Summary

Signal Trend (Last 7 Days)

How to read this: look at the trend column. A string of worsening arrows means risk is building, even if the signal level hasn't changed yet.

Decision Thresholds

The bottom line: find the row marked "YOU ARE HERE" and follow its suggested action. Each level maps to a specific crash probability and a concrete step to take.

Signal Level

Historical Outcome

What This Means For You

LOW (37% of days)

Normal positioning

5.5% chance of 3% crash in 7d

Market conditions are typical. Stay invested as planned.

MEDIUM (35% of days)

Moderate risk signal

15.3% chance of 3% crash in 7d

Risk is above normal. Historically, tighter stop-losses have helped at this level.

HIGH (21% of days)

Elevated risk signal

29.2% chance of 3% crash in 7d

Nearly 1-in-3 chance of a significant drop. Historically, reducing exposure has been beneficial at this level.

SEVERE (8% of days)

Maximum defense

41.1% chance of 3% crash in 7d

Historically rare and dangerous. In past episodes, defensive positioning has preserved capital.

How Much Could the Market Drop?

Estimated worst-case S&P 500 loss over different time periods. "Likely Worst" means 95% of outcomes are better than this number.

90-Day Signal History

What's the point? Seeing three months of signal changes alongside SPY price helps spot whether risk spikes predicted actual drops — or resolved harmlessly.
