In plain terms: 601857 is 63.3% below its highest-ever price. Dipsern checks every past time it was this far down and grades how the next 90 days usually went.
601857 (PetroChina Company) is 63.3% below its historical peak. Tape reads in a historic crash, with the last trade at $8.97. Historic crashes (60%+ drawdowns) are rare events. For some assets they marked generational entries; for others they were warning signs of permanent capital loss.
601857 reaches this drawdown band repeatedly in its history (237 observations), which is a large sample for the segmentation engine to compute a stable median forward return. The engine uses a rolling 90-day window and gives more weight to recent years — this lets the signal adapt to regime changes (e.g., post-COVID volatility) without losing the long-run base rate.
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 601857's own volatility history. Crash-level drawdowns are tail events with few historical analogs. The signal should be read as "here's what happened the last few times" rather than a base-rate forecast.
