History at this drawdown level is well-populated for CSAN3 — 14 confirmed observations in the 90%-to-85% band. The Dipsern engine uses these to compute a rolling median rather than a mean, because medians are robust to the kind of fat tails you find in brazilian stocks return distributions. The win rate (% of episodes that closed positive after 90 days) is shown in the segments table below.
Drawdown-based signals work across asset classes but the magnitude of meaningful moves varies. Dipsern computes the segmentation per-asset so the bands are calibrated to CSAN3's own volatility history. In crash territory, the most informative number is the worst observed forward return — not the median. The full app shows the max-loss column for the current segment.
