Three plain-English paragraphs — current state, historical base rate, and interpretation — so you walk away with context, not a dashboard.
In plain terms: RAIL3 is 48.6% below its highest-ever price. Dipsern checks every past time it was this far down and grades how the next 90 days usually went.
Rumo SA (RAIL3) sits 48.6% off its peak and is currently in a severe drawdown, last printing at $13.03. A 35-60% drawdown is the territory where most retail investors capitulate. It's also where the highest-probability historical entries have clustered for resilient assets.
History at this drawdown level is well-populated for RAIL3 — 60 confirmed observations in the 50%-to-45% 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 RAIL3's own volatility history. Severe drawdowns are where Dipsern's segmentation provides the most edge: ordinary base rates don't apply, but the asset's own history at this exact depth does. The forward-return distribution here is bimodal — either rapid recovery or continued decline.
