Petroleo Brasileiro SA - Petrobras (PETR4) sits 21.9% off its peak and is currently in a deep drawdown, last printing at $38.54. Deep drawdowns shift the conversation from "is this a buy" to "what's broken". Sometimes it's macro. Sometimes it's the asset itself. Dipsern's data tells you which one history rewarded.

What history says at this drawdown

History at this drawdown level is well-populated for PETR4 — 349 confirmed observations in the 25%-to-20% 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.

What this means for PETR4

The Dipsern signal can tell you what historically happened next; it can't tell you whether the current setup matches the historical analog.
