How Dipsern reads CMIN3 right now.

Three plain-English paragraphs — current state, historical base rate, and interpretation — so you walk away with context, not a dashboard.

Snapshot

How is CMIN3 doing right now?

In plain terms: CMIN3 is 31% below its highest-ever price. Dipsern checks every past time it was this far down and grades how the next 90 days usually went.

As of the latest market close, CSN Mineracao SA (CMIN3) is trading in a deep drawdown, 31.0% below its all-time high at $4.35. Asset price action of this severity has historically marked attractive entry zones — but only when fundamentals weren't permanently impaired. The historical median return below quantifies that pattern for CMIN3 specifically.

Historical base rate

What history says at this drawdown

History at this drawdown level is well-populated for CMIN3 — 105 confirmed observations in the 35%-to-30% 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.

Interpretation

What this means for CMIN3

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 CMIN3's own volatility history. Below 20% drawdowns the historical median forward return often becomes attractive — but with rising variance. The win-rate column in the segments table is more useful than the median at this depth.
