, and in our view that reads as rolling and financing rather than bought protection.
• Sector and ETF flow: long-dated call demand in index and country ETFs sat alongside dated downside in the semiconductor and credit ETFs, with nearer-dated premium sold against it. The pattern may suggest protection being bought at the long end and funded at the front.

Volatility surface – 31 July 2026, approx. 06:00 CET

VIX term structure

• VIX spot 17.09 (-17.28%)
• VIX1D 14.14 (-27.30%) · VIX9D 14.85 (-27.13%), both now well below the 30-day
• VIX3M 19.50 (-9.30%) · VIX6M 21.61 (-6.29%) · VIX1Y 23.12 (-4.03%), an upward slope that steepens through the long end

• Second-month VIX futures 19.57 (-0.55%), front-to-second ratio at 0.950, deeper contango than yesterday’s 0.980

Skew and correlation

• CBOE SKEW 139.90 (+0.25%), essentially unchanged and still far above the 100 to 120 neutral zone
• COR3M 10.20 (-21.48%), the 3-month implied correlation across S&P 500 constituents

What the market is pricing

• In our view the market removed premium for the first time this week. Yesterday’s reading for next Friday’s expiry was 171 points with seven sessions remaining. Flat volatility and the passage of time alone would leave about 158 points today, and index options are pricing 143 points (1.91%). Both figures are derived from at-the-money option-implied pricing rather than a forecast. Three consecutive sessions of premium building reversed in one. Options carry a high risk of rapid loss and are not suitable for every investor.
• The near-dated range has compressed hard. Index options price roughly 50 points (0.68%) into today’s expiry, and VIX1D at 14.14 now sits 2.95 points below the 30-day VIX after a week spent above it. That gap may indicate participants treat this week’s macro and earnings cluster as behind them.
• Correlation read. COR3M at 10.20 after a 21.48% one-day fall, alongside DSPX at 42.89, is consistent with a market pricing calm at the index level and movement at the single-name level at the same time. See Saxo pricing for costs and applicable charges.
• The level reset, the shape did not. SKEW closed at 139.90, up 0.25%, while VIX fell 17.28%, so the relative price of downside strikes against at-the-money is where it was during the selloff. Bond volatility did not join the reset, with MOVE up 3.93% to 77.09.

An index that moved without its members

Three-month implied correlation across S&P 500 constituents fell 21.48% to 10.20, while the dispersion index held near 42.89. Those two figures describe the same condition from opposite ends: large expected moves in individual companies, small expected moves in the index that holds them.

Thursday delivered exactly that. Microsoft rose 15.5% and Meta fell 7.95% in the same session, technology gained 5.50% while communication services lost 2.68%, and the equal-weighted index finished lower while the cap-weighted version gained 1.66%.

For anyone positioning in options the distinction matters, because index volatility and single-stock volatility stopped moving together. VIX fell 17.28%, yet the Nasdaq 100 volatility index widened its ratio to VIX by 8.00% to 1.61. In our view that combination may argue that what is left of this week’s risk sits at the single-name level rather than in the index. Options carry a high risk of rapid loss and are not suitable for every investor. See Saxo pricing for costs and applicable charges.

Today’s catalysts

Bank of Japan Governor Ueda’s press conference has already run in Tokyo. The US Q2 employment cost index lands at 14:30 CET, the July Chicago PMI at 15:45 CET, and the final July University of Michigan sentiment reading at 16:00 CET. ExxonMobil, Chevron, AbbVie, Linde, Moderna, Cboe Global Markets and Kioxia report today, closing a heavy earnings week.

Conclusion

In our assessment the story this morning sits in where the volatility came out, rather than in the size of the rebound. The index-level reset was close to total, with VIX, VIX1D and implied correlation all sharply lower, while the Nasdaq volatility premium widened and the skew of the distribution barely moved. That mix may suggest the market has priced this week’s macro cluster as resolved without concluding that the gap between individual names is finished. Today’s data lands into a tape that has already given back most of its hedges, and options carry a high risk of rapid loss that is not suitable for every investor. Past performance is not indicative of future results.
