Three plain-English paragraphs — current state, historical base rate, and interpretation — so you walk away with context, not a dashboard.
In plain terms: 2382 is 66.6% below its highest-ever price. Dipsern checks every past time it was this far down and grades how the next 90 days usually went.
2382 (Sunny Optical Technology) is 66.6% below its historical peak. Tape reads in a historic crash, with the last trade at $81.9. Historic crashes (60%+ drawdowns) are rare events. For some assets they marked generational entries; for others they were warning signs of permanent capital loss.
History at this drawdown level is well-populated for 2382 — 194 confirmed observations in the 70%-to-65% 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 hk/china 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 2382'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.
