Equal notional from each holding’s inception mark, re-marked at the two-sided mid. Percentages only, size-blind — never a cash figure and never a performance claim.
Cost to cross is the weighted half-spread at the touch on the newest mark tape: what entering at the quote rather than the midpoint would have cost. It is the price of the FIRST unit and says nothing about the tenth — the resting size beside each holding is published so a reader can judge whether their own size fits. It is not deducted from any return above.
A published measurement of what these markets did together. Not an account, not directly investable; W.E.T. never handles orders.

Daily close
34d published · interactive34 published close(s) — 0–100 (Benign → Extreme). Drag to pan, scroll to zoom. One slot per published close, not one per day: dates on the axis are real, the spacing between them is not. 11 day(s) inside this window published no close and are not drawn at all. For the calendar-true spacing, read the chart below. Drawn as a line, not candles: a daily close carries no open, high or low, and a candle would assert an intraday range nobody observed.
History & 14-day projection
solid = 34d published · dashed = projected · shaded = 80% bandModel extrapolation of the published series (robust trend, 34 readings, slope +0.04/day, projection σ 7.1 pts/d widened for a 34-reading sample) — a benchmark projection, not a W.E.T. forecast.

- High vs low
- Higher = more record-heat / major-storm / disaster risk priced. Lower = benign.
- Who cares
- Weather desks, insurers, and anyone tracking whether the market sees a dangerous season ahead.
