What this driver is
When equity futures are down meaningfully overnight, institutional investors have been net sellers during the hours when cash markets are closed. This creates a negative starting position for the session. It often reflects a response to news that broke after market close, or global market weakness that the US will open catching up to.
What activates it
The engine fetches ES (S&P 500 futures) five-day returns. When ES is down by a threshold amount, the futures risk-off driver activates.
What it connects to
Negative futures create headwinds for:
- High-beta equities — the most sensitive to broad market direction
- Momentum names — stocks that have been running tend to give back gains on risk-off days
- Opening hour selloffs — gap-down openings can trigger stop-loss selling in the first hour
Negative futures can create opportunities in:
- Defensive sectors — utilities, healthcare, and consumer staples tend to hold better when the broad market is weak
- Volatility — VIX and volatility-linked instruments rise when fear increases
The advisory nature of this driver
Like the risk-on version, this driver is advisory. The cash market may not follow futures. A negative futures setup can reverse sharply if the economic data that opens the session is positive. The engine treats this as context, not prediction.
How Decifer tracks it
ES five-day returns feed this driver. When returns fall below the negative threshold, the driver activates. Proximity warnings are generated for borderline readings.
