The reading

How Dipsern reads COHR 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 COHR doing right now?

In plain terms: COHR is 27.5% below its highest-ever price. Dipsern checks every past time it was this far down and grades how the next 90 days usually went.

Right now COHR — Coherent Corp. — is in a deep drawdown, down 27.5% from its record high. Last price: $309.55. 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 COHR specifically.

Historical base rate

What history says at this drawdown

History at this drawdown level is well-populated for COHR — 698 confirmed observations in the 30%-to-25% 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 us 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 COHR

For US large-caps, drawdowns of 20-30% are typically driven by macro repricing (rates, earnings, sector rotation). Single-name 50%+ drawdowns are usually structural — the signal alone won't tell you which, but the segments table will show whether prior episodes recovered. 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.
