Daily Brief · August 21

SPY slides 0.84% overnight as PMI prints and a late Trump appearance at 19:00 keep Friday's tape cautious into the open.

Overnight Tone

SPY closed the prior session at 769.06 and is indicated at 762.60 this morning, a decline of 6.46 points or roughly 0.84%. VIX eased marginally from 16.01 to 15.7, suggesting realized fear is contained even as spot equity pressure builds. European PMI flash prints for France, Germany, and the eurozone landed ahead of the U.S. open and set a mixed cross-asset backdrop heading into domestic data.

Pre-Market Levels

SPY is trading at 762.60, down 0.84% from yesterday's close of 769.06. VIX at 15.7 remains in a subdued regime historically associated with compressed premium on near-dated options, though any upside surprise in this morning's PMI prints could shift that calculus quickly. Traders monitoring gamma exposure should note that a sub-1% overnight move on a Friday can amplify intraday swings near key strikes.

Calendar Watch

Flash Manufacturing PMI (USD, 09:45 ET, forecast 53.9, prior 53.8), Flash Services PMI (USD, 09:45 ET, forecast 54.0, prior 53.6), President Trump Speaks (USD, 19:00 ET).

Read for the Open

The 09:45 ET S&P Global flash PMI release is the primary data event to monitor in the first 30 minutes; both manufacturing and services are forecast near prior readings, so any meaningful deviation from 53.9 and 54.0 respectively could move implied volatility. With VIX at 15.7 and SPY already lower by 0.84%, the opening range may be compressed. Watch bid-ask spreads on front-week SPY options for early liquidity signals.
