Saw the Kobeissi chart of S&P 500 options—August 27 and August 28 were separately labeled as NVIDIA earnings and the Jackson Hole (event) for those two days. This is the implied volatility used by exchange-traded options to price the index each day; it’s not the intraday rise/fall that already happened, and it’s not the VIX points.

In another post on Twitter, he wrote that on the 27th it was about 0.75% and on the 28th about 0.70%; those numbers were not printed on the chart. NVIDIA earnings were after the market close on August 26; the official Jackson Hole schedule is August 27 to 29—so it’s not the same statement as what he wrote on Twitter, calling the 28th the opening day.
