How to read this
The flip percentile normalizes Swiss Franc net positioning against roughly ten years of history: 39.7% means speculators are leaning short versus their own history. The 10-year z-score (-0.38) confirms how stretched that is. Readings above the 90th percentile (or below the 10th) flag a crowded trade prone to a sharp unwind.
Positioning is a risk gauge, not an entry signal. Extremes can persist and get more extreme. Pair this with the fundamentals and a confirming move before fading a crowded trade.
